A design & MATLAB simulation of motor drive used for electric vehicle

The electric vehicle is a key new transportation technology to reduce the pollution and to reduce use of fossil fuel. As the era of cheap fuel is coming to end, so the focus on the electric vehicle in India is increasing. In this paper the study of different forces acting on the vehicle are studied and the power requirement of the vehicle is evaluated. The survey of different motors presently used and there comparison is given. And according to the power requirement for electric vehicle size and other parameters of three phase induction motor is calculated. This motor is validated in MATLAB Simulink. Also a PWM inverter is design to supply the Motor and v/f speed control technique is used. To control the speed of deep-bar rotor induction motor a close loop system is used by comparing the speed of motor with set speed the frequency of supply is varied. Also a vehicle dynamics model is develop to validate the system.
