The Approach for Reducing Cogging Torque of Interior Permanent Magnet Motor Using The Design of Experiment

실험계획법을 이용한 매입형 영구자석 전동기의 코깅 토오크 저감에 대한 연구

This paper proposes the optimal design method to reduce the cogging torque of the interior permanent magnet motor using the design of experiment. The slot opening. tooth tips and the pole arc/pole pitch are chosen as factors of the design of experiment in order to find optimal conditions of the interior permanent magnet motor. Finally, the cogging torque of the optimized motor compares with that of the original motor.
