摘　　要：采用有限元法设计永磁同步轮毂电机,对影响其性能的气隙磁密谐波和齿槽转矩进行优化,降低了谐波损耗和力矩波动,达到速度高、控制性能好、功率密度高的特点,提高了轮毂电机的性能。并且对轮毂电机进行弱磁控制,扩大其调速范围并且增大其扭矩,最后试制了一台内置式交流永磁同步轮毂电机样机,并对性能进行了测试,满足设计要求。Designed Permanent magnet synchronous in-wheel motor Adopt finite element method in. Optimized the air-gap flux-density harmonics and the cogging torque parameter, which affected the performance of in-wheel-motor. Reduced the harmonic losses and torque ripple, so high speed, good control performance and high power density characteristics had been realized, and the performance of in-wheel-motors had also been improved. Expanded its speed and torque range using flux-weakening control in the in-wheel-motor. At last a inner in-wheel-motor prototype had been made, then testing its performance, the results illustrate the performance of the prototype can meet the design requirements.
