Abstract

This paper presents an optimization design and analysis of a 30kW V-type interior permanent magnet synchronous motor (VIPMSM) with distributed winding used in electric vehicles using finite element analysis (FEA). In order to reduce cogging torque, increase efficiency and avoid using winding skew, 48 slots 10 poles V-type fractional-slots IPMSM is selected in the design. Structure optimization including stator and rotor structure size, permanent magnet size, magnetic bridge and air gap length are analyzed and simulated by ANSYS Maxwell 2D FEA. Torque characteristic of VIPMSM and circle diagram are analyzed to better understand the operation of VIPMSM. The constant torque and constant power performance are considered in the motor design. The final comparison results indicate the prototype essentially satisfies the design specification.
