Abstract
An independent cart system provides a track assembly having a first, second, and third portion with the first and second portions providing drive coils mounted along the length of the track and flanking the second portion devoid of drive coils, the second portion providing an energy transfer coil. A plurality of movers operative to travel along the track, and have a drive member and a pick-up coil mounted for electrical interaction with the energy transfer coil when a given mover is aligned with a given second track portion. The first and second track portions include current drive circuits providing current to respective drive coils to generate electromagnetic fields which engages mover drive members to propel each movers along the track and the second track portion includes an energy transfer circuit providing current to the energy transfer coil to transfer electrical energy through mutual inductance to pick-up coils of the movers.
