永磁游标电机的多目标正交-粒子群优化
Multi-objective Orthogonal Particle Swarm Optimization of Permanent Magnet Vernier Motor
摘要
Abstract
Permanent magnet vernier motor(PM VM)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 insuffiicient 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.关键词
