Description
Technical Field

[0002] At present, the driving module of traditional pulsator washing machines on the market is mainly composed of an asynchronous motor, a reduction clutch and a belt. The asynchronous motor outputs power, and the belt transmits torque to the input end of the reduction clutch. After being decelerated by the reduction box, the power is output to the pulsator from the output end. This structure has the defects of low transmission efficiency, high energy consumption, and high noise. To address these defects, a DC variable frequency direct drive motor can be used to replace the asynchronous motor, directly axially drive the input end of the reduction clutch, with higher transmission efficiency and less noise. In addition, the direct drive motor can be integrated with the reduction clutch into a modular product, which reduces the assembly defect rate and reduces costs.
