This technology removes or cancels all or nearly all of the back electro-motive force (emf) or counter emf in a DC motor. With its back emf significantly reduced, a DC motor can be operated at a significantly reduced voltage. This dramatically increases the distance a vehicle powered by such a motor can travel. The weight of the motor is increased, and a special motor control circuit controls the speed and torque of the motor.
