The Taguchi method is adopted to optimize the structure of high-speed permanent magnet synchronous motor for an electric vehicle with rated speed of 5000 r/min and rated power of 60 kW, in an attempt to improve the electromagnetic performance and efficiency of high-speed permanent magnet synchronous motor for electric vehicles. By analyzing the effect of the optimization variables on the motor iron loss, the average electromagnetic torque and the torque ripple, this paper obtaines the optimal optimization solution. The iron loss model of motor is established, and the Sine-equivalence method, harmonic-component method and FEA method are used to calculate the iron loss of stator respectively. Finally, the rationality of iron loss analysis method of the motor is verified by comparing calculated results and measured results.
