Abstract

In this paper, finite element analysis is used to analyze the torque of Permanent Magnet Synchronous Motor (PMSM) of electric vehicle. Firstly, a 2D model of the PMSM is made. By forming magnetic field lines and flux density distribution of the PMSM with no-load condition, the accuracy of the model can be verified. Secondly, torque fluctuation curve of the PMSM with rated load is analyzed. It shows that the torque of the motor meets the stability requirements. Finally, by setting different current stimulations, analyzing the change of the motor output torque, it can be concluded that the relationship between motor torque and current amplitude is nonlinear, which lays a foundation for the operation optimization of the PMSM used in electric vehicle.
