Abstract

See full text

A system for wirelessly transmitting power between a track and independent movers in a motion control system includes a pick-up coil provided proximate to the magnets on the movers. The fundamental component of the voltage applied to the drive coils interacts primarily with the magnetic field generated by the permanent magnets on the movers and not with the pick-up coil. Consequently, the pick-up coil does not interfere with desired operation of the movers but rather, interacts primarily with the harmonic components and has current and voltages induced within the pick-up coil as a result of the harmonic components. The energy captured by the pick-up coil reduces the amplitude of eddy currents on the mover. After harvesting the harmonic content, the pick-up coil may be connected to another circuit on the mover and serve as a supply voltage for the other circuit.
