In this article, a 16/6 bearingless switched reluctance motor (BSRM) with segment hybrid rotor teeth has been presented. To realize the decoupling control of torque and suspension force, the rotor teeth were divided into three torque teeth and three suspension teeth, and both of them are embedded in support part. First, both torque and suspension force are generated by short‐circuit excitation, the flux linkage coupling between torque windings and suspension windings was eliminated, and the separate control of torque and suspension force was achieved. Then, by increasing the pole arc of suspension teeth, the inductance of suspension windings is kept constant, which eliminates the influence on the output torque when adjusting suspension force. Finally, the coupling degree is further reduced by using nonmagnetic material as the supporting part. In addition, to achieve a greater output torque, the torque teeth are processed into U‐shape and optimized the pole arc of stator teeth and rotor teeth. The characteristics of inductance, flux linkage, and output torque are analyzed by the finite‐element method, and the results show that the proposed structure basically achieves the decoupling control of torque and suspension force. © 2020 Institute of Electrical Engineers of Japan.

分段混合转子齿的16/6无轴承开关磁阻电机的设计与分析

在本文中，提出了具有分段混合转子齿的16/6无轴承开关磁阻电机（BSRM）。为了实现扭矩和悬架力的解耦控制，将转子齿分为三个扭矩齿和三个悬架齿，它们都嵌入支撑部件中。首先，通过短路励磁产生扭矩和悬架力，消除了扭矩绕组和悬架绕组之间的磁链耦合，并实现了扭矩和悬架力的单独控制。然后，通过增加悬架齿的极弧，使悬架绕组的电感保持恒定，从而消除了在调节悬架力时对输出转矩的影响。最后，通过使用非磁性材料作为支撑部件，进一步降低了耦合度。此外，为了获得更大的输出扭矩，扭矩齿被加工成U形并优化了定子齿和转子齿的极弧。用有限元方法分析了电感，磁链和输出转矩的特性，结果表明，该结构基本实现了转矩和悬架力的解耦控制。©2020日本电气工程师学会。由John Wiley＆Sons，Inc.发布 ©2020日本电气工程师学会。由John Wiley＆Sons，Inc.发布 ©2020日本电气工程师学会。由John Wiley＆Sons，Inc.发布
