双定子永磁无刷直流电机(DSPMBL)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DSPMBL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DSPMBL模型,并通过相关仿真试验验证模型的性能。

DualStator Permanent Magnet Brushless (DSPMBL) has great application value by itshigh mechanical integration and high torque density. However, DSPMBL can not be designed by current program because of its special structure. Probed into splicing the whole DSPMBL 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 airgap flux density and dynamic simulation.
