A Review on Motor and Drive System for Electric Vehicle

Abstract

Due to the increasing adverse effect of global warming and the serious concern related to the depletion of fossil fuels our society is moving rapidly towards the use of electric vehicle. Nowadays, electric vehicles are preferred since they are environment friendly as they emit less greenhouse gases and less pollutant than conventional drives. The improvements in power electronic technologies have made it possible to achieve optimum performance of electrical vehicles for different load conditions. Freshly adopted techniques for driving the electric vehicles driven by induction motor which is utilized by the industries and the civilized society as well as associations that moves into viable expertise and recommended choice for the use of electric vehicles. In this paper investigation has been done over drive systems and different loss minimization techniques for EVs so that the controller can be designed for enhancing the efficiency of induction motor in every load condition by inclusion of core losses. This paper gives an evaluation and assessment over various loss minimization techniques used while driving the induction motor. It would help to operate the motor smoothly at optimum torque by elevating the efficiency/performance of the system during high load as well as in light load conditions. The various loss minimization methods generalize the system operation by reducing the copper loss and iron loss, reduced torque and speed control of the system. As the benefits of electric vehicle, countries can meet the environmental targets as well as provide the best alternative for the conventional drives by achieving the desired performance as required by the society and industries.KeywordsElectric vehicleMotor drive systemInduction motorLoss minimizationTorqueEfficiency
