Optimize performance of Interior Permanent Magnet Synchronous Motor for electric vehicles transportation system

Abstract

Electric vehicle transportation system have gained increasing attention in recent years. Low weight, less volume and high efficiency are the main requirement of electric vehicles. Efficiency analysis of drive of electric vehicles is of major concern to increase its driving range per charge. This paper proposes Interior Permanent Magnet Synchronous Motor (IPMSM) Drive controlled by Field Oriented Control[1] with special focus on loss minimization for electric vehicle application. MATLAB simulation results are presented which takes into account the copper losses and iron losses. The results confirm the better response and efficiency improvement of IPMSM drive to increase the driving range. This paper also proves the overall increase in efficiency of the drive system despite of decrease of the inverter efficiency due to loss minimization control of IPMSM.
