Abstract：To solve the problem of torque ripple, max well tensor method and three-dimensional finite element analysis method were used for theoretical analysis in this paper. In this paper, from the prospect of optimizing rotor tooth profile, a new rotor tooth shape with pole shoe（T-type）was adopted. This kind of rotor tooth could reduce the radial force wave integral area to achieve the purpose of decreasing the torque ripple. Maxwell tensor method was used to compare radial and tangential force wave off our different tooth profiles in air gap. Experiment results verified that adopting three-dimensional finite element analysis to calculate the motor flux-current characteristics was correct. The influence of variation of T-type rotor tooth structural parameters on torque ripple was conducted based on FEA method. It is proved that the T-type rotor tooth could increase tangential force wave, reduce the value of the radial force wave as well as torque ripple.
