FEEDER DEVICE FOR ELEVATOR

摘要

PROBLEM TO BE SOLVED: To supply electric power to the cage of an elevator without using a feeder cable. SOLUTION: A feeder device for an elevator is provided with a conductor which is installed in parallel with the moving route 3 of a cage 1 and through which a high-frequency current flows, a coil 5 which is fitted to the cage 1 and moves together with the cage 1 along the conductor 4, and a power receiving circuit 6 fitted to the cage 1 and connected to the coil 5 to supply an electromotive force generated in the coil 5 by the magnetic field formed by the conductor 4 to the power receiving circuit 6 fitted to the cage 1.
