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.

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.

A linear motor system may include a plurality of track sections that may enable a mover to traverse a track formed by the plurality of track sections. The system may also include a plurality of connection modules, such that each connection module of the plurality of connection modules may physically couple two respective adjacent track sections of the plurality of track sections and communicatively couple the two respective adjacent track sections of the plurality of track section. Each connection module may also electrically couple the two respective adjacent track sections of the plurality of track section.
