| Abstract: | Cogging torque may cause torque oscillation and noise while motors running,which affects their performance indexes.Aiming at this problem and comparing with several common cogging torque reducing methods,the feasibility of reducing cogging torque with pole width modulation method was pointed out.The cogging torques of surface-mounted permanent magnet motor and pole width modulation permanent magnet motor were calculated separately by the model built with finite element method(FEM).The cogging torque experim... |
