Electric vehicles with higher energy efficiency, low

maintenance cost and pollution free operation, are offering great alternative to popular conventional IC engine vehicles. Also, with the advancement in technology, electric vehicle manufacturers are able to overcome the traditional drawbacks of electric vehicles, making it more and more suitable for modern day transportation. A motor in an electric vehicle provides the necessary force for the propulsion of a vehicle, which makes it the heart of electric vehicles. Different types of electric motors are compared on the basis of certain parameters which should be considered for selecting a particular motor type for electric vehicle application.

Therefore hybrid and electric vehicles are going to be popular due to sustainability, energy saving and zero emission. Electric motors play significant role in In-wheel motor technology is being used in modern   electric vehicles to improve efficiency, safety and controllability of vehicle nowadays. BLDC motor have been demanding as in-wheel motor in electric vehicles because of high efficiency, desired torque versus speed characteristics, high power density and low maintenance cost. In this paper BLDC motor with ideal back-EMF is modeled and simulated in MATLAB/SIMULINK. Simulation model of the controller and BLDC drive are presented. In order to validate the model various simulation models are studied. Simulations results depict from developed model are satisfactory and show performance of model.
