Synchronous Reluctance Rotor Design Considerations based on Winding Configuration

This paper systematically investigates the feasibility and effectiveness of various winding configurations for synchronous reluctance motor (SyRM). The influence of winding configuration on effective saliency is analyzed and verified using finite element analysis. A select few slots per pole per phase combinations of SyRM are designed and preliminary comparison of their performance presented at rated operation. Rotor geometry optimization is utilized to identify desirable geometric design characteristics based on the winding configuration. The dependency of the SyRM rotor geometry on space harmonics generated by the winding function allows for a winding configuration dependent design strategy of SyRM rotor based on the analysis presented in this work.
