Abstract

In this paper, a new 6/10 hybrid switched reluctance motor (HSRM) is proposed. This original topology deploys permanent magnets (PMs) between adjacent stator poles of a divided teeth SRM. The function of the PMs is to weaken the magnetic saturation in stator poles, which is a major obstacle of torque improvement for divided teeth SRMs. Besides, the magnetic flux in the airgap increases as well. Hence, the output torque can be increased significantly. The flux distribution of the topology is analyzed by using an equivalent magnetic circuit. The topology is optimized by using the genetic algorithm for the best torque performance. Additionally, the characteristics of the proposed topology are compared with a 12/10 SRM, a 6/10 two-teeth SRM, a 12-slot, 10-pole three-phase six-state PM brushless DC motor, and a flux switching permanent magnet motor of the same dimension. A prototype of the proposed topology is built for experimental verification. The simulation and experimental results indicate that the proposed topology can achieve high torque density and high PM utilization factor simultaneously.
