Control Algorithm Integrated FEM Based Starting Capability Analysis of Induction Motor and PMSM for Electrical Vehicle

With the development of technology, different types’ motors and control strategies are used in motor system for electric vehicle. Their starting capability are different according by motor types, control strategies and operating temperature. As a comparison, we analyze the starting capability of PMSM and IM in this paper. A 2D FEM integrated with control algorithm is applied to simulate the different working conditions for these motors, the starting capability with different control strategies are compared. Experiment results are consistent with the simulation results. The results show that the two motors have different maximum torque under the same protection current, and the design method described in this paper can be used as a reference for the design of electric vehicle drive motor.
