Review of Traction Motors for Electric Vehicle Application

The accelerating demand for electric vehicles (EVs) and the necessity to reduce fossil fuel dependence have intensified research on advanced traction motor technologies. This paper presents a comparative analysis of key traction motors including DC Series, Induction, Permanent Magnet Synchronous (PMSM), Switch Reluctance (SRM), and Brushless DC (BLDC) motors. A quantitative evaluation is conducted considering torque density, efficiency, and cost-effectiveness. Results indicate that PMSMs achieve peak efficiencies of 93-95% with excellent speed control, while induction motors maintain strong cost-performance ratios. SRMs offer durability and fault tolerance but exhibit torque ripple, whereas BLDCs provide compact integration with high dynamic response. These insights serve as guidelines for EV motor selection.
