本文旨在将分区定子(PS)开关磁通永磁(SFPM)电机的拓扑结构应用于直接驱动风力发电机。采用了一种新型的定子内侧凸起的分段定子电机。将所设计的电机与一台内定子为圆柱形、外转子为一台的永磁同步电机进行了性能比较。简要介绍了PS和OR SFPM电机的分析设计。应用二维有限元模型研究和比较了三种具有相同尺寸的全局优化电机设计的电磁性能。基于有限元结果，PS机床比OR SFPM机床表现出更高的效率和更高的扭矩密度。此外，新型凸起内定子PS电机具有与圆柱形内定子PS电机相同的电磁性能，定子内铁心材料减少了37.5%。
This paper aims to apply the Partitioned Stator (PS) Switched Flux Permanent Magnet (SFPM) machines topology to direct drive wind generator applications. A novel partitioned stator machine with salient inner stator is applied. The performance of the applied design is compared with a PS SFPM machine with cylindrical inner stator and an Outer Rotor (OR) SFPM machine. The analytical design of the PS and the OR SFPM machines is briefly presented. 2D finite element models were applied to study and compare the electromagnetic performance of three globally optimized machine designs having the same size. Based on finite element results, the PS machines exhibit higher efficiency and higher torque density compared to the OR SFPM machine. In addition, the novel salient inner stator PS machine provides the same electromagnetic performance of the cylindrical inner stator PS machine with 37.5% reduction of the inner stator core material.
