Abstract
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.
Claims17
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 wherein
- said 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;
- and
- a coil disposed about said core providing an electrical signal in response to said change in magnetic flux.
An electrical generator, comprising:
- a coil support;
- a core comprising a high permeability hollow substantially tubular magnetic metal member extending along an axis and including an aperture therethrough 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 a N and a S pole of said magnet;
- a magnet rotation member angularly movable with respect to said core axis and movably retained by said coil support and disposed to receive a substantially oblique force and to provide an axial force to said magnet, wherein
- said magnet is releasable from said core by said applied substantially oblique force resulting in a change in magnetic flux through said core upon release from said core and movement therefrom, and wherein
- said magnet rotation 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;
- and
- a coil disposed about said core providing an electrical signal in response to said change in magnetic flux.
