Description
Due to the increase in the cost of fuels and pollution, alternative to conventional internal combustion engine powered vehicles is needed. Electric vehicles are by many seen as the cars of the future as they are very efficient, produce no local pollution, are silent, and can be used for power regulation by the grid operator. In an electric vehicle various components like motor, battery, controllers are used. While designing an electric vehicle, the first and foremost component to be selected is an electric motor which replaces the Internal Combustion engines of conventional vehicles. Therefore, electric motor used in an electric vehicle must produce appropriate power and other characteristics that are required for traction purpose. The design or rating of each component is a difficult task as the parameters of one component affect the power level of another one. There is therefore a risk that one component is rated inappropriately which may make the vehicle unnecessary expensive or inefficient. This paper presents a model of electric vehicle that is driven by a Permanent Magnet Synchronous Motor. The motor is directly coupled with the axle, thus increasing the efficiency of the vehicle. The speed control of the motor can be directly achieved by the Field Oriented Control (FOC) Method and Space Vector Pulse Width Modulation (SVPWM). The model has been simulated in PSIM 2022 software.
