    an electric motor is used to power the driven wheels. when the brake pedal is pressed, a commutator is actuated which changes the polarity of the motor and reverses its direction of rotation.

    due to inertia , the direction of rotation of the wheel dose not change instantly, but it helps to cancel the opposing torque of the motor, due to which the wheel comes to a dead stop.
