Development Trend of Washer Motor I

  •  


    With the development of society, Washer Motor continue to develop in high power density, energy saving, environmental protection (low noise), which also determines that variable speed motors will become mainstream motors. In particular, variable frequency motors and brushless motors are favored by more and more users due to their advantages of reliable structure, convenient control, high efficiency and low noise.


    With the continuous improvement of people's consumption level and quality of life, the demand for environmentally-friendly and intelligent washing machines is also increasing. As the main driving force of washing machines, the performance of washer motors must be continuously improved. At present, there are two main types of washing machines popular in the domestic market: pulsator and drum type washing machines.


    The motor used in the pulsator washing machine is mainly a single-phase induction motor, a few inverter motors and brushless motors are used, and the drum washing machine is mainly a series motor, in addition to a variable frequency motor, a brushless motor, a switched reluctance motor, etc. In general, it can be divided into two categories: fixed speed motor and variable speed motor. Here is a brief introduction to the above motor.


    First, fixed speed motor


    Fixed-speed motors are basically single-phase asynchronous motors with capacitive operation. They are induction motors and can be divided into single-speed motors and two-speed motors.


    Single-speed motor: There are two phase windings perpendicular to each other in the stator. One phase is connected to the power supply through a phase shifting capacitor. The rotor consists of a core and a squirrel cage. There is no direct connection between the stator and the rotor. The stator winding After being energized, a rotating magnetic field is generated, and the rotating magnetic field induces an induced current in the rotor cage, and the two interact to generate an electromagnetic force. It has the advantages of simple structure and low cost of the induction motor, and the running performance is also good, but the starting performance is slightly poor and the speed cannot be adjusted. Single speed motors are mainly used on pulsator washing machines.


    Two-speed motor: The principle is the same as that of single-speed motor. The difference is that there are two sets of different windings on the stator of this type of motor to generate different speeds. If you interested in Nanyang Motor, please feel free to contact us any time:
