摘要：
This paper describes a technique for minimizing the detent force using the Finite Element Method. The detent force of the whole stator core is the total of tao magnetic forces arising at both side edges of a stator care. Computed results show the phase difference between the tao magnetic forces. Therefore, we can cancel out the tao forces by adjusting a stator length to minimize the detent force. The stator with the smooth formed edge shape is also contrived to reduce the detent force in the practical use. The detent force of this model is successfully minimized by proposed method.
