Performance Evaluation of a 60kW IPM Motor for Medium Commercial EV Traction Application

Abstract

Abstract. This paper presents the design and performance analysis of a 60kW Interior PM (IPM) synchronous motor used as traction drive in a medium commercial electric vehicle (EV). The 2D time-stepping finite element method (TS-FEM) simulation model of the IPM motor is built by using 2D Maxwell software. The geometric structures of the IPM motor are optimized, and the operational performances of the IPM motor running at full speed range are investigated. Finally, the experimental platform of the prototype motor and its controlling system are set up. The performance comparison of the experimental results and simulation results of the IPM motor running in various operating mode are reported. All the results show that the designed IPM motor can match all requirements of the medium commercial electric vehicle driving applications.
