摘要 采用斜极结构消弱永磁驱动器的齿槽转矩,利用解析方法推导出具有斜极结构的永磁驱动器齿槽转矩解析表达式。采用Ansys有限元仿真和中心复合实验设计获取响应值,根据响应值建立斜极结构永磁驱动器的二阶响应面回归模型。并基于该模型,选择永磁驱动器齿槽转矩最小为目标,利用粒子群优化算法对其主要结构参数进行优化,得出最优结构参数组合。对斜极结构永磁驱动器分别进行了解析和优化,结果表明,优化方法可以显著地消弱永磁驱动器的齿槽转矩,避免产生转矩波动,提高了系统的控制准确度,证明所得出的结论是正确、有效的。

Abstract:In this paper, the magnet skewing structure is adopted to reduce the cogging torque in permanent magnet drive. The analytical method is used to give the expression of the cogging torque. The quadratic polynomials are employed to construct response surface model based on the response obtained by the Ansys software and the central composite design (CCD) experiment method. Based on this model, the minimal cogging torque is taken as the optimal objective, and then the particle swarm optimization (PSO) algorithm is used to perform optimization and obtain the optimal structure parameters of the PMD. At last, the permanent magnet drive with magnet skewing structure is analyzed and optimized with above method. The results verify that the cogging torque can be notably reduced with this optimization method.
