Design of Novel Double-Stator Switched Reluctance Motor Drive System for Electric Vehicles

This article proposes a novel drive system, which is applied to a novel double-stator switched reluctance motor (DSSRM). This motor has five work modes due to its structural characteristics, but the drive system composed of a traditional power converter cannot fully realize the five work modes. The drive system composed of the novel power converter can realize five work modes of the motor. First, the operating states of the novel power converter drive system in the five work modes are analyzed in this article, and the steady-state and transient simulation analyses are carried out. In addition, this article also analyzes the fault of the novel drive system and designs remedies to improve its reliability. Finally, a prototype of the 16/18/16 structure is fabricated and the drive system is built. The practical feasibility of the drive system is verified through experiments, which lays a theoretical foundation for the popularization and application of DSSRM in the field of electric vehicle drive system.
