永磁同步轮毂电机设计及其弱磁控制研究

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。

Research on Permanent Magnet Synchronous in-Wheel Motor Design and Flux-Weakening Control

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 ...
