摘　　要：为了进一步降低电机的转矩波动,针对24槽10极六相永磁同步电机提出了一种定子采用非对称槽孔,转子采用非对称磁障相结合的非对称结构,通过有限元软件对电机的输出平均转矩、齿槽转矩以及空载感应电动势等性能进行分析计算。结果表明,新型非对称结构能进一步降低转矩波动,并且电机的总体性能也能得到小幅度的提升,验证了该新型非对称结构的有效性和正确性。为了改善电机的性能,以齿槽转矩和输出平均转矩为优化目标,对电机进行优化设计。结果表明,对电机的参数进行优化能有效地改善电机性能,验证了优化方法的有效性和有限元分析的正确性。In order to further reduce the torque ripple of the motor, for the 24-slot 10-pole six-phase permanent magnet synchronous motor, an asymmetrical slotted stator is proposed for the stator, and the rotor adopts an asymmetrical structure combined with asymmetrical magnetic barriers, the motor is controlled by finite element software, the output average torque, cogging torque and no-load induced electromotive force are analyzed and calculated.The results show that the new asymmetric structure can further reduce torque ripple, and the overall performance of the motor can also be slightly improved, which verifies The effectiveness and correctness of the new asymmetric structure.in order to improve the performance of the motor, the cogging torque and the average output torque are the optimization goals, and the motor is optimized.The results show that optimizing the parameters of the motor can be effective The improved motor performance verified the effectiveness of the optimization method and the correctness of the finite element analysis.
