The use of washing machine motor inverter, the buyer has a question, and what better to choose a washing machine with an inverter motor or simple.
Classic motor: anchored by brush fed the current passing through the armature winding creates a magnetic field which rotates the motor armature. As the stator motor can be permanent magnets or windings.
Inverter motor: it is assembled on the motor armature magnets, the speed depends on the voltage applied to the stator winding voltage is applied not directly from the network and is converted by the inverter. This makes it possible to control the desired engine speed.
Try to understand and cut advertising from reality. For example, consider the benefits voiced by producers for inverter motors.
The lack of friction parts as a consequence of a more durable engine.
This statement is not entirely true, rubbing parts (bearings) in the same amount in the engine. The difference, no carbon brushes, which is fed to the motor armature current. They rub against the motor armature and gradually wear out, but their life span is designed for 10 000 - 15 000 hours, complete wear them come in 10-15 years of the washing machine. Assuming the use of a washing machine for 3 hours a day, and it will agree not small. And note the specified service life of the washing machine of 7-10 years. And the cost of carbon brushes $ 2-3.
So that assertion engine wear (carbon brushes) can not be taken as an advantage.
Yes motor without carbon brushes emits less noise, but compared with the usual (no sparking between brushes and anchor), but he utters howls and squeak (so runs the inverter). An example of an inverter motor, urban electric transport. The main noise of the washing machine emits no engine and the pump and the drum when spinning the laundry. When spinning the engine's inventory may make a characteristic squeak squeak of a mosquito resembles. Very much not like a squeak.
Therefore, you will not notice much of a difference between the noise and the inverter ordinary washing machine. For some owners of washing machines inverter contrary seem noisier.
Provides more precise engine speed
Yes, in an ordinary electric motor turns depends on the external network, the inverter is also there but not as pronounced.
In the washing machine does not need the exact observance of the engine speed.
Inverter drive more cost 15-20% less electricity it consumes, but not always. In it merely more precisely regulated by the momentum and not to waste electricity. Example by loading the washing machine 2kg. laundry machine with ordinary motor will spin the engine as much as possible, the inverter is adjusting the momentum will not untwist the engine as much as possible, it will stabilize the turnover, as a result consume a little less energy.
But considering that in the washing machine main power consumption is not the engine, 80% of energy is spent on heating water. Actual energy savings will amount to at best 2-5%. And if the washing machine load of 50% of the maximum weight of laundry.
So what is the best engine in washing machines, some of them are identical in operation, but manufacturers have recently bet on the inverter motor. Therefore, more and more washing machines comes with an inverter motor, manufacturers often do not even stipulate in the characteristics of the engine type.
