Design of a Switched Reluctance Motor for a 48 V Hybrid Electric Vehicle Propulsion Application

Abstract

Switched Reluctance Motors (SRMs) are a promising motor type to reduce the cost of electrified vehicle propulsion systems in the near future. This study presents the design and analysis of a 12/8 SRM for a 48 V, 30 kW Full Hybrid Electric Ve-hicle (FHEV) propulsion application. The proposed design aims to meet the performance requirements of the target Permanent Magnet Synchronous Motor (PMSM) with an SRM that does not require rare-earth permanent magnets. This work addresses the design challenges of the SRM of this application, especially in high-speed operating region. The performance of the SRM drive has been optimized for the entire torque-speed curve using a weighted single objective genetic algorithm based optimization in MATLAB/Simulink. The efficacy of the SRM design is validated through simulation studies for various operating points of the targeted application.
