开关磁阻电机（SRM）由于其多功能性、结构简单、维护成本低、转矩和功率能力高而得到世界范围的认可。最近的发展是在SRM的指数增长作为直流和永磁电机的替代品。开关磁阻电动机的混合励磁提高了变速应用的转矩能力。与稀土金属集成的HESRM方法采用永磁体（PM）行为并增强气隙磁通密度。然而，使用永磁体的HESRM方法抑制了SRM的独特性能。在本文中，一种新的拓扑结构，以提高平均转矩的HESRM不使用永磁体。此外，静态和动态特性的机器检查的二维有限元法（FEM）。结果表明，该电机具有良好的响应特性，平均转矩最大，转矩涟漪最小，可有效地应用于电动汽车。
Switched reluctance motors (SRMs) have worldwide recognition due to their versatility, simple structure, and low maintenance cost with high torque and power capability. Recent developments are being made in SRMs which exponents its growth as a substitute for DC and permanent magnet motors. Hybrid excitation of switched reluctance motor (HESRM) improves the torque capability for variable speed applications. The HESRM methods integrated with rare earth metals adopt the permanent magnet (PM) behavior and intensify the airgap flux density. However, the HESRM method with permanent magnets suppresses the unique properties of SRM. In this paper, a new topology is introduced to enhance the average torque of HESRM without using PMs. Furthermore, the static and dynamic characteristics of the machine are examined by the 2D finite element method (FEM). The results indicate that excellent motor response is obtained with maximum average torque and minimum torque ripple and can be effectively used in electric vehicles.
