基于RMxprt磁路法的双定子永磁无刷直流电机设计方法

摘要

双定子永磁无刷直流电机(DS-PMBL)因其高机械集成度、高转矩密度而具有较高的应用价值.但其特殊的结构,难以用现有的设计程序进行电磁设计.将基于Ansys软件中的RMxprt模块并结合传统磁路计算法,借助定子裂比优化法探讨将DS-PMBL拆分成两个单定子永磁无刷直流电机(内电机和外电机),分别展开设计,最终将两个设计方案合理拼接成DS-PMBL模型,并通过相关仿真试验验证模型的性能.%Dual-Stator Permanent Magnet Brushless (DS-PMBL) has great application value by itshigh mechanical integration and high torque density.However,DS-PMBL can not be designed by current program because of its special structure.Probed into splicing the whole DS-PMBL design as two parts design-inside motor&outside motor based on the RMxprt with traditional magnetic circuit method by split ratio of stator.Finally,the model's performance would be verified by curve of magnetostatic air-gap flux density and dynamic simulation.
