YCZQ blower special three-phase asynchronous starting permanent magnet synchronous motor

Patent No.: ZL202020542983.2 

Characteristics: Different from the design philosophy of the traditional asynchronous starting permanent magnet synchronous motor, it changes the number of effective series conductors in the starting process of motors in accordance with loading characteristics of the direct-drive fans, to improve the pull-in synchronous torque and make the fan operated at the pull-in synchronous speed. 

Advantages: 

The small-power asynchronous starting permanent magnet synchronous motor could directly drive and operate the fans synchronously without variable frequency drive.
