This paper presents a design method for improving the power density using the reluctance torque of Interior a permanent magnet synchronous motor(IPMSM) for Plug-in Hybrid Electric Vehicle(PHEV). First, the different of the d-axis inductance and the q-axis inductance is increased in order to increase the power density of the motor. And Through the EL map, the characteristics of the motor according to the range of the inductance and the back electromotive force are calculated. And the stability is verified by the rotor structure analysis at the maximum speed. We select the bridge thickness, the permanent magnet angle, and the distance between the 1-layer and the 2-layer as the design parameters, and proceed through the optimal design through the reaction surface method. Finally, the electrical characteristics and mechanical stability of existing models are discussed.
