Dynamic Behavior Analysis of PM Assisted SynRM for Electric Vehicular Application

Electric vehicles (EVs) require high-performance motors that offer a balance between efficiency, torque, and cost. PM-assisted Synchronous Reluctance Motors are one of the highly opted options in this area due to their potential for achieving this balance. This study investigates the dynamic behavior of PMA-SynRMs for EV applications. The analysis mainly focuses on understanding the motor’s performance under various dynamic operating conditions, such as varying speeds and loads (current). In this paper, Finite Element Analysis (FEA) is considered to achieve accurate results, by developing dynamic model of the PM-assisted SynRM, thereby, incorporating the interaction between PM, rotor structure with flux barriers and electrical windings. The investigated dynamic performance parameters include torque-speed characteristics, torque ripple, air gap flux density, back emf, power factor, cogging torque, efficiency etc. Overall, this investigation contributes to the development of high-performance electric motors for electric vehicles, paving the way for a more sustainable and efficient transportation future.
