Electric Motor Drive Selection Issues for HEV Propulsion Systems: A Comparative Study

Abstract

This paper describes a comparative study allowing the selection of the most appropriate electric propulsion system for a parallel hybrid electric vehicle (HEV). This study is based on an exhaustive review of the state of the art and on an effective comparison of the performances of the four main electric propulsion systems that are the DC motor, the induction motor, the permanent magnet synchronous motor, and the switched reluctance motor. The main conclusion drawn by the proposed comparative study is that it is the cage induction motor that better fulfils the major requirements of the HEV electric propulsion.
