摘　　要：在综合了各种车用电动机的性能特点后,研制出一种定子铁心槽为斜槽的特殊结构的混合励磁永磁同步电动机。仿真结果表明:定子斜槽混合励磁永磁同步电动机可以有效减小异步附加转矩,使电动机转矩脉动大大降低,电动汽车运行更加平稳舒适。同时,由于混合励磁永磁同步电动机具有励磁磁场可调节的特点,所以解决了弱磁调速困难的问题,在很宽的范围实现了恒功率调速。After combining all the performance characteristics of various types of motor vehicle, the hybrid ex- citation permanent magnet synchronous motor with stator skewing was developed. Simulation result shows the hybrid excitation permanent magnet synchronous motor with stator skewing can reduce the additional asyn- chronous torque effectively and reduce the motor torque ripple greatly, and moreover, it can make electric ve- hicles run more smoothly and comfortably. Hybrid excitation permanent magnet synchronous motor field excita- tion characteristics can be adjusted to solve the difficult problem of the weak magnetic timing and realize the speed regulation in a wide range under the condition of constant power.
