The inverter engine, created by the engineers of the Korean concern LG in 2005, brought the production of washing machines to a whole new level. Compared to its predecessors, this motor has better technical characteristics, it is more durable and therefore, it lasts much longer .That is why inverter engines are so rapidly gaining popularity, and the production technology of these units is being adopted by an increasing number of manufacturers.
Features of the
The main feature of this type of motors is the availability of a special device - an inverter( frequency converter), which regulates the speed and frequency of the drum rotations, converting the current from DC to AC.This allows you to control the operation of the mechanism with the utmost precision.
In conventional engines, the moving part of the motor - the rotor( also referred to as the "anchor") is fed through the brushes: a magnetic field appears in the windings of the rotor and it starts to rotate. The speed of its movement depends on the voltage in the network.
The rate of rotation of inverter motors is determined by the voltage that is first converted by the inverter, and then fed to the stator. That is why the work of such engines can be controlled to the smallest detail.
Pros
- Inverter motors operate almost silently. This indicator is especially important for families with children;you can start washing at any time, without fearing to wake the baby.
- In such motors there are no parts that can quickly fail due to the fact that during operation they are subject to intense friction. This is a guarantee that the unit will last longer, than its asynchronous and collector "colleagues".
- For the same reason, inverter motors have higher efficiency, and energy savings of up to 20%.
- Inverter-type motors very precisely control the movements of the drum, which ensures strict compliance of washing with the declared mode.
- Inverter machines are capable of pressing laundry at high speed.
Cons
The main disadvantage of engines of this type is their high price and high cost of repair in case the unit fails.
Should I buy?
As you know, everything in the world is relative. To understand whether to choose the inverter car, look at it from another perspective:
- Do you need silence when washing? It is noted that machines with direct motor drive work more quietly than inverter-type engines. The inverter produces very specific sounds, similar to squeaks and howls. In addition, the main reason for the loud operation of the equipment is not the engine, but an activated nanoscrew and spinning drum.
- Is it real saving? In fact, the main expense of electricity is not on the engine, but on the work of the heating element. So, in fact, you can save only 2-5% of electricity.
- Are you interested in durability? Speaking about the lack of parts in the unit, subject to friction, the manufacturers are a little bit off the soul: the bearings are in any motor, and the number of them is approximately the same. The above statement applies mainly to brushes that apply tension to the armature winding. Indeed, they do not exist in the inverter motor. However, the period of wear of these parts is about 10 years, and the cost of their replacement varies within 2-3 cu.
The inverter type engine can last more than 15 years, but are you sure that you do not want to change the model of the washing machine before?
- Intense spin - good? When spinning at high speed, the laundry becomes almost dry, but the fabric is damaged faster and tears.
- Why do you need accuracy of revolutions? The main requirement for washing equipment is its ability to wash laundry. And what kind of turns it will be to make a car, it's not so important.
Specialists recommend that when choosing a washing machine, first of all, pay attention to its functionality. The inverter motor alone does not guarantee that the machine will be flawlessly washed.
