Abstract: A method and system for motion control of movers in an independent cart system is disclosed. In one implementation, the independent cart system includes a plurality of track segments, each section having a respective controller. One of the controllers receives a motion command for a plurality of carts, respectively. The controller generates a force command for each of the plurality of carts and transmits the respective commands to the track segments commutating the plurality of carts.

Abstract: A curvilinear encoder is provided in which an incremental or absolute position for a cart can be detected on a track by applying one or more excitation signals and receiving one or more pick up signals. Analogous to a transformer arrangement, an encoder mover can be placed on the cart moving along the track, and an encoder stator can be placed on the track separated by a gap. The one or more excitation signals can be applied to the one or more excitation coils on the mover or the stator to generate one or more magnetic fields, and the one or more pick up signals can be received by one or more pick up coils on the mover or the stator for sensing changes in the magnetic fields produced by motion of the mover on the track.

Abstract: An independent cart system with safety functions that prevent unintended motion independently within different sections of the track while permitting motion along other sections of the track is disclosed. A safety controller receives one or more input signals corresponding to operating conditions along the track. A safety program executing in the safety controller monitors the state of the input signals to determine whether a safety function is to be executed. When a safety program is executed, the safety controller transmits an output signal to one or more segment controllers present in one section along the track. Each segment controller is responsible for regulating current flow to the coils mounted to the corresponding track segment. In response to the signal from the safety controller, each segment controller in the section controls the power output to the coils along that section of track to achieve the safe operation desired in that segment.

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.

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.
