Inverter washing machine: newfangled thing or a necessary assistant

An interesting new product in the world of washing machines became machines equipped with inverter-type motors. They are distinguished by improved technical parameters and are used in the production of most modern units. We will understand what is remarkable modern washing machine, and why you should pay attention to models with an inverter motor.

Features of models

Motors of the usual type work according to the following principle. The current flows to the rotor through brushes. The magnetic field that occurs in the rotor windings sets it in motion. The rotational speed is directly related to the mains voltage.

An inverter motor, unlike a motor in a conventional washing machine, does not have friction parts in the form of brushes.

Inverter is frequency converter. It converts alternating current into direct current, and then after such a change it can generate alternating current with the desired frequency level. Due to this, he is able to accurately adjust the speed and frequency modes of the drum.

Advantages and disadvantages

Consider the main advantages of using units with a frequency converter compared with conventional models:

1. Since there are no rubbing brushes, less energy is used to rotate the engine. Due to this efficiency increases. With less cost of the motor, reduced power consumption by 20%.
2. Durability of equipment. It does not require regular replacement of brushes that quickly fail during operation as a result of intense friction.
3. The noise level is lower, since there are no rubbing elements. Wash is almost silent. This is important for families with children, as it is possible to carry out washing without hindrance at any time, without worrying that the child will wake up from noise.
4. Immediately reaches the desired level of speed and frequency, and maintains it throughout the entire process of washing. Accuracy of controlling the movement of the drum in accordance with the set mode.In addition, spinning is done at high speed.

Such units are inherent and disadvantages:

• Such devices are more expensive than conventional units.
• In the event of a malfunction, you will need to spend a decent amount on repairs, as well as on the purchase of necessary components.

Pros and cons

Consider the voiced advantages of the device and try to understand whether there is a need to purchase just such washing equipment. Are all the above advantages inherent in machines with an inverter motor, or is it an advertising move?

1. First of all, we will consider a positive quality of the device, such as a low noise level. It is known that direct drive washing machines the motor is capable of washing much quieter than inverters. The sounds made by the inverter, more like squeaks and howls. The main noise during the washing process is not at all produced by the motor, but by the running pump and the drum in spin mode during rotation.
2. Above it was said about the efficiency of such devices, is this really so? Indeed, the power consumption is somewhat lower. However, it is important to consider that the main power consumption is not required for engine operation,and for the functioning of the heating element. Thus, there is energy saving, but it is no more than 5%.
3. Durability and lack of consumables, which must be regularly replaced - this is definitely an advantage of the devices. But if you think about it, it is primarily about brushes that are subject to friction. In fact, these parts in conventional machines can be used up to 10 years, and have a fairly low cost, so their replacement is not difficult.
4. The service life of inverter-type units may exceed 15 years. However, there is no guarantee that in such a long time there will be no desire to acquire a more modern and functional model.
5. Spin at high speeds is a dubious advantage, since with such an impact the fabric wears out much faster, is damaged and can tear. However, as a result of such a spin, the laundry really becomes almost dry.
6. Speed ​​accuracy is not as important as the manufacturers say. The main criterion for evaluating the operation of a washing machine is the quality of laundry.How and with what frequency of revolutions this will be carried out does not matter much.

Conclusion

Choosing washing equipment, you should be guided first of all. on the feature set.

A machine with an inverter motor is more durable and economical, produces less noise, and also complies with the required level of speed and frequency of washing in accordance with the mode.

The cost of such a unit is quite high, and in the event of a malfunction, costly repairs will be required. It is important to understand that the presence of an inverter-type motor does not give any guarantees of high-quality laundry. However, in conjunction with the necessary and useful features, such a device would be an excellent choice as a home assistant.
