Analysis of a switched reluctance machine for EV application with torque smoothening strategy

摘要

The subject of the paper is focused on the analysis of a 30kW switched reluctance machine for propulsion of electrical vehicle propulsion (EV). The paper details the fundamental steps when developing such an electrical machine, and validates the structure using co-simulation procedures, coupling finite element analysis software (Cedrat Flux2D) with software used to implement the controller (Matlab/Simulink). As the advantages of the SRM are already known, the torque ripples are its main disadvantages. These are reduced as much as possible using a dedicated control strategy, the torque sharing functions (TSF). The solution offered by the paper highlights the possibility of using a cheap, reliable and robust electrical machine for propulsion unit.
