The Application and Study of Brushless DC Motor in EV

With the development of economy, vehicle fuel consumption and the needs of environment protection, greater importance is attached to the spreading and development of electric vehicle. This paper briefly introduces the development of motor in the electrical driving system of electric vehicle and tells us how to produce constant maximum torque by establishing a mathematic model. At last, it points out the development and problems existing in electrical driving system of electric vehicle which still need to be solved in future research.
