Method and system for contactless power transfer in a linear drive system
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.

VEHICLE CONTROL SYSTEM AND METHOD
A control system includes an interface device having a body extending between a first end and a second end and that provides power to a vehicle system from an external power source. Sensors may be coupled with the interface device and detect sensor data associated with the coupling of the external power source with the interface device. A controller receives the sensor data from the sensors and determines a coupling location at which the external power source is coupled with the interface device. The coupling location may be at a first position between the first end and the second end of the interface device. The controller controls movement of the vehicle system to change the coupling location between the external power source and the interface device from the first position to a second position between the first and second ends of the body.

SYSTEMS AND METHODS FOR CONTROLLED TRAVERSAL OF PHASE BREAKS
A control system can include a controller that may obtain a location of a phase break along a route. The controller can monitor locations of a vehicle and determine when the vehicle will reach the phase break location. The system also may include a switch proximate to a collector device of the vehicle and/or an actuator that moves the collector device relative to a conductive pathway. The conductive pathway may operate to supply electrical power to the vehicle. The controller can actuate a switch, an actuator, or both the switch and the actuator, and (upon activation) can change a source of power for one or more loads for propulsion of the vehicle through the location of the phase break along the route.
