Several characteristics of switched reluctance drive (SRD) systems, such as high torque density, high efficiency, fault tolerant operation, and simplicity of construction make them potentially attractive for electric vehicle (EV) traction applications. This paper presents the results of an evaluation of the design and performance aspects of switched reluctance (SR) drive technology, with special emphasis on EV traction. Rotor/ stator design and construction, choice of materials, electronic component selection, and production costs are some of the important design and manufacturing issues analyzed. Performance characteristics such as drive control, torque ripple and noise, fault tolerance, efficiency, torque-speed characteristics, and regeneration are discussed. Several of these design and manufacturing issues are compared with similar issues for drive systems currently used for electric vehicle applications.
