What types of engine are in washing machines?

Machine machines equipped with inverter engines began to be released relatively recently, but it was already firmly settled in the household appliance market. In comparison with its “collector” brothers, such a type of engine is characterized by a higher cost and largely surpasses standard motors, namely, in terms of reliability of operation and greater wear resistance.

Today, the competitive struggle between these types of engines reaches its peak, and the consumer should deal with the benefits and disadvantages of each of them to determine the inverter or standard engine to choose.

Varieties and features of engines

In washing machines, 3 main types of engines are used: collector, inverter, asynchronous. They differ technically and functionally different, have their advantages, minuses. Consider each type in detail.

View # 1. small and budget collector

The collector engine is equipped with most styrals on the market. Its design is an aluminum case, inside the rotor, stator, tachometer and two brushes.

The latter are placed in the device in order to ensure contact between the motor and rotor. Through them are fed by an anchor, a magnetic field is formed, which starts the rotation. The voltage in the network significantly affects the speed of this rotation.

The collector engine is located at the bottom of the machine design, with the pulley of the drum it is connected by a belt. Brushes and belt refer to disadvantages. Brushes are abrase over time, the belt needs to be replaced, because with time it wear out and stretched.

The presence of electrical brushes is distinguished by this type of engine from the rest: they are peculiar to rustle or rustle during the work of the washing

  • It works from direct and alternating current;
  • small in size;
  • simple repair if the breakdown happened;
  • Non-flat control electrical system.

To overcome the power of the belt friction, the whole mechanism spends more energy. This leads to a low efficiency due to increased electricity consumption.

But the statement is rather controversial, because the main consumption falls on the TEN, and not on the engine. Real savings in comparison with the following type is 2-5%.

View # 2. Innovative and Compact Inverter

Inverter engines began to equip Washing in 2005. Development of this variety belongs to the company LG, for a long time innovation provided the manufacturer leadership in the market.

Later inverter engines began to use samsung, bosch, aeg, whirlpool, haier.

The inverter is embedded in the drum of the washing machine, is a cover with permanent magnets (rotor) and climbing with coils (stator)

What is the feature of the design? In the absence of a collector-brush node and direct drive. Such an engine is installed directly to the drum and costs it in its work without a drive belt.

Anchor in it is assembled on magnets, the voltage is fed to the stator winding in the converted inverter, so the speed of revolutions can be adjusted and monitored.

  • simple and compact design;
  • economy due to the absence of the need to spend electricity to overcome the friction force in the collector-brush node;
  • almost silent;
  • There are no fast wear elements (brushes, belt), so long service life;
  • Low vibration level during spinning;
  • Ability to set a greater speed for spinning.

In some models, the machines with the inverter have the ability to adjust the drum rotation modes. This advantage of the manufacturer LG provides 6 Motion technology. But such washers are more expensive, and the repair costs it was not suiced due to the price of components.

View # 3. quiet and simple asynchronous

Such engines are two- and three-phase. The first model refers to the category of outdated and in the XXI century it is almost everywhere removed from production.

The second can be found in the early stroits of Bosch, Candy, Miele, Ardo. The asynchronous engine rotor is located at the bottom of the washing, with the drum connected by the belt, so they work at the same time.

The design of the asynchronous engine of the washer includes a rotor rotating drum, and a fixed stator. Torque is transmitted using a belt

In the care of an asynchronous engine unpretentious. the main task of the user is to a timely replacement of bearings and motor lubrication.

But there are flaws in it. Because of its principle of work in its characteristics not to find high power. The torque can be weakened at any time, the drum will cease to perform complete turns, the wash quality will deteriorate strongly.

And one more feature. electrical strokes are complex in management. With all its advantages, an asynchronous engine has shown in the fly, the main competition in the market occurs between inverters and manifiers.

Comparative analysis of models

Data on the type of engine and drive can be found from the passport of the machine. This information is obliged to own and consultant. You can pre-compare which of the engines is better for each list of consumer requirements. But first, let’s look at the fraudulent maneuvers of manufacturers of a type of engine.

Parameter Lack of rubbing parts in the inverter. It is not true, bearings in the mechanisms of the same amount, but there are no brushes in it.

But how many brushes serve that the collectors buyers are so frighten? 10-15 thousand. hours or up to 15 years of work in daily mode for 2-3 hours a day. At the same time, the guaranteed service life of the machine itself is 7-10 years. Yes, and the brushes are about 5 dollars. In the inverter washer, as in the collector may require replacement of bearings.

Statistics of repairs of styralic shows that the replacement of the brushes than the heating element, the bearings or the electronic unit is much less likely, and the cost of replacing the brushes below

Parmattetre Noise. Yes, the “brush” engine is more noisy, but the inverter also gives a characteristic squeak. The main sound is still not a motor, but a pump paired with a drum. During spinning the inverter and beeps, reminding mosquito.

Compare engines

Inverter Engine Type. Korean Development. It was used long ago, initially assumed for microwave ovens and air conditioners. But with the submission of world brands Samsung and LG, since 2005, the engines began to be embedded in washing household appliances, to increase its resource saving and reliability.

The principle of operation of the inverter engine is as follows: when the engine is rotated, a frequency converter is created, referred to as inverter. Here there is a transformation of the alternating stream into a constant, so when you exit you can see the current required frequency. This procedure makes it possible to accurately adjust the speed of the motor torsion and maintain the optimal amount of its turns.

The inverter motor for the machine-machine differs from the collector engine of the structure. it is not equipped with the brushes drunk on each other, but supports rotation using an electromagnetic field.

What criteria are guided by purchasing?

Before buying a device with an inverter engine, pay attention to a number of other technical parameters:

  • Energy Efficiency class. The higher the letter notation and the number of advantages, the most optimally the device works
  • Spin speed. New cars can accelerate up to 1600./ Min
  • Capacity. For a family of 3-4 people, the unit will suit 5-6 kg of dry linen
  • Functional. Models are equipped not only by universal options, but also additional programs
  • Security. This criterion is better not to go around. It is better to choose the washes with leak protection, display lock and imbalance control

Compare with other motors

Total distinguished three types of engines used when assembling washing machines. We will consider them all and comparable to each other.

  • Collector. Such motors are a metal core, directly collector, brushes and drive belt. Brushes direct current to movable elements of the motor. Of the minuses, you can mark the volume of work and the periodic need to replace parts. Of the advantages. ease of operation and fast drum acceleration.
  • Asynchronous. These motors are positioned as an alternative to collector from the point of view of smaller noise, however, there are many additional elements to use them.
  • Inverter. High-tech motors capable of combining high quality washing, efficiency of consumption, ease of work and reliability. At the same time, they practically do not make noise and do not require additional. service and dop. Devices.

Asynchronous engines will now almost not meet, but the machines with collector and inverter engines are sold almost in equal shares. If the engine type is fundamental for you, be sure to specify this information.

Inverter Engine

Inverter engine in a washing machine. a new generation engine. It appeared in 2005 in the LG technique and for a long time provided her to the market advantage. Now this type of engine applies to wider. it began to use the Samsung, Whirlpool, Aeg, Haier, Bosch brands.

This engine, as well as the collector, includes the stator, but the collector-brush node is missing in it. Therefore, the inverter engine is called direct drive engine.

What does the direct drive mean in a washing machine? The inverter engine is attached directly to the drum and does not need a belt for transmitting torque.

Direct drive washing machine has such advantages:

  • Relatively simple design;
  • Compactness;
  • High efficiency due to the fact that it is not necessary to overcome the power of friction of the motor and brushes. It provides fewer electricity consumption;
  • Serves longer due to the fact that there are no quickly wearing parts (belt and collector-brush knot);
  • Less noise;
  • The lower level of fluctuations and vibrations of the machine during washing and annealing;
  • The ability to press underwear at high speeds;
  • Ability to adjust various drum rotation modes (6 Motion technology in LG machines is built on this advantage).
  • Higher cost compared to other types of engines;
  • For the repair of such an engine, more expensive components are needed, so the cost of its repair will be higher.

Asynchronous electric motor

At the heart of the incomplete electric motor also lies the stator and rotor. The first remains still and performs the magnetic circuit, and the second reacts to the generated magnetic field, starts to rotate and spins the washing drum. However, in the process, the motor cannot synchronize with the speed of magnets and moves, a little behind them. Hence the name “Asynchronous”.

On washing machines there are two types of asynchronous type motors: two- and three-phase. Since 2000, since 2000, almost completely supplied the first due to their compactness and greater power.

Asynchons have the following advantages:

type, motor, washing, machine
  • Simple motor design, rarely failing;
  • high maintainability (due to affordable and cheap components);
  • low engine cost;
  • relatively low noity.

As for the shortcomings, the main one is the large size of the motor, which does not allow the use of asynchron in compact and narrow automata. Also, the minuses include the need for periodic repair of the system: lubricating pistons and replacing bearings. Do not shove such engines and efficiency due to low efficiency and complex control of electric circuits.

Asynchronous electric motors are found only in low-power budget models, small capacity and limited functionality. Otherwise, the motor will not cope with the load.

What is important when choosing a washing machine

The inscription “inverter” in the characteristics is not a guarantee of good purchase. The machine can yield to analogue with a standard engine (for example, asynchronous). Much depends on how the manufacturer implemented the model: what technologies used what scheme, components, processor, how high-qualityly collected it and so on.

The inverter in many cases reduces the noise level, or rather adjusts the revolutions and allows you to save on electricity, but as a result, the unit must qualitatively do two things: washing and pressing underwear. The question, with what accuracy the drum is spinning, is not the main.

What to watch when buying a washing machine, we wrote in this article. Here we will repeat the key abstracts:

Download Type: Horizontal or Vertical. It depends on the space in the apartment where you are planning to put the washer. Vertical sacks more space.

Capacity of the drum, as well as the size and dimensions of the device. For a large family (parents two children) are suitable for lifting capacity from 8 kg. Also consider that the weight of dry and wet linen manufacturers indicate separately.

Energy Efficiency class. It is better that it is a and above. this will allow you to further save on electricity

Additional functions. For example, in Haier machines, it includes automatic washing of glass and hatch cuffs (Smart Dual Spray), clothing processing steam (Steamfresh), water disinfection Ultraviolet (UV) and AutoVing (Auto Weighing).

Constructive features. For example, a special shape of the inner surface of the drum (Pillow) for gentle washing of delicate things.

Price. Pay attention to the discounts and remember the installation and configuration. some sellers take money for it additionally. Haier is free for separately standing washing and dishwashers.
