Abstract
Aiming at the permanent magnet synchronous motor (PMSM) with rotor eccentricity fault, two-dimensional static and dynamic eccentric models of PMSM are established respectively based on the finite element software EasiMotor. Through the simulation and the Fourier transform, air-gap flux density and radial electromagnetic force are solved. Simulation results show that the rotor eccentricity is an important influence factor for PMSM used in electric vehicle, which can be reference for further research on rotor-eccentricity magnetic field.
