Abstract :
In this paper, an interior permanent magnet synchronous motor (IPMSM) is proposed for electric vehicle (EV) traction system, which is required to be high efficiency performance and capable of wide constant-power operation under proper vector current control strategies. With the help of 2-D finite element analysis (FEA) and equivalent circuit method, with considering the limitation of battery voltage, an 80kW designed IPMSM is designed and then manufactured for test. The validity of presented motor design method and vector current prediction according to given control strategy is finally verified by test results.
