The world's first washing machine was born in 1858, made by Hamilton Smith in Pittsburgh, USA. After 160 years of development, the washing machine has been able to fully serve the cleaning of household clothes and become an essential part of home life.
The style and function of the washing machine are becoming more and more abundant, which brings more choices for the user and also adds to the difficulty of purchasing. Then how to choose the washing machine, the key is to look at the washer motor, since the washer motor is the key!
The role of the washer motor for the washing machine is like the engine for the car. The quality of the washer motor directly affects the final washing quality and experience of the washing machine. Most of the washer motors on the market today use conventional belt motors. The kinetic energy generated by washer motor is transmitted to the washing drum by a belt. Although the transmission method is low in cost, its biggest disadvantage is that the vibration is large and the operation is unstable. Since the drum and the motor are not on the same shaft, the inevitable vibration will occur at high speed of the motor. Over time, the internal components are loose, which in turn causes the washing machine to be unstable. Lightly, noise will affect the family life, but the washing machine will produce a "dancing" phenomenon or even a body explosion accident, leaving a hidden danger to personal safety.
Some washing machine adopts a new generation of high-efficiency DD frequency conversion direct drive motor independently developed. Unlike conventional belt motors, this type of motor requires a motor and an inner barrel to be connected by a belt and carbon brush. The DD variable frequency direct drive motor is directly connected to the washing drum, eliminating the need for a transmission structure such as a gear belt in the middle.
