Abstract
This paper introduces a novel double stator switched reluctance machine (DSSRM). U-shaped stator blocks are used for both internal and external stators. Each stator tooth is wound with a central winding, and the polarities of the two stator teeth on each U stator block are opposite. Firstly, the working principle and the geometric design of the proposed DSSRM are given. The methods of reducing torque ripple from machine structure of the proposed DSSRM are illustrated. Then, this paper makes the comprehensive comparison between conventional DSSRM and proposed DSSRM by finite element method (FEM). The simulation results indicate that this proposed DSSRM has lower torque ripple and higher torque density than the conventional DSSRM. Finally, a prototype motor is manufactured and the simulation analysis is validated by the experimental results.
