What is an inverter washing machine

Inverter washing machines are a class of innovative household appliances, the main difference of which is the inverter motor.

For the first time such a machine was produced by the South Korean brand LG, since then the demand for it began to grow, and today, in any household appliance store, consultants will primarily recommend an inverter washing machine.

With inverter motors, such world brands as Panasonic, Sumsung, Bosch, etc. began to make washing machines. The popularity of this technique is growing every day due to the Efficiency during operation, as well as the high quality of washing.

Principle of operation

Important! The inverter motor differs from the collector motor in that it does not provide for the installation of brushes and there is not a belt drive type of drive, but a direct one.

Due to the fact that an inverter (frequency converter) is provided, the required frequency of the electric current is achieved. Because of this, the most accurate speed control of the washing drum is carried out.

The principle of operation is to invert current. The engine speed is controlled by a frequency converter. The voltage is immediately converted by it, only after that it enters the stator. This feature of the inverter motor allows you to carefully control the entire washing process. The brushless motor design provides spinning at very high speeds, which makes the laundry almost dry after washing.

The selection of the desired program is carried out mechanically or electronically. The first option involves the use of mechanical controls, or a more modern option - buttons that extend the life of the control panel. The second option is much more convenient, because you need to press a single start button, and the machine will do everything for you, starting from weighing the laundry and ending with determining the time required for washing.

Benefits

The main advantages of inverter washing machines include:

  • The service life of the equipment is much longer;
  • Due to the fact that there are no brushes that rub against each other, uninterrupted operation of the motor is ensured and wear is prevented;
  • Improving the quality of washing. Since the vibrations of the machine are minimized, as a result, the linen is better distributed inside and thoroughly cleaned;
  • Profitability of work due to reduced energy costs;
  • The spin phase is carried out at high speed;
  • Erases with a minimum of noise;
  • The inverter motor precisely provides all the specified parameters.

Disadvantages

Before you purchase a particular version of a washing machine for the home, you should carefully consider and weigh not only the pros, but also the minuses. Although inverter-type machines have few drawbacks, they should be known.

The disadvantages include:

  • High cost when compared to conventional machines.
  • Before choosing a technique, you always need to consider the case of breakage, the possible replacement of parts. And in the case of an inverter machine, these components are not cheap.
  • Little is mentioned, but the inverter motor is also characterized by increased sensitivity to voltage drops.

Inverter motor in the washing machine what is it

The main distinguishing feature of the inverter motor is the presence of an inverter, due to which the speed and frequency of rotation of the drum are carefully regulated, and the current is converted from direct to alternating current. The inverter motor consists of a fixed part with a set of coils, which is attached to a plastic tank and a movable part - a flywheel, in the case of which magnets are located. A plastic adapter (insert) is provided in the middle of the flywheel to eliminate the possibility of a magnetic field affecting the drum of the washing machine.

The speed of rotation of the inverter motor is determined by the voltage, which is first converted by the inverter, and then fed to the stator. According to the declared characteristics from manufacturers, invertorenginewill serve about 15 years.

Inverter drive in the washing machine what is it

The washing machine is also selected according to the type of drive. It can be a belt or direct inverter.

The developers of the inverter drive decided to abandon the outdated technology with the belt by combining the drum and motor into a single unit. This has improved the workflow.

Due to the fact that the motor became attached directly to the drum shaft, the whole system turned out to be dynamically balanced. The resulting system was calledDirect drive or inverter motor with direct drive.

There are not so many models with direct drive in stores, they are all from the LG brand, Samsung also has several models, plus another 1-2 manufacturers and that's it. Thanks to the introduction of a direct inverter drive, modern washing machines now better control the speed, direction of rotation and accuracy of the drum.

Important! The motor is fixed on the same axis as the drum, this helps to reduce vibration and noise. The mechanical load and wear of parts are also significantly reduced with direct drive.

Noise level and power consumption

Although for most buyers, the noise level is not so important when evaluating different models before buying. But there are also those users for whom complete silence during washing is fundamentally important. After all, there may be an option when the child is frightened by noise and hum, does not fall asleep. Therefore, pay attention to inverter washing machines that operate almost silently, without noise and vibration.

Important! Mostly the noise accompanying the washing is not made by the motor itself, but by the pump and drum, which rotates intensively, especially during the spin cycle. The inverter motor runs without hum, but it can make certain sounds.

Regarding the saving of electric energy, this factor also attracts the attention of buyers, and according to observations is about 20%. In addition, inverter machines have a useful auto-off function, which also involves energy savings. Due to the fact that brushless motors are used, the spinning of the wash occurs at a fairly high speed, the housewives get almost dry laundry.

In addition to the characteristics of the design itself and technical features, there are also nuances of operation. Inverter washing machines should be installed exclusively on level surfaces, even without inconspicuous slopes. Powder or other detergent should be used exclusively with the mark “automatic”. As with any other washing machine, you need to give it a little rest, and not start the next wash immediately after the end. It’s best to wait a couple of hours.

Also, before buying an inverter washing machine, carefully familiarize yourself with all the characteristics, and take into account all the pros and cons. Not all benefits may be important to you. For example, a more thorough spin threatens that things will wear out faster and lose their original presentation. Therefore, first of all, decide for yourself whether you want such an innovative machine or prefer a regular one.
