Its surface quality directly affects the motor's performance and lifespan. An unpolished rotor surface is rough, and friction can cause metal debris to fall off, significantly impacting the motor's performance and lifespan after installation. Therefore, polishing is necessary during manufacturing to improve the smoothness and flatness of the rotor surface, thereby extending the motor's lifespan.
