A Future Review and Reliability Evaluation of PMSM in EV

Abstract

In recent years, electric motors have advanced to meet the demands for improved efficiency, reliability, and sustainability. These motors enhance the driving experience by boosting torque, acceleration, and overall performance. As vehicle power output rises, there is increasing focus on cost, efficiency, and driving dynamics. This paper examines the reliability of motors used in EVs and their drives. It thoroughly reviews relevant research, incorporating findings from various studies on dynamic reliability, fault tolerance, and thermal effects. The engineering strategies and comparative insights provided here offer a practical guide for future research and development in EV motor drive reliability. This article delivers a comprehensive review of the comparative reliability of PMSMs compared to other EV motor drives, highlighting their performance in dynamic conditions, design challenges, and fault-tolerant features.
