Title:
無線電力伝送による可動部多重化伝送システム
Document Type and Number:
Japanese Patent JP5449502
Kind Code:
B1
Abstract:
A system has primary transmission power supply 1 that supplies power; transmitter-receiver 3 including plural channels of transmitting antennas 5 that wirelessly transmit supplied power and plural channels of receiving antennas 6 that receive power from paired transmitting antennas 5; plural channels of transmission power circuits 2 that establish resonance conditions of paired transmitting antennas 5; and plural channels of receiving power circuits 4 that establish resonance conditions of paired receiving antennas 6. Transmitting antennas 5 have transmitting-side coils 8 approximately centered around the axis of a rotating body or arranged around the axis; and transmitting-side spacers 7 with prescribed permeabilities arranged to control magnetic flux caused by transmitting-side coils 8 for individual channels. Receiving antennas 6 have receiving-side coils 10 placed in the same manner as transmitting-side coils 8; and receiving-side spacers 9 with prescribed permeabilities arranged to control magnetic flux caused by receiving-side coils 10 for individual channels.
