| Abstract: | In this paper, to reduce cogging torque, an method which was based on energy method and Fourier expansion is proposed to obtain the expression of cogging torque, which can express its relation with design parameters. Being based on this expression, the rules of the effect on cogging torque is proposed. The validity of the proposed rules is verified by finite element analysis. |
