EV Traction용 매입형 영구자석 동기전동기의 집중권 분포권에 따른 특성 비교

Abstract

This paper deals with the characteristic of interior permanent magnet synchronous motor(IPMSM) for traction of electric vehicle(EV). EV is an excellent alternatve for conventional inner combustion engine(ICE) vehicle. As high torque and wide operation range are essential for EV traction motor, IPMSM is suitable for EV traction application. Concentrated and distributed winding differ in characteristics of interior permanent magnet motor. Thus, this paper compares electric characteristics of concentrated and distributed winding. The finite element analysis(FEA) is performed both for concentrated winding model and distributed winding model to calculate characteristics such as torque, power, losses and efficiency.
