In this paper, the generation mechanism of cogging torque is analyzed mathematically. Based on the pole-slot combination method and the teeth notching method, suppression of the cogging torque is discussed. Two-dimensional finite element models of the PM motor with different pole-slot number are established, transient simulations are performed, and the cogging torques relating to different number and dimension of teeth notches are analyzed. The results verify the feasi-bility and validity of the proposed theory and analysis method．
