How to check the engine on the vacuum cleaner video review

Electric engines are present in most devices of household appliances. It is electricity that continues to be the most universal source of energy. There is nothing surprising in the fact that electrical equipment (including household) is so popular. However, perhaps everyone faced the failure of electrical engineering. At the same time, the causes of the breakdown can be different. In order not to waste time to take, for example, a vacuum cleaner in repairs and find out that the restoration will cost the price of the actually a new vacuum cleaner, it is useful to be able to diagnose a breakdown on its own.

The engine for the vacuum cleaner can be purchased separately. But do not rush to buy spare parts, first diagnose. Of course, the user initially does not (in most cases) of the necessary knowledge for a diagnostic study of household appliances. In fact, everything is not so complicated! All that is required is the multimeter.

Various types of electric engines

Technique uses various electric motors. And the choice of diagnostic method depends on the type of engine. As an example, the following electric motors can be cited:

In the first case, the diagnosis is quite simple. As a rule, the indicated engines have only two windings. Therefore, in order to verify the correctness of the functioning of the engine, it will have to disassemble it.

We test the coils using an ohmmeter (switch the multimeter to the required mode). The resistance of the working winding should be 50% less than that of the starting. Be sure to test the coils on a breakdown on the case. This resistance should be very large.

If the indicator is small, you have to rewind the stator.

How to call: conditions

Before checking the electric motor for a malfunction, you must make sure that the cord and plug of the device are absolutely good. Typically, the absence of a violation of the supply of electric current to the device can be judged by a luminous control lamp.

Having made sure that the electric current enters the electric motor, it is necessary to dismantle it from the device case, while the device itself must be completely de.energized, during this operation.

Checking the anchor and stator of the electric motor is made by a multimeter. The sequence of measurements depends on the model of the electrical unit, while before the electric motor is called, you should make sure that the measuring device is about the serviceability.

The most frequent “breakdown” of multimeters is a decrease in the battery charge, in this case you can get distorted results of resistance measurements.

Another important condition for calling the electric unit correctly is the complete suspension of any other cases and devote the time to the performance of diagnostic work, otherwise you can easily skip any section of the electric motor winding, which may be the reason for the malfunctions.

Asynchronous engine

This type of electric motor is often used in household devices operating from the 220 V network. After dismantling the unit from the device and a visual inspection, at which a short circuit will not be found, diagnostics are carried out in the following sequence:

  • Make measurements of resistance between engine conclusions. This operation can be carried out by a multimeter, which should be converted into a resistance measurement mode up to 100 Ohms. A working asynchronous engine should have a resistance of about 30. 50 Ohms between one extreme and average output of the connected winding, and between another extreme and medium contact. 15. 20 Ohms. The measurement data indicate the full serviceability of the starting and main winding of the unit.
  • Diagnose current leakage to “mass”. In order to call the unit to leaks of electric current, it is necessary to transfer the mode of operation of the multimeter to the resistance measurement position up to 2,000 kOhm and alternate connection of each terminal with the electric motor body determine the presence or absence of insulation damage. In all cases, any indications should not be displayed on the multimeter display. If an analog device is used to measure the leak, then the arrow should not deviate in the process of diagnostic manipulations.

If deviations from the norm were identified during the measurement process, then the unit must be disassembled for more detailed studies. The most common breakdown of asynchronous electric motors is an interval circuit.

With such a malfunction, the device overheats and does not develop full power, and if the operation of the device is not stopped, then an electric unit can be completely out of order.

To call the Interpretation circuits, the multimeter is converted to a resistance measurement mode up to 100 Ohms. It is necessary to call each stator contour, and compare the results obtained. If the resistance in one of them will differ significantly, then this way can be confidently diagnosed with an interval closing of the asynchronous electric motor winding.

Checking the anchor for an interval circuit

Electric machines consist of a rotor and stator. The stator is fixed windings laid in the case. An anchor is a mobile part, therefore, as a rule, particles of dirt and lubrication fall on it and an oxidized plaque forms under the influence of temperature. It can cause faulty operation or failure of the Rotor of an electric machine. It is found by a visual inspection. Narar can cause an interval circuit in anchor. As such, the rotor of the electric motor under normal operating conditions does not wear out. Over time, only the current.cooping brushes are subject to replacement if their length does not correspond to the permissible size. However, long loads cause the heating of the stator windings, which as a result contributes to the formation of soot. Interpretation of the anchor can happen with mechanical damage. The presence of chips, dents, scratches and cracks is unacceptable on the rubbing surfaces. The closure between the turns of the anchor windings occurs in the case of leaving the bearing nodes. Then the anchor is overwhelmed, which leads to damage to the lamellas. Another reason for the closure is the effect of moisture. When water drops hits on metal surfaces, the corrosion process begins. The rust makes it difficult to rotate the anchor, the current loads are growing, the percentage can be excluded as a result, which in turn can lead to interval circuit during prolonged operation.

It is possible to diagnose this malfunction at home. Carry out this procedure using an inductance coil called a throttle.

Using this device, you will be able to find out the direction of reset, as well as the order in which the coils of the winding are connected to the collector lamellas.

Thus, the anchor is checked for the interval circuit.

It is not at all difficult to make such a device with your own hands, it’s enough to get acquainted with our instructions.

For assembly of the device. It will require P. figurative transformer iron. It can be removed from a vibrational pump like baby.

We disassemble the structure and remove P. figurative transformer iron.For this, the lower is the lower part of the pump. so that the polymer, which floods the coil, melted.

Next, using the improvised tool, cut the edges on the transformer gland, as shown in the photo. When processing, remember that the iron is puff, so all operations must be carried out carefully so that the bully does not form. After on the sandpaper, we remove all the sharp edges on the product. This is necessary to maintain the integrity of the enamel supply.

It is not necessary to observe the strict size of the angles, the main thing is that the anchors of different sizes are easily located in the prepared place.

The next action will be the manufacture of coils. To win the size of the device and the throttle did not turn out to be too bulky, we will make not one, but two coils that will be placed on both sides of the P-shaped iron. For this you will need:

We measure all sizes of the P-shaped transformer iron in their maximum values. Next, we transfer them to cardboard and draw a scan of the body of the future coil. In this case, it is necessary to take into account the size of the groove of the core. Next, the stupid end of the scissors is drawn along all lines of excess. This will help to bend cardboard without problems. Cut the scan. In the same way we make a pattern to the other side. Now we need to prepare lids for coils. There are 8 of them. We mark the blanks for the covers on the cardboard. We cut out the outer circuit with scissors, inner with a sharp knife.

Next, glue the covers with prepared scanes and get two skeletons of future coils.

Now you need to wind the wire to the coils. To do this, we will use the calculation of the transformer. First, we determine the area of ​​the cross.section of the core by changing its length and width. In our case, the area was 3.7 cm x 2.2 cm = 8.14 cm 2. Next, divide 13200/8.14 = 1621 round. We round this amount to 1700 turns and equally distribute between the two coils, it turns out 850 turns. This amount can be wound without problems manually. At the same time, an error of 20-40 turns will not affect the result. But it’s still better to make a mistake towards the increase. Before winding, it is necessary to make holes into which the ends of the wire will exit. A heat.assembly cambric is put on the free end of the wire. The end of the wire is inserted into the hole and then the winding process is ongoing. At its end, we solder the wiring with Cambrick to the other end and insert it into another hole. Just so wound the second coil.

After. How both coils are ready. We put them on P. a figurative core. In this case, the outputs of the wires should be located below on one side. Important. so that the coils are wound identical. The turns are directed the same. and their endings are bred in one direction. This is followed by the connection of induction coils and the supply of network voltage (220V) to their ends.

To test a homemade throttle, we will use the factory manufacturing device. First, check the anchor for the interval circuit with an industrial device and the place of sticking the plate we mark with chalk. When checking the rotor by our throttle, the plate will be primagnetized in the same places. We will summarize, the device is made correctly, the results are identical.

How to check and disassemble the vacuum cleaner engine

Before you start checking and disassembling a vacuum cleaner to replace a motor or electric motor, you need to figure out which types of motors exist, how to determine the malfunction in the motor and of course how to choose a new motor for a vacuum cleaner. The first reason why the engines are changed can serve as heating, t.e. When working, the vacuum cleaner engine is heated, while it can heat up to a temperature of more than 60 degrees (the hand cannot tolerate direct contact), which indicates a clear malfunction or filter system (filters are clogged and they need to be replaced) or about the inter.flip circuit of the stator of the motor

The main malfunctions of vacuum cleaners

call, samsung, vacuum, cleaner, multimeter

Let’s analyze each of these malfunctions individually and briefly list the possible causes of this behavior, but it is worth noting that for the repair of any household appliances, the wizards for the repair of vacuum cleaners should be called, since only he can 100% establish the true cause and eliminate it competently And quickly, but we should pay for this service, and we always strive to save at least a little and buy something cheaper.

Does not turn on and does not respond to inclusion. this malfunction implies the presence of a good outlet and lack of damage to the wire, the latter by the way is very often found and to check this malfunction you will need to disassemble the case (see. Dismantling point) and check the entire wire with a multimeter “on the call”. If the vacuum cleaner has a speed adjustment, then most likely the module of this very adjustment is faulty, of course with a good motor (see. Section Verification of the motor)

It is heated when working-here it is immediately worth noting that any EL engine is warming during operation and this is considered standard to the level of 40-50 degrees, this is due to the fact that not all electricity consumption goes into the energy of the impeller rotation and part of it is dissipated as heat. plus during rotation one way or another, friction/sliding and brushes and brushes and bearings occur, and as we know, heat is also released at the same time.

Heating problems should be divided into two groups. This is the first to score a filter, while vacuum cleaners have a filter as a suction that delays all dust and collected dirt, as well as “highs” (not entirely correct word, but understandable). Also, the problem can be in the brush or in the hose of the vacuum cleaner and here the simplest thing is to disconnect the hose and try to turn on without it if the sound changes, as it were, “easier”, then the problem is there.

The second type of cause of overheating during operation is a large current consumption of coils caused by an interwoven closure, as a rule, such a closure causes the first overheating or getting water, which is why a part of the turn is raised and inductance (resistance to alternating current) drops, due to which the consumption of current increases, After all, it became easier for him to pass, and the design of the motor is not designed to disperse so many heat.

The noise when working indicates a malfunction of the filter system, and when they are reflected, it indicates the production of bearings, which, when moisture hit, can begin to corrode, and an increase in the roughness of the plane sliding balls leads to a noise, like driving a car on a spells on asphalt in the summer. Over time, this noise increases and most likely leads to a complete breakdown of the motor, but unlike the inter.flip circuit (heating during operation), you can replace the bearings without changing the motor itself.

Sparking. any collector vacuum cleaner has a brush node, the engine brushes are made of graphite and transmit current without losing contact when rotating. Often the brushes wear out themselves and wear out the collector to such an extent that during rotation, contact is lost and sparking, which is considered to be regular in moderate limits, increases to very visual, becoming ring (the spark passes the full circle of the collector)

Dismantling of the vacuum cleaner case

Before checking the vacuum cleaner, it is necessary to disassemble its body, and sometimes this procedure is very complex and tiring, moreover, vacuum cleaners that cannot be disassembled, without obvious damage to the case, since the entire assembly occurs on the latches in such a way that it is impossible to disassemble A vacuum cleaner for repair or simply such a technology reduces the reduced process of production.

In this case, when disassembling the case, it was necessary to unscrew 8 self.tapping screws of the same size, the housing itself was “halved” quite easily and did not take much time

Checking the motor condition

To check the vacuum cleaner engine and electrical wiring, you do not need any super device and accurate multimeters, the call mode is enough, of course it is better to have professional equipment capable of measuring inter-flip circuit, but often such devices are very expensive and their use is not justified in the repair of fine equipment, moreover if you can also buy an engine for a vacuum cleaner for reasonable money and at a price they are suitable for replacement, then the motor is said to be bought for a hoodie, meshrubes or coffee grinders, since the cost of this technique is very low.

Dismantling the electric motor of the vacuum cleaner

It is cost.effective to disassemble the vacuum cleaner engine in two cases, the first is to replace the bearings that we wrote about in the noise section, and in the second case, for the restraint of the impeller, which I really do not like and consider this repair a temporary measure and wasted by time. Any vacuum cleaner motor rotates with frantic turns and with the slightest dysbalance or deformation of the impeller, vibration and noise increase, this leads to an increase in loads on the bearings and they will soon also refuse.

Everything has a limit of profitability, of course, if you are a pensioner and think what to do on a well.deserved rest, you can thus pass a couple of evening, but as practice shows, this does not lead to really useful

How to check the anchor of an electric motor

Different types of electric motors are installed in household appliances and equipment. These differences depend on the operating conditions, purpose and the functions they perform. For example, in electric drifts, mixers, kitchen combines, vacuum cleaners, washing machines and other devices with a frequent change in the speed of rotation of the shaft, collector engines are used. If it is required to provide long.term stable mode of operation, then in such equipment, asynchronous electric motors are already used, most suitable for small homemade machines. However, in all cases, you often have to check the anchor of the electric motor at home.

Collector electric motors are designed to work from household networks, a voltage of 220V. Almost all of them are synchronous units. Unlike asynchronous electric motors, collector devices consist of a fixed stator and a rotating winding on the shaft. anchor. The voltage is supplied to them using a brush-graphite device, which is the collector. The main reason requiring the testing of the anchor and other details is the appearance of sparks. Active sparking indicates the wear of the brushes and the collector unit or violation of contacts. In addition, sparks may appear as a result of an interval circuit, that is, the closure of windings in the collector. The appearance of such violations requires high.quality diagnostics, starting with a visual inspection and ending with a multimeter check.

The initial inspection allows you to identify broken or burnt windings, as well as burnout at the points of their connection. Therefore, first of all, attention should be paid to the condition of the windings and integrity of the turns. If the windings are blackened completely or partially, this already indicates certain problems with the anchor. Sometimes the insulation is just sniff enough to determine the characteristic smell of Gary.

accurate information can be obtained by checking the anchor by a multimeter. The call is performed in stages, capturing all engine elements:

  • Initially, pairing conclusions of the stator windings to the lamellas are nicknamed. Resistance on each of them should have the same value.
  • Next, the resistance between the lamellas and the anchor body is checked. Normally it should be endless.
  • The integrity of the winding is checked by calling the conclusions.
  • After that, the condition of the chain between the stator body and the terminals of the anchor winding is checked. If there is a breakdown on the case, the household device is strictly prohibited to connect to the voltage. In this case, mandatory repair or complete replacement of faulty parts is required.

After repairing the collector electric motor, you need to connect all the elements to each other and connect the device to the 220V power supply. If the unit works normally, then the repair is carried out correctly.

Checking an asynchronous electric motor

In addition to collector, in everyday life you can also find asynchronous engines installed in some models of washing machines or in compressors of refrigerators. often they are used in compressors, pumps, various machines and other equipment. Despite the high reliability, these electric motors are also subject to breakdowns and malfunctions. In these constructions, the role of the stator is played by the role of the anchor, so the visual inspection should be started with them.

Often, windings stop working when they damp or, there was a break in the turns. Therefore, if the engine has not been operated for a very long time, it is necessary to check the insulation resistance using a megammeter. In the absence of a mgammeter, the unit for prevention is recommended to disassemble and dry the stator windings for several days.

It is possible that the cause of the malfunction lies not in the electric motor itself, but is associated with any other factors. Therefore, before starting to repair the unit itself, you should make sure that there is a voltage, check magnetic starters, connection cables, armal relay. If the circuit has a capacitor, it also needs to be checked. If all of the listed elements are serviceable, you can proceed to disassembling the engine for the initial inspection. The check should be carried out in the complete absence of power supply. It is necessary to prevent spontaneous or erroneous inclusion of the unit.

During the inspection, in addition to other parts, the stator windings are especially carefully checked. They should be whole, without protruding or torn wiring. Particular attention should be paid to black spots indicating the possible burning of wires. In good condition, the conductors have a dark red color. Blackening occurs when the electrical insulating varnish applied to their surface. During the examination, complete or partial burnout of the winding and an interval circuit can be revealed. With partial burnout, the engine will work and heat up quickly. Therefore, the winding in any case is rewinded completely.

If an external inspection has not given results, further diagnostics should be carried out using measuring devices. Most often, a multimeter is used for these purposes to determine the integrity of the winding, the presence or absence of breakdown on the body.

In the engines on 220v, launch and working windings are nicknamed. The trigger resistance should be 1.5 higher than that of the working. In 380V electric motors connected by a star or triangle, the circuit is disassembled, after which each winding is alternately nicknamed. The resistance on each of them should be the same, with a deviation of no more than 5%. Also, all windings are necessarily nicknamed among themselves and on the case. If the resistance value is not infinite, this indicates the presence of a breakdown of windings on the body or among themselves. In this case, their complete rewind is required.


Separately checked the insulation resistance of engine windings. In this case, the multimeter will not help, you need a 1000V megammeter, connected to a separate power source. When performing measurements, one wire of the device touches the engine housing in an unpainted place, and the other wire is alternately connected with each winding output output. If the insulation resistance is less than 0.5 MOM, then the engine requires drying. When performing measurements, you must be careful and not touch the measuring wires. The measured equipment should be de-energized, the duration of the measurement is at least 2-3 minutes.

The largest difficulty is the search for interevter circuit. It cannot be identified during visual inspection. For three.phase engines, special inductance meters are used, which normally show the same value on all windings. If there is damage, the inductance of such a winding will be the lowest.

How to check the electric motor with a multimeter: checking the rotor and stator for an interval circuit, calling the asynchronous and three.phase engine

Standard diagnostics

While taking the diagnostic device, inspect the anchor. There are usually damage here. If the wiring is melted, the burnt insulation varnish will leave black traces as it is also called a specific smell. We meet bent non.crumpled turns or conductive particles, nettles, soldiers of solder. These particles are the cause of a short circuit between turns. Lamels have bent edges called cocks to connect with the winding.

Due to the violation of these contacts, the lamella is burned out.

SAMSUNG vacuum cleaner restoration part 01

Other damage to the collector: raised, worn out as well called burnt plates. Graphite from brushes can accumulate between the lamels, which also indicates a short circuit

Dismantling of corner grinders

How to check the stator angular grinding machine (corner grinder)? You need to start with disassembling the device. You will need a screwdriver to do the work.

  • Remove from the surface on which the corner grinding of the corner grinding will be carried out, all unnecessary details.
  • Remove the working disk.
  • Unscrew the screw.
  • Unscrew the screws.
  • Paste the casing towards the cord.

The stator is located on the outer side of the engine, on top of the rotor. To get the stator first you have to remove the brushes, then remove the gearbox and then pull the anchor from the corner of the corner of the corner. The rotor from the stator before checking you need to remove. Inspection is recommended to be carried out in bright light. First of all, you need to carefully examine the winding and make sure that there are no visible breaks on it. If the inspection has not revealed the cause of the stator malfunction, then you will need a special device for verification.

Testing collector engines

The situation is somewhat different here. It is necessary to start with pair testing of the collector lamellas. over, the resulting indicators should be almost equal to each other.

We also test on a breakdown on the case. we put one probe on the anchor, the other on the case. Resistance indicators in such measurements should strive for infinity (very high resistance).

Pay attention to the integrity of the stator winding. Attach one probe to the surface of the stator, the other to the output of the winding. High resistance indicators are also predominant here.

Almost any malfunctions in the operation of the vacuum cleaner can be caused by engine malfunction. Does the vacuum cleaner want to turn on, in general, or just weakly draws the garbage, demonstrating the power below the nominal. the engine can be to blame for everything. Not to mention extraneous sounds, roar and howling: only the engine is capable of such sounds in the vacuum cleaner. How to check the engine of the vacuum cleaner and see if it is working?

First, the vacuum cleaner should disassemble and dismantle the engine. The instruction for the vacuum cleaner may well serve as an instructions for disassembly, since there is nothing beyond the complicated in this procedure. Most importantly, be sure to photograph the wire connection scheme so that after the reverse assembly you do not cause a short circuit. It may happen that you will need a new engine for the Samsung vacuum cleaner. On a specialized site, it is easy to choose a motor using the possibilities of online selection of mechanisms or assistance to a consultant (for example, here-http: // alm-zapchasti.COM/CAT/PYLESOSY/MOTORY). But first try to check the motor. maybe repair is possible! And the masters of the Alm-Zapchasti service will help you with this.

Samsung vacuum cleaner motor

If the motor does not show any signs of life, then you need to look for a breakthrough place. Try to start examining the motor visually. Very often the cliff occurs at the place of fastening, and you will see it. And if you are even more lucky, you can even clean and solder the torn wire without disassemble the engine for the Samsung vacuum cleaner. In any other case, a complete disassembly of the vacuum cleaner engine will require and the anchor check of the Interpreter close. How to disassemble the vacuum cleaner engine? The main thing is to carefully unscrew the central nut, and then you just need to remove all the details strung on it from the shaft. Next, you can start checking the anchor.

In general, given the troublesome of checking the vacuum cleaner engine and the availability of spare parts, many immediately make a choice in favor of a complete replacement of the engine in the assembly without trying to make out the motor and see what is the matter what is the matter. This is how it is recommended to do all home masters who do not have the experience of repairing electric motors, but can do the simplest mechanical assembly work. It is better for everyone else to immediately contact a specialized repair service. Let’s hope that these tips will help you, and your vacuum cleaner will work again like a newcomer!

Good day to everyone! Help others! Yesterday covered the Vitek 1600W vacuum cleaner, t.e. Just refused to turn on. I dismantled the case, checked the power from the cord to the contacts of the reeling coil, from the contacts to the button, the working button, the power supply comes to the engine, but it does not twist. Brushes are visually normal. I think the engine burned out (the question is how best to check it with a multimeter and finally calm down. Thanks to everyone in advance.

How to repair the engine of the vacuum cleaner at home: instructions video

The vacuum cleaner can serve as a certain time, but it happens that during the next cleaning it begins to make a lot of noise, crack, sparkle, bask, smell, work with jerks, or completely stops working with a nasty rattle. We will figure out what to do. carry the device for repairs to the service or try to repair the vacuum cleaner engine yourself.

If you decide to make out your “assistant” with your own hands, this article is for you. Immediately warn. you can not repair everything, even if the technique does not show signs of life.

IMPORTANT! In this article we will consider the most common, “universal” type of vacuum cleaner engine. collector (with brushes) on sliding bearings. There are electric motors of other types (walking, linear, synchronous, asynchronous, blessed, inactive), but much less often. consult with the masters about them.

Despite the restriction, the article is relevant for most vacuum cleaners models, such as: Ametek H / Ametek, Bosch / Bosch, Bork / Bork, Cleanfix / Clinfix, Centec / Century, Daewoo / Daewoo, Doffler VCC / Doffler, Dyson / Dyson, Eio TAGA Duo / EO Targa Duo, Electrolux Ergorapido, Twin Clean / Electrolux Ergorapido, Twin Klin; Elenberg / Elenaberg, Harley Davidson / Harley-Davidson, Hoover / Huver, Kirby / Kirby, Karcher / Kerher, LG / LV, LG or, as is customary, El Ji; Makita / Makita, Miele / Mile, Moulinex / Mulinex, Philips / Philips, Rainbow / Rainbow, REDMOND / REMOD, ROOMBA / RUMBA, ROWENTA / ROVENT, SAMSUNG SC, VC / Samsung; Sanyo / Sanyo, Siemens / Siemens, Scarlett / Scarlett, Thomas Twin Aquafilter / Thomas Twin, VAX / Vax, Vitek / Vitek, Zanussi / Zanussi, Zelmer Aquawelt / Zelmer Aquavelt, Vityaz, Vityaz, Vityaz, Viegs Orion, Rocket, Tikhon, Typhoon, Urals,Seagull, bumblebee, stihl and others, including auto.peppers, detergents, industrial and building models.

The device of the vacuum cleaner engine

Before starting the repair, we will figure out the basics and study the “materiel” a little so as not to shift and not spoil everything completely.

On the vacuum cleaner there is an ordinary alternating current electric motor operating from 220 volts. Consists of a stator attached rigidly to the body, and the rotor, which rotates relative to it and converts electrical energy (current from the outlet) into a mechanical. This energy rotates the engine shaft and forces the connected mechanism to work, absorbing air.

The rotor rotates thanks to electromagnetic induction, which occurs under the action of alternating current in the windings. The working mechanism consists of a impeller, which, when rotating, creates an air flow directed into the filtering system of the unit.

With an ordinary bag

An ordinary bag passes the air, but delays and accumulates the accumulated dust and dirt. that is, it is both a vacuum cleaner and a filter (possibly even the only one in the model). This is the most common air purification technology. it can be found in cheap models and in instruments for professional cleaners. It was devices with a bag that one of the first began to produce for domestic use.

Advantages: Simple, reliable, inexpensive. Disadvantages: When filling the bag, the absorption power decreases, it is inconvenient to extract dust.

With an aquafilter

Such a vacuum cleaner initially sucks air with dust and dirt, then passes it through an aquafilter. a tank with water. In this tank, particles of dirt and dust are binded to the liquid and settled in a container, and clean air is thrown out. the vacuumber must be filled with water to a certain level, and then rinse after each cleaning. Unlike detergents, it does not have a special spray pump and more acceptable at the price.

Advantages: high.quality air purification of dust, humidification of air during cleaning, allows you to collect water from surfaces (conveniently with wet cleaning). Disadvantages: too large, heavy and clumsy; need a lot of space for storage. weight can reach about 10 kg. require a lot of care and maintenance.

Cyclone system

Vacuum cleaners of such a system are called “cyclone”, because when absorbing air creates a slight swirling “cyclone”. The air flow casts particles of dust and garbage on the walls of a cylindrical vacuumber, and clean air exits through the central hole. Then the air passes the additional cleaning through a regular paper filter or a special shifter Hepa filter installed on the rear in the form of a cassette. Dust and dirt accumulate in the most cyclone chamber. When it is filled and ceases to perform its functions, it is easy to pull it out and empty into the garbage bucket.

Advantages: inexpensive, functional, best in parameters price-quality. Disadvantages: light garbage is poorly removed. hair and fluff of animals, hair, threads. “Beat” with small charges of static electricity, which is formed during rotation. The work depends on the stability of the air flow: when cleaning the sofa or curtains, its intake decreases sharply, the garbage flies out onto the filter and pollutes the cassette. Compact models are not suitable for thorough cleaning, and full.fledged consumes a lot of electricity. no more noise than other models.

A sequence of disassembly

Here we will tell you how to get to the vacuum cleaner engine, and consider the disassembly process in more detail.

Disconnect the hose and disassemble the case

As a rule, it is necessary to unscrew the four bolts with a long cross with a long cross, fastening the two halves of the case. Sometimes you have to remove some overhead elements, for example, a turbine. The main thing is not to damage anything and unscrew all the bolts before separating parts of the case.

Remove the motor

Before extracting the engine, turn off the power terminals and other electronics.

Remove the engine cover

The cover is covered with a seam around the entire perimeter. To remove it, carefully squeeze the seam with pliers. Under the influence of light blows, the cover should separate from the main body.

We pull out the brushes, unscrewing the pressing screws

As a rule, the brushes are pressed to the rotor with small springs. if you unscrew the clamps, the springs can fly out in an unknown direction.

Elimination of Samsung vacuum cleaners

The electric motor is the main component of any modern household electrical engineering, whether it be a refrigerator, a vacuum cleaner or another unit used in the household. In the case of any device failure, it is first necessary to establish the cause of the breakdown. To find out if the engine is in good condition, it must be checked.

It is not necessary to carry the device to the workshop for this, it is enough to have a conventional tester. After reading this article, you will learn how to check the electric motor with a multimeter, and you can cope with this task yourself. There are different modifications of electric engines, and the list of their possible malfunctions is quite large.

Most problems can be diagnosed using the usual multimeter, even if you are not a specialist in this area.

The first stage of any diagnosis is visual inspection. If even the burned windings or the broken parts of the motor are visible with the naked eye, it is clear that the further check is meaningless, and the unit should be taken to the workshop. But often the inspection is not enough to identify problems, and then a more thorough check is needed. Asynchronous power units for two and three phases are most common. The order of their diagnosis is not exactly the same, so you should dwell on this in more detail.

There are two types of malfunctions of electrical units, and regardless of their complexity: the presence of contact in the wrong place or its absence. The composition of a three.phase motor operating from alternating current includes three coils that can be connected in the form of a triangle or star.

There are three factors that determine the performance of this power plant:. The closure on the case is usually checked using a megammeter, but if it is not, you can do with an ordinary tester, putting on it the maximum value of the resistances. megaoma.

There is no need to talk about high accuracy of measurements in this case, but approximate data is possible. Before you measure the resistance, make sure that the engine is not connected to the mains, otherwise the multimeter will become unusable.

Then you need to calibrate, putting the arrow on zero probes, while must be closed. Check the serviceability of the tester and the correctness of the settings, briefly touching one probe of another, it is necessary every time before measuring the size resistance. Attach one probe to the electric motor body and make sure that there is a contact. After that, remove the device’s readings, touching the engine with the second probe.

If data is within the normal range, connect the second probe with the withdrawal of each phase alternately. High resistance and more MOM indicates good isolation. Then you need to make sure that all three windings are intact.

You can check this by calling the ends that go into the box of the electric motor conclusions. If a cliff of any winding is detected, the diagnosis should be stopped until the malfunction is eliminated. The next checkpoint is the definition of short.closed turns. Quite often, this can be seen during a visual examination, but if outwardly the windings look normal, then the fact of a short circuit can be established by unequal consumption of electric current.

Diagnosis of power units of this type is slightly different from the above procedure. When checking a motor equipped with two coils and sales from a conventional power grid, its winding must be raised using an ohmmeter. The resistance to the case must be measured. normally it should be very large, as in the previous case.

The low resistance indicator indicates the need to rewind stator. Of course, to obtain accurate data, such measurements are best carried out using a meter, but such an opportunity at home is rare. Having dealt with the diagnosis of asynchronous engines, we proceed to the question of how to call the electric motor by a multimeter if the power unit belongs to the collector type, and what are the features of such checks.

To correctly check the performance of these engines using a multimeter, you need to act in the following order:. Check the electric motor using a multimeter for an interwovery closing. For this, a special apparatus is used, with which the anchor is checked. Often, electric power plants are equipped with additional components designed to protect the equipment or optimize its operation. The most common elements built into the motor are:.

An ordinary multimeter, as a rule, is enough to diagnose most of the problems that can occur in electric motors. If you establish the cause of the malfunction with this device, it is not possible, the check is carried out using high.precision and expensive devices, which are available only to specialists.

This material contains all the necessary information on how to correctly check the electric motor with a multimeter in domestic conditions. When the failure of any electrical engineering is the most important thing. to call the motor winding in order to exclude its malfunction, since the power plant has the highest cost compared to other elements.

How to call the electric motor multimeter

In the household, almost all collector electric motors are synchronous devices. How they are arranged and work read in our previous article. Collector electric motors are in washing machines but not in all models. vacuum cleaners, power tools, children’s toys, etc.

Dry and wet cleaning of “insides” from dust

Often the cause of a suspicious rumble of a vacuum cleaner and an unpleasant odor is a closing of dust inside him. It is better to remove the dust in “dry” methods so as not to damage the fragile electronic filling and do not disrupt the functions of conductive paths on the board. A small soft brush is suitable for cleaning. You can also use a room fan. If dust and dirt cannot be removed “dry”, after moisture hit all the parts, you need to dry out as soon as possible. Plastic elements are pretended to be washed under running water. They should be assembled back only after they are completely dry.

The drum and cable are well lend itself to dry cleaning, like the plastic casing of the engine. If the casing does not work without using water, make sure that it does not hurt the electric circuit. As a tool for dry cleaning, you can use another vacuum cleaner with a suitable nozzle. This is how the dusty plates of the engine and windings are cleaned from the dust of the dust. Strong pressure of the air perfectly cleanses the board and its small details. even with strong contaminants.

Testing a two.phase model

Stator and many other structural elements of a two.phase electric engine have their own distinctive features, which determine the features of the test. We include the following points to the features of checking a two.phase electric engine:

  • In this case, the resistance on the case is necessarily checked. Too low indicator indicates that the stator rewind is necessary.
  • To obtain more accurate indicators, it is recommended to use a megammeter, however, a similar measuring tool is extremely rare at home.

Before testing the electric engine, a visual inspection should be carried out. Mechanical damage can lead to serious problems with work.
