MOVABLE PORTION TRANSMISSION SYSTEM USING WIRELESS POWER TRANSMISSION
First Claim
1. A movable portion transmission system using wireless power transmission which is performed via a rotary member, said movable portion transmission system comprising:
- a primary transmission power supply to supply electric power;
a transmitter and receiver configured with a transmission antenna to perform wireless transmission of the electric power from said primary transmission power supply, and a reception antenna to receive the electric power from said transmission antenna with which said reception antenna pairs up;
a transmission power supply circuit to establish a resonance condition of said transmission antenna with which said transmission power supply circuit pairs up; and
a reception power supply circuit to establish a resonance condition of said reception antenna with which said reception power supply circuit pairs up,wherein said transmission antenna comprises a transmission side coil in a spiral shape which is arranged while being centered at an axial center of said rotary member, and said reception antenna comprises a reception side coil in a spiral shape which is arranged with a gap therefrom to said transmission side coil while being centered at the axial center of said rotary member.
