Abstract

This paper presents a rotor shape optimization of interior type permanent magnet (IPM) motor for cogging torque minimization and maximization of reluctance torque. In order to minimize the cogging torque, the optimal notches are put on the rotor pole face and the arc type pole face is applied. The variations of cogging torque and d-q axis inductions are analyzed by finite element method (FEM).
