What's the difference between washing machine motors?

Motors are to washing machines what engines are to cars. The quality and performance of the motor determine the performance of the washing machine, which is a very core technology. At present, in the washing machine market, motors can be roughly divided into belt (ordinary motor) and belt-less (variable frequency direct drive). Next, let me tell you the difference:

Direct driver

For example, several ultra-quiet washing machines of Haier have cooperated with Fisher & Paykel, a national treasure brand in New Zealand, and replaced traditional motors with direct-drive inverter motors. The biggest difference from the ordinary traditional motor is that it has no belt and is directly connected with the washing tub, which saves the connecting mechanism such as reducer and gear box. It ensures that the deviation of the inner cylinder is very small, the stability of the machine operation is greatly improved, and the working state of ultra-low vibration and ultra-quiet is realized.

Traditional electricity

The kinetic energy generated by the motor of the washing machine is transferred to the washing tub through the belt. Because the friction generated by the long-term high-speed operation of the belt will loosen, the motor driven by the belt may fail. During the rotation of the belt, the motor will make a lot of noise and "dance" because of the unstable rotation.
