This article presents a new type of axial-field switched reluctance machine (AFSRM) and axial-field dual-rotor segmented switched reluctance machine (ADS-SRM), along with its design methodology. The proposed ADS-SRM is featured by the segmental stator and rotor poles, the auxiliary flux-conductive rings, and the concentrated windings. The yokeless topology reduces the active length of the motor. Besides, the adopted short-end winding layout increases the slot-fill factor and the motor’s reliability. First, the basic topology of ADS-SRM is introduced along with its operating principle and various stator/rotor pole combinations. The three-phase 12/8 configuration of ADS-SRM is chosen for further analysis. Then, the design methodology considering the fringing and leakage field effects through the magnetic equivalent circuit (MEC) method is developed, and the flowchart detailing the design procedure is presented. Through the comparison with the conventional yokeless and segmented armature (YASA) topology, ADS-SRM exhibits excellent performance at overload conditions. The prototype is designed and fabricated, and the experimental results verify the motor performance.

新型轴场双转子分段开关磁阻电机的研制与研究

本文介绍了一种新型的轴场开关磁阻电机（AFSRM）和轴场双转子分段开关磁阻电机（ADS-SRM），以及其设计方法。拟议的ADS-SRM具有分段定子和转子极，辅助磁通环和集中绕组的特点。无轭拓扑减少了电动机的有效长度。此外，采用的短端绕组布局增加了插槽填充系数和电机的可靠性。首先，介绍了ADS-SRM的基本拓扑及其工作原理以及各种定子/转子磁极组合。选择ADS-SRM的三相12/8配置进行进一步分析。然后，开发了通过磁等效电路（MEC）方法考虑边缘和泄漏场效应的设计方法，给出了详细设计过程的流程图。通过与传统的无轭和分段电枢（YASA）拓扑进行比较，ADS-SRM在过载条件下表现出出色的性能。设计并制造了原型，实验结果验证了电动机的性能。
