With the rapid development of today's economy, how to save energy has become a worldwide topic. Therefore, for the more and more popular washing machine, how to improve the efficiency of the motor used also appears more and more important. At the same time, with the continuous improvement of people's consumption level and quality of life, the demand for environmental protection and intelligent washing machine is also increasing, which is the main power motor of washing machine
More and more demanding. There are two main popular washing machines in the current domestic market: wave type and drum type automatic washing machine. Its basic principle is through no matter what kind of washing machine motor driven dolly tub (roller) rotation to produce water, again by the water and the dolly tub (roller) wash clothes, the force of different motor speed determines different dolly tub (roller) speed, is also determines the quality of washing and washing machine running status, such as noise, vibration, etc. Thus, the performance of the motor has a decisive impact on the performance of the washing machine. At present, the motors used on the wave wheel machine are single-phase induction motors and a few brushless motors are mainly series motors on the drum machine, and some are frequency conversion motors, brushless motors, switched reluctance motors and so on. Generally speaking, it can be divided into two categories: constant speed motors and variable speed motors. The following is a brief introduction to the above motors. 1. Constant speed motors Constant speed motors are basically capacitive single-phase asynchronous motors, which belong to induction motors. They can be divided into two categories: single-speed motors and two-speed motors.
