Title:
NON-CONTACT POWER GENERATOR
Document Type and Number:
WIPO Patent Application WO/2016/199848
Kind Code:
A1
Abstract:
[Problem] To provide a non-contact power generator that has a good magnetic efficiency and little leak of magnetic flux. [Solution] A non-contact power generator 1 is provided with: a magnet 3 that is disposed opposite to and apart from one main surface of a moving body that moves both in one direction and in the direction opposite said one direction, wherein the magnet can move along the axis extending in the movement direction of the moving body, and generates a magnetic flux that passes through the one main surface; a coil 4 that is disposed apart from a surface on the side opposite a surface facing one main surface of the magnet, and is interlinked with the magnetic flux from the magnet; and a magnetic flux guide member 5 that is disposed in a portion of a magnetic path through which the magnetic flux interlinking the coil passes. By means of a reactive force acting on the magnet on the basis of an eddy current generated in a direction hindering a change in the magnetic flux from the magnet on the one main surface of the moving body, the magnet 3 moves along an axis in the movement direction of the moving body at a speed that is lower than the movement speed of the moving body.
