摘　　要：永磁游标电机有低速大转矩运行、直接驱动等优点,在保证转矩密度的同时降低转矩脉动是该类电机优化的主要目标。以内转子永磁游标电机为研究对象,利用敏感性分析确定优化因素,采用多目标正交优化、粒子群算法对该电机进行了优化,提出了二者相结合的正交-粒子群优化算法。利用有限元法对上述3种优化结果进行仿真,结果表明,该方法解决了正交优化精度不足和粒子群优化计算量大的问题;优化后使电机电磁转矩增加8.5%,转矩脉动减小8.23%,提升了电机的性能。Permanent magnet vernier motor(PMVM)has the advantages of low speed and high torque operation,direct drive and so on.The main goal of optimization is reducing torque ripple while ensuring torque density in this type of motor.Aiming at the internal rotor permanent magnet vernier motor,the optimization factors were determined with the sensitivity analysis,then the multi-target orthogonal optimization and particle swarm optimization(PSO)are adoptedto optimize the rotor permanent magnet cursor motor,and the method of orthogonal-particle swarm optimization algorithmis proposed to improve the orthogonal optimization precision and the computationally complex problems in the particle swarm optimizationis solved.The three optimization results are simulated and compared with the finite element analysis.The results show that the present method solves the insufficient accuracy of the orthogonal optimization and the large computation of the particle swarm optimization.After optimization,the electromagnetic torque of the motor increases by 8.5%and the torque ripple decreases by 8.23%,which improves the performance of the motor.
