ELECTRIC VEHICLE (Construction and Working principle)
www.irjet.netIn most of the electric vehicle, Brushless DC motor is used which is better than brushed DC motor, permanent magnet DC motor. Brushless DC motor does not have brush and commutator, the electric vehicle which uses brushless DC motor has to use motor controller which helps to control various properties of motor to take sufficient current and
