Comparative study of 2D designs of 12/8 and 10/8 switched reluctance motors using ANSYS Maxwell

Abstract

The switched reluctance motor (SRM) is one of the common industrial applications where many fields of different models are used, but they differ in performance, thus the selection of the appropriate prototype must be determined according to the application's requirements. In this study, a comparative analysis was conducted between 12/8 and 10/8 switched reluctance motors (SRMs) using ANSYS Maxwell where the same dimensions, parameters, and operating conditions were adopted in the designs and only the number of stator poles were changed to evaluate the magnetic, mechanical, and electrical characteristics. Then we study their effect on the SRMs performance focusing on several aspects of torque, speed, various losses, electromagnetic analysis of intensity, and magnetic flux density. Electrical losses were reviewed, and the study revealed significant differences between the SRMs' electromagnetic performance, highlighting the importance of the SRM design to reduce losses and improve efficiency. The results show that the importance of choosing between the two SRMs depends on the application requirements, whether it requires high speed and efficiency or high torque. This study provides a comprehensive insight into the SRM designs deep analysis, supporting the drive for more efficient and sustainable technology in optimizing the electric motors' overall performance.
