随着对节能自动化的需求日益增长，大多数应用都在寻求创新的解决方案，这些解决方案可以在广泛的速度范围内提供高等级的性能，并可以在恶劣的操作条件下运行。用于车辆、航空航天和军事应用的推进和发电系统是对电机有这种需求的一些典型领域。开关磁阻电机（SRM）符合这些要求，但往往被视为一个嘈杂的替代需要提高效率。SRM的常规应用考虑定子极的数量高于转子极的数量的几何形状。本文提出了一套新的拓扑结构的SRM，这还没有被探索。具有Nr个转子极和Ns个定子极的定子-转子配置的设计由表示为Nr = 2Ns − 2的新的极设计（PD）关系给出。这样的定子和转子极组合提供了具有最小转矩涟漪和更好效率的SRM设计，具有可比的热额定转矩和功率密度，同时对于与许多应用相称的大批量生产来说也固有地更便宜。该概念已被分析，模拟和实验验证。参数，如热性能，转矩涟漪，效率和功率密度进行了评估。
With an increasing need for energy-efficient automation, majority of applications have sought after innovative solutions that can deliver high-grade performance over a wide range of speeds and can operate under harsh operating conditions. Propulsion and generation systems for vehicular, aerospace, and military applications are some of the typical areas that resent such demands for electric machines. Switched Reluctance Machines (SRM) fit these requirements, but have often been viewed a noisy alternative with a need to increase efficiency. Conventional applications for the SRM consider geometries in which the number of stator poles is higher than the number of rotor poles. This paper presents a novel set of topologies for the SRM, which have not been explored. Design of the stator-rotor configuration with Nr rotor poles and Ns stator poles is given by a novel Pole Design (PD) relationship expressed as Nr = 2Ns − 2. Such stator and rotor pole combinations provide SRM designs with minimal torque ripple and better efficiency with comparable thermally rated torque and power densities while also being inherently less expensive for high volume production commensurate with many applications. The concept has been analyzed, simulated, and experimentally verified. Parameters such as thermal performance, torque ripple, efficiency, and power density have been evaluated.
