A comprehensive review of different electric motors for electric vehicles application

Vol. 15, No. 1, March 2024 | Sreeram Krishnamoorthy, Preetha Parakkat Kesava Panikkar
This paper provides a comprehensive review of various electric motors suitable for electric vehicle (EV) applications, focusing on their design aspects and performance. The motors discussed include DC motors, induction motors (IM), brushless DC motors (BLDC), permanent magnet synchronous motors (PMSM), and switched reluctance motors (SRM). The review highlights the advantages and disadvantages of each motor type, emphasizing the importance of factors such as cost, reliability, efficiency, torque, fault tolerance, excitation arrangements, and power density. The SRM is particularly highlighted due to its compact size, wide speed range, low cost, high efficiency, and fault tolerance. However, its application in EVs is currently limited by torque ripples and acoustic noise. The paper analyzes the performance of an SRM-based EV using MATLAB Simulink, focusing on parameters like speed, torque, flux, and state of charge (SOC). The results indicate that while the SRM drive shows good performance, the radial noise and torque ripple need to be reduced without compromising torque density and performance. The paper concludes by emphasizing the potential of SRMs in EV applications, especially if the issues of torque ripples and noise are addressed through advanced control techniques. The obtained model can serve as a foundation for further research and development in improving the performance of SRM drives for EVs.This paper provides a comprehensive review of various electric motors suitable for electric vehicle (EV) applications, focusing on their design aspects and performance.
