Title:
CONTACTLESS POWER TRANSMISSION APPARATUS AND ROTATING ELECTRIC MACHINE
Document Type and Number:
WIPO Patent Application WO/2016/009814
Kind Code:
A1
Abstract:
This contactless power transmission apparatus is provided with a rotary electrode and a stationary electrode. The rotary electrode is fixed to a rotatable rotary body and is shaped like a flat ring protruding in the radial direction from an outer circumferential surface of the rotary body. The stationary electrode has an insertion through-hole through which the rotary body is inserted and is shaped like a flat ring that is retained so as not to rotate along with the rotation of the rotary body. The rotary electrode and the stationary electrode are disposed opposite each other in the axial direction of the rotary body to form a coupling capacitor. Power is transmitted via the coupling capacitor in a contactless manner.
