Summary:The switched reluctance motor (SRM) has gained significant attention in the industry due to its advantageous features, such as a durable rotor, simple stator windings, and ease of manufacturing. The main focus of SRM development has been enhancing efficiency while reducing torque ripple and losses. Given that this study aims to apply the proposed SRM design in electric vehicles, it is crucial to achieve a motor that is free from torque ripple and exhibits high efficiency. This research proposes a novel type of SRM called the outer rotor permanent magnet SRM (ORPMSRM) specifically for lightweight electric vehicles. Structural modifications are introduced in the ORPMSRM design to improve the torque characteristics and minimize losses. The electromagnetic analysis is conducted to predict the performance of the ORPMSRM with these modified structures. This article offers a comprehensive investigation that considers various configurations of rotor poles and stator poles with permanent magnets (PMs) to enhance the performance of the ORPMSRM. The finite element analysis (FEA) results are compared with experimental results, providing valuable insights into the motor's performance and validating the analytical predictions.
