Abstract
The switched reluctance motor (SRM), an environmentally friendly machine, is suitable for application in electric vehicles (EV) in recent days. This paper presents an SRM sensitivity analysis focussing on weight of the materials used for stator and rotor for use in electric vehicle application. Two SRM structures are considered, namely normal stator tooth and tapered stator tooth. Thirteen materials widely used in the SRM are considered for these two structures to perform the proposed sensitivity analysis. The major outputs of torque, speed, power, iron loss, efficiency, copper loss, and power factor are gathered through finite element analysis (FEA) simulation. Each of the 13 materials are examined for normal tooth and tapered tooth geometrical structures. The results are discussed, focusing on the fitness of the considered SRM structures for EV application. As weight-sensitive vehicles, the materials used in EVs are compared against the respective motor weights obtained through analysis to recommend the lightest motor for production.
