HOLLOW MAGNETIC METAL CORE PULSE ENERGY HARVESTING GENERATOR

摘要

This invention relates to energy harvesting of electrical energy by the change in a magnetic circuitous permeability path for magnetic lines of force that move through a coil of wire to induce, by Faraday's Law of Electromotive Induction, an electromotive force at the coil winding terminals of an associated coil. An abrupt, substantially instant change generated by a magnet's axial or angular mechanical and magnetic contact or dislocation through instant movement of the magnet by magnetic unlike pole spring back attractive force action with a high permeability stationary hollow or solid magnetic metal core centered in a coil bobbin with a wire wound wire coil providing efficient electrical generation therefrom.

主权项

1. An electrical generator, comprising:
a coil support; a core comprising a high permeability member extending along an axis and comprising a first axial and a second axial end, and retained within said support; a magnet having a surface substantially engaging at least one of said core first axial and said second axial end and retained thereon by magnetic attraction from one of an N and a S pole of the magnet; an elongated push member extending substantially parallel said core and movable in and retained by said coil support and disposed to receive a substantially axial force and to provide said axial force applied to said magnet, wherein
said magnet is releasable from said core by said applied axial force directed outward from said core resulting in a change in magnetic flux through said core upon release from said core and movement therefrom, and whereinsaid push member is disposed to limit separation of said magnet from said core at a maximum distance sufficient to allow said magnetic attraction to draw said magnet to said core upon withdrawal of said substantially axial force; anda coil disposed about said core providing an electrical signal in response to said change in magnetic flux.
