Its surface quality directly affects the performance and life of the motor. The surface of the unpolished rotor is relatively rough, which may cause metal debris to fall through friction, which will greatly affect the performance and life of the motor after installation. Therefore, polishing is required during the manufacturing process to improve the smoothness and flatness of the rotor surface, thereby increasing the life of the motor.

[0003] A polishing device for generator rotor production is disclosed in a Chinese utility model patent with publication number CN220762189U, which includes a fixed frame and a rotor body. A fixing device is provided inside the fixed frame, and the fixing device includes two internal threaded rings. The arc surfaces of the two internal threaded rings are fixedly connected to the fixed frame. The internal threads of the internal threaded rings are connected with threaded rods. The ends of the two threaded rods close to each other are fixedly connected with round blocks. The arc surfaces of the round blocks are rotatably connected with the fixing rings. The ends of the two fixing rings close to each other are fixedly connected with connecting plates. Both ends of the connecting plates are fixedly connected with U-shaped plates. The outside of the rotor body is rotatably connected with a polishing rod. Both ends of the polishing rod are fixedly connected with round rods. The arc surfaces of the two round rods are rotatably connected with support plates. One end of the support plate is fixedly connected with a fixed block. The inner wall of the fixed block is fixedly connected with a driving motor. The rotating threaded rod drives the connecting plate to move. The connecting plate drives the U-shaped plate to move to fix the motor rotor. The driving motor is started to drive the polishing rod to rotate to polish the motor rotor.

After polishing, the staff is required to take out the polished motor rotor and then put in the unpolished motor rotor.
