ABSTRACT:
A non-contact feeder system to supply an induced current to an electrical load includes at least three feeding cables arranged approximately parallel with one another along a moving direction of the electrical load; a plurality of AC power supplies to supply AC currents to the feeding cables; pick-up parts to supply an induced current, induced from a magnetic field formed by the AC current flowing through each of the feeding cables, to the electrical load and to be movable along the feeding cables without contacting the feeding cables as the electrical load moves; and a controller to control the plurality of AC power supplies, so that phases of the AC currents supplied from the AC power supplies are the same, and directions of the AC currents flowing through the feeding cables positioned adjacent to one another are reverse with respect to one another. Thus, the space to mount components in the non-contact feeder system is decreased and the induced current is improved.
