Abstract

Owing to the large quantity of conventional passenger vehicles with internal combustion engines, energy shortages and environmental pollution are now Seen as important problems. Electric vehicles (EVs) have the best energy savings and zero emission vehicles option. Radial Flux Switched Reluctance Motor (RFSRM), and Axial Flux Switched Reluctance Motor (AFSRM) have shown promise in wheel motor design of electric vehicles. While C-core is modelled, giving advantages of both radial and axial flux SRM. Based on a three-phase 12/16 pole structure, C-core RFSRM and conventional RFSRM are investigated and compared under different types of coils failures, while their impact on the average torque for both motors is presented. Comparisons of average torques at different coils` fault conditions between C-Core RFSRM, and conventional RFSRM have been done by finite element analysis (FEM). The segmental structure of C-Core RFSRM and its independent separate magnetic path for its coils, give it the superiority more than conventional RFSRM for in-wheel electric vehicle application.
