开关磁阻电动机（SRM）由于其高速度、多相重叠和机器参数的最佳控制操作、最大化每安培转矩和功率密度而在电力牵引电动机应用中变得更加普遍。作为直流系列电机和永磁体的替代品，近年来，SRM等专用电机的发展呈爆炸式增长。混合励磁开关磁阻电机（HESRM）是电动汽车（EV）应用的最新发展之一，它可以在变速时提供更大的转矩和功率密度。另一方面，HESRM拓扑结构开发了多种励磁技术，以将联合收割机稀土永磁体（PM）组件组合在一起，从而在有源区域中产生更大的通量。因此，当试图隐藏传统SRM的个性时，具有PM的HESEM技术导致不利的困难。为了提高HESRM的转矩性能，而不使用永磁体，本研究旨在开发和分析一种新的拓扑结构的SRM牵引电机。利用Ansys/2D麦克斯韦有限元法对新型混合储能材料的静动态特性进行了数值分析。实验验证了概念验证和软件分析方法。根据结果，与传统的SRM不同，新电机非常适合电动汽车，因为它具有高可靠性，可控性和冗余性，以及在广泛的速度范围内提供大量扭矩的能力。
Switched reluctance motors (SRMs) have become more prevalent in electric traction motor applications owing to their high speeds, multiple phase overlap, and optimal control operation of machine parameters, maximizing torque per ampere and power density. As an alternative to DC series motors and permanent magnets, the development of specialized electrical machines like SRMs has exploded in recent years. One of the most recent developments in electric vehicle (EV) applications is the use of hybrid excitation switching reluctance motors (HESRM), which can provide more torque and power density at variable speeds. HESRM topology, on the other hand, developed numerous excitation techniques to combine rare earth permanent magnets (PM) components to create greater flux in the active area. Thus, the HESEM technique with PM results in unfavorable difficulties when trying to hide the traditional SRMs’ individuality. In order to improve the torque performance of HESRM without using PMs, this research seeks to develop and analyze a novel topology for SRM traction motors. Furthermore, Ansys/2D Maxwell’s finite element approach is used for the new HESRM’s numerical analysis of static and dynamic behavior (FEM). The experiments verify the proof of concept and the software analysis method. According to the results, unlike traditional SRMs, the new motor is well-suited for EVs because of its high dependability, controllability, and redundancy, as well as its ability to provide a significant amount of torque at a wide range of speeds.
