Kind Code:
A1
Abstract:
The present invention has: a tower; a nacelle that is provided in the upper portion of the tower and that rotates about a rotation axis which is in a direction along the axial direction of the tower; a power generator which generates power by using the rotational force of a windmill rotatably supported by the nacelle; and a power transmission unit including a first substrate fixed to the nacelle, a first coil which is provided to the first substrate and to which power is supplied from the power generator, a second substrate fixed to the tower, and a second coil which is provided to the second substrate and which faces the first coil across the first substrate and the second substrate. In the power transmission unit, the power supplied to the first coil is transmitted to the second coil by a magnetic field resonance of the first coil with the second coil.
