Electric Vehicle Candidature based on Electromagnetic Evaluation of the Double-Stator Wound-Field Flux Switching Machine

Abstract

The study is proposed to evaluate the design capabilities of two variants of the double stator wound-field flux modulating machines (DSWFFSMs) for electric vehicle drives. To achieve the aim of the study, the electromagnetic performance of a 24-slots/l0-pole double stator wound-field flux switching machine (DSWFFSM) is studied in finite element analysis (FEA) and compared with a 12-slots/l0-pole double stator DC-excited vernier reluctance machine (DSDCVRM). The static results show rated average torques of 47.7 Nm and 35.6 Nm, and the calculated efficiency are 91.3% and 88.9%, for the DSWFFSM and DSDCVRM, respectively. However, the DSDCVRM show superior performance under constant power speed range (CPSR) operation.
