Optimization design and analysis of a 30kW interior permanent magnet synchronous motor used in electric vehicles

In the paper, the optimization design and analysis of a 30kW interior permanent magnet synchronous motor (IPMSM) used in electric vehicles are fulfilled by finite element analysis (FEA). In order to satisfy good control performances, low cost and high reliability, Simulation and experimental verification of the prototype are compared deeply, and the final comparison results indicate the prototype essentially satisfies the design specification.
