本文提出了一种新型的双定子轴向磁通辐条式永磁游标电机，该电机具有高转矩密度和低速时高功率因数的特点，适用于直驱系统。介绍并讨论了该机器的工作原理和基本设计步骤。采用三维有限元法（3-D- fem）对其磁场和瞬态输出性能进行了分析。在此基础上，提出了机床基本设计和性能评价的解析方法和简化的二维有限元方法，有效地减少了三维有限元方法的建模和仿真时间，并获得了足够的精度。
This paper proposes a novel double-stator axial-flux spoke-type permanent magnet vernier machine, which has a high torque density feature as well as a high-power factor at low speed for direct-drive systems. The operation principle and basic design procedure of the proposed machine are presented and discussed. The 3-D finite element method (3-D-FEM) is utilized to analyze its magnetic field and transient output performance. Furthermore, the analytical method and a simplified 2-D-FEM are also developed for the machine basic design and performance evaluation, which can effectively reduce the modeling and simulation time of the 3-D-FEM and achieve an adequate accuracy.
