초록

In this paper, the notch of teeth, the shape changing and skew of permanent magnet are used to reduce the detent force. And addition, overhang of permanent magnet is applied to increase thrust because thrust is decreased by skew. As the results, detent force is decrease greatly about 98(%). And, the ripple ratio of thrust is decreased from 11.34(%) to 0.25(%).
