Mechanical coupling of two induction motor drives for the applications of an electric-drive vehicle system

This paper represent mathematical model for representing vehicle mechanics using Newton's Second law of motion. Automobile industries are investing much time and money to find out the practical alternative to vehicle powered by the internal combustion engine. Electric motors are best suited for vehicle application as they are capable of developing high starting torque. This has led to the development of battery-operated electric vehicle (EV), hybrid vehicles and fuel cell vehicles. Two prominent reason for this shift are pollution and fuel saving. Indian government has taken initiative to accelerate research and development in the field of electric vehicle by launching “National Electric Mobility Mission Plan 2020”. The focus in this paper is on the EV propulsion electrical motor drives. This paper gives an idea about the electric-drive vehicle (EDV) system on a test bench setup consisting of two induction motor drives coupled mechanically by one shaft for emulating on road operating conditions. MATLAB/Simulink results are presented on mechanical coupling of two drives on a common shaft to share the common load.
