MULTIPLEXED WIRELESS POWER TRANSMISSION SYSTEM FOR MOVING COMPONENT

摘要

A multiplexed wireless power transmission system for moving component is provided with at least two transmission and reception units 3 comprising a transmission antenna 5 for wirelessly transmitting power and a reception antenna 6 for receiving power from a corresponding transmission antenna 5. The transmission antennas 5 each comprise a spiral transmission-side coil 7 disposed so as to be centered on the axial center of a rotating body. The reception antennas 6 each comprise a spiral reception-side coil 8 disposed so as to be centered on the axial center of the rotating body and such that there is a space between the reception-side coil 8 and the transmission-side coil 7. Each transmission and reception unit 3 operates using an AC current having the opposite phase from an adjacent transmission and reception unit 3.
