摘要

The rapid advancement of electric vehicle (EV) technology highlights the need for a thorough understanding of the performance and reliability of various motors used in EVs. A key challenge is ensuring accurate and consistent data collection under identical operating conditions for a fair comparison. This study aims to conduct a comprehensive comparative analysis of Permanent Magnet Synchronous Motors (PMSM) and Switched Reluctance Motors (SRM) for EV applications. Suitable PMSM and SRM models were selected based on a detailed literature review and manufacturers’ specifications. The experimental setup measures key parameters, including torque-speed characteristics, efficiency, power consumption, and thermal performance. Performance evaluation includes analyzing the efficiency of both motor types across varying operational speeds and loads to understand their characteristics. Energy consumption data is collected under different driving conditions such as acceleration, deceleration, cruising, and idling, with data accuracy enhanced through a fuzzy decision algorithm. A Failure Mode and Effect Analysis (FMEA) is performed to identify potential failure modes, assess impacts on operations, and prioritize risks, thus improving motor reliability and performance. The results show that PMSM consistently outperforms SRM in efficiency, achieving 94.2% at 2000 RPM compared to 90.5% for SRM. This comparison is analyzed using Python software. Future research may explore advanced control algorithms to optimize PMSM performance in EV applications.
