In the past, the old-fashioned laundry used single-phase asynchronous motors. In recent years, with the continuous improvement of the functional requirements of washing machines, the production of  brushless DC washing machine motors manufacturers has also been applied in washing machines.

Generally, a low-noise flat DC washing machine motors is used without any mechanical deceleration and transmission device. The brushless DC motor directly drives the drum of the washing machine, and adopts stepless speed regulation. It runs at low speed during washing and high speed during dehydration, and the failure rate is very low. . At the same time, fuzzy control technology is adopted to improve its technical level. At present, the domestic market is gradually optimistic about the sales of such washing machines.

This type of motor generally adopts an external rotor structure, and the stator core is punched with material to make full use of materials. The length of the core: VM-DD1 is 26mm, VM-DD2 is 21mm, with 36 slots, using three-phase concentrated winding, star connection, The rotor has 24 poles and adopts ferrite permanent magnet material.
