This paper dealt with design to improve power density of the permanent magnet synchronous motor (PMSM) for the hybrid electric vehicle (HEV) and to reduce mass of permanent magnet (PM). It can be achieved from guaranteeing Q-axis flux path which is related to the increase of reluctance torque and from increasing turns of stator winding from introducing closed slot design. Also, power density is advanced from decreasing stacking length. The permanent magnet is designed considering heat generated by losses and reaction field of D-axis because motor in HEV is placed with an engine which generates the high heat. This paper is verified by comparisons between existing model and modified model based on analysis and experiments.
