Title:
NON-CONTACT GENERATOR
Document Type and Number:
Japanese Patent JP2017005877
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a non-contact generator which improves magnetic efficiency and also reduces leakage of a magnetic flux.SOLUTION: A non-contact generator 1 comprises: a magnet 3 which is disposed oppositely while being separated from one principal surface of a mobile that moves in both directions of one direction and a direction opposite to the one direction, and freely movable along an axis extending in a moving direction of the mobile and generates a magnetic flux that passes one principal surface; a coil 4 which is disposed separately from a surface of the magnet at an opposite side of the surface opposing one principal surface and with which the magnetic flux from the magnet is interlinked; and a magnetic flux guide member 5 disposed in a part of a magnetic path in which the magnetic flux interlinking with the coil passes. The magnet 3 is moved at a velocity lower than a moving velocity of the mobile in the moving direction of the mobile along an axis by a reaction force that acts on the magnet based on an eddy current which is generated in a direction disturbing a change of the magnetic flux from the magnet on one principal surface of the mobile.SELECTED DRAWING: Figure 1
