Abstract
A system and method for wirelessly providing power to independent movers traveling along a track includes a sliding transformer to transfer power between the track and each mover. The sliding transformer includes a primary winding extending along the track and a secondary winding mounted to each mover. Each of the primary and secondary windings may be formed of a single coil or multiple coils. The primary and secondary windings are generally aligned with each other and extend along the track and along the mover in the direction of travel with an air gap present between the windings. A power converter on the mover may regulate the power supplied 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.
