EPS용 SRM의 고효율 저토크리플 구동방식

This paper presents a design and characteristics analysIs of a SRM drive for EPS(Electrically Power Steering) applicatIOn. A conventional dnving room space and mechanIcal structure are suggested in design stage In the restricted desIgn conditions, motor parameters are determined for sufficient torque and speed For the smooth torque generation and simple circuit of power system, 12/8 motor drive is considered. With FEM and magnetic circuit analysis, designed motor is simulated to meet the requirement of specifications. Effectiveness of the suggested SRM drive for EPS application is verified by the manufactured prototype motor drive tests.
