Permanent Magnet Brushless DC Motor coupled with rear Axle in Hybrid Car.

Abstract

As the conventional energy resources are depleting there is an urgent need for switching to renewable energy resources as well as increasing its functionality. This paper proposes a design of coupling of brushless DC motor with a modified rear axle for a normal car. The Permanent magnet brushless DC motor is a high efficient in operation with high torque in range. The comparative investigation on the efficiency, weight, cost, cooling, maximum speed, and fault tolerance, safety, and reliability is carried out for switched reluctance motor, induction motor, permanent magnet blushless dc motor, and brushed dc motor drives, in order to find most appropriate electric motor drives for electric vehicle applications. The study shows permanent magnet brushless dc motor drives are the prior choice for electric vehicles. With ever-increasing concerns on our environment, there is a fast growing interest in electric vehicles (EVs) and hybrid EVs (HEVs) from automakers, governments, and customers.  As electric drives are the core of both EVs and HEVs, it is a pressing need for researchers to develop advanced electric-drive systems. In this paper, an overview of permanent-magnet (PM) brushless(BL) drives for EVs and HEVs is presented, with emphasis on machine topologies, drive operations, and control strategies.
