NON-CONTACT CURRENT FEED SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a non-contact current feed system capable of decreasing the installation space and enhancing the efficiency of the induction current induced. SOLUTION: The non-contact current feed system to supply induction current to a load is equipped with at least three current feed cables laid approximately parallel with each other along the moving direction of the load, a plurality of AC current supplying sources to supply AC current to the cables, a pickup part to supply to the load an induction current induced from a magnetic field formed by AC current flowing in each cable and arranged movable in the non-contact condition with the cables along the cables when the load makes movement, and a control part to control the AC supplying sources so that the phases of the AC currents fed from the supplying sources are identical and the directions of the AC currents flowing in the cables adjoining mutually are opposite to each other.
