Abstract: The present invention provides a mover traveling along a track, the mover system having a mover frame supporting a mover sensor element and a track frame providing a path for which the mover frame travels and supporting track sensor elements for interacting with the mover sensor element of the mover frame. The interaction between the mover sensor element and track sensor elements provides an identification signal of each mover and the identification signal of each mover on the track is arranged according to a cyclic sequence where unique contiguous substrings occur only once within the sequence.

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 he 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: A distributed motor drive system includes a power management module and multiple inverter modules integrated with the motors and located on a machine or process remote from the power management module. The power management module distributes DC voltage and command signals to each of the inverters, where the DC voltage is distributed between modules via a DC link cable. The integrated inverters execute switching routines to convert the DC voltage to an AC voltage suitable for controlling the motor. Each of the power management module and the inverters includes a portion of the DC bus. The current on the DC link cable is monitored and general bus utilization as well as overload conditions are reported.
