Optimizing SRM Design for Electric Vehicles: A Solution to Torque Ripple

This paper explores the design and analysis of a 1 H.P. 6/4 Switched Reluctance Motor (SRM) configuration for Electric Vehicles (EVs). The main objective is to optimize electromagnetic characteristics, such as torque output, ripples, and efficiency, while considering size and other constraints. The study also aims to improve switching strategies to minimize torque ripple and losses across different operating conditions. The ultimate goal is to contribute to the design and development of robust and reliable SRM and drive systems. Although SRMs offer benefits such as fault tolerance and variable speed capabilities, they often suffer from torque fluctuations. The study uses Ansys Maxwell 2D software to analyze the motor design, focusing on parameters like output power, stack length, and outer stator diameter. Additionally, the paper proposes an approach to reduce torque ripple by adjusting turn-on and turn-off angles, which can significantly improve the efficiency of the SRM drive, making it more suitable for EV applications.
