The increasing trend of population and its one of the requirements, on road vehicles are increasing. In addition, rural to urban development and subsequent deforestation leads to ozone depletion, climate change, loss of biodiversity and finally global warming encourages to research to give the substitute for IC Enginevehicles by developing electric vehicles. Present 20–35% of world economy is driven by IC Engine vehicles and now upcoming challenge is to develop equivalent and better technical solutions to sustenance environment with green vehicles. The existing developed electric vehicles has limitation to work under controlled environment and suitable for good road conditions. However, the requirement is to develop the continual torque operative motor which can be suitable for Indian road, Indian weather conditions and which can overcome the IC Engines. This is preliminary design investigation of motor for operative torque performance considering the different design parameters for stator slot configurations, slots/pole ratios, rotor configurations, combination of different types of magnetic materials, stack length, back iron, and dimensions of the effective magnet. The design simulation is done in RMxprt as per the important required characteristics of the electric vehicles (EVs).
