Switched Reluctance Machine For A Starter-Alternator Micro- Hybrid Car

Living in a world where environment protection and energy conservation are the first worries, the development of hybrid vehicle seems to be an accelerated pace. There for, recent efforts are directed toward developing an improved propulsion system. One of the most valuable solutions is the starter alternators [19]. This paper presents an advanced development of a switched reluctance starter-alternator for a micro-hybrid vehicle. The performance, efficiency and torque characteristics of switched reluctance machines combined with its robust, low cost construction makes that technology an interesting alternative to other machine types chosen for traction applications especially starter/generator. This paper will provide an overview of the present status of hybrid vehicles worldwide and their state of the art, with emphasis on the engineering philosophy and key technologies. Using the Finite element method by the program FEMM we also present a model of switched reluctance machine 12/8 proposed for starter-alternator application.
