A Study on the Low Cogging Torque of Brushless DC Motor

브러시레스 D\ulcornerC 모터의 코깅 토오크 저감에 관한 연구

In this study new design method with auxiliary slot on salient pole is proposed for the reduction of cogging torque which is the problem of corm type DC Brushless motor. And FEM(Finite element method) is adapted in trial motor which is designed by the method proposed in this paper. and learn the quantative characteristics of cogging torque. Comparing results of analysis with measurement it is porved that the proposed design has a propriety.
