Title:
非接触発電機
Document Type and Number:
Japanese Patent JP6567331
Kind Code:
B2
Abstract:
The invention relates to a non-contact power generator, comprising a magnet opposed at a distance to a main surface of a moving body that moves in one direction and an direction opposite to the one direction, the magnet being movable along a shaft that extends in the moving direction of the moving body, and the magnet generating a magnetic flux that passes the main surface; a coil disposed at a distance from a surface of the magnet that faces away from the main surface of the moving body, the coil being linked with the magnetic flux from the magnet; and a magnetic flux guide member disposed in at least a part of a magnetic path of the magnetic flux linked with the coil, wherein the magnet is moved along the shaft in the moving direction of the moving body at a speed lower than a moving speed of the moving body by a reaction force acting on the magnet on a basis of eddy currents generated in the main surface of the moving body in such a direction as to hinder a change of the magnetic flux from the magnet.
