Abstract

The finite element method and analytical method are combined to optimize the ratio between rotor slot width and rotor tooth pitch, in order to reduce the cogging torque in line-start permanent magnet synchronous motors. Based on energy theory equation and Fourier transform, the simulation analysis results are in good agreement with the proposed method.
