ABSTRACT:
An apparatus for feeding electric power to a movable body in a non-contact manner. Power lines on which electric power is transmitted are laid on a guide rail. The movable body is powered by the electric power from the power lines. A plurality of pick-up coils are positioned in the movable body for generating induced electromotive force as a drive voltage according to the electric power. The plurality of coils generate different voltages. A motor and a controller are connected to the coils. A motor is driven by a high voltage while the controller is driven by a low voltage.
