Abstract
A system and method for providing power to independent movers traveling along a track in a motion control system without requiring a fixed connection between the mover and a power source external to the mover. In one embodiment, a sliding transformer transfers power between the track and each mover. In another embodiment, an optical transmitter transfers power between the track and an optical receiver mounted on each mover. In yet another embodiment, a generator includes a drive wheel engaging the track as each mover travels along the track. A power converter on the mover receives the power generated on and/or transmitted to the mover to control an actuator or a sensor mounted on the mover or to activate drive coils mounted on the mover to interact with magnets mounted along the track and, thereby, control motion of each mover.
