Abstract

An electrical generator, comprising: a stator having a coil and a lift magnet coupled by a lever to an induction magnet, the induction magnet moveable longitudinally within the coil, the lever configured to move the induction magnet a multiple of a distance that the lift magnet is moved; and, a rotor moveable with respect to the stator, the rotor having a rotor magnet, the rotor magnet and the lift magnet positioned with respective magnetic moments opposing; whereby movement of the rotor magnet toward the lift magnet causes the lift magnet to move away from the rotor magnet which in turn causes, by operation of the lever, the induction magnet to move within the coil to generate a first electromotive force therein.

Claims

1. An electrical generator, comprising:

a stator having a lift magnet coupled by a lever to one of an induction magnet and a coil to move longitudinally and relatively the one of the induction magnet and coil to which the lever is coupled, the lift magnet moving in a same direction as the one of the induction magnet and the coil, the lever configured to move the one of the induction magnet and the coil a multiple of a distance that the lift magnet is moved using, respectively, a connecting rod coupling the lift magnet and a guide rod coupling the one of the induction magnet and the coil to the lever and wherein the lever is pivotally connected to the stator; and

,

a rotor moveable with respect to the stator, the rotor having a rotor magnet, the rotor magnet and the lift magnet positioned with respective magnetic moments opposing;

whereby movement of the rotor magnet toward the lift magnet causes the lift magnet to move away from the rotor magnet which in turn causes, by operation of the lever, the relative movement of the induction magnet and the coil to generate a first electromotive force therein.

2. The electrical generator of claim 1, wherein the lift magnet and the induction magnet are configured to move vertically on the stator and the stator is positioned over the rotor;

whereby movement of the rotor magnet horizontally toward the lift magnet causes the lift magnet to move upward on the stator and away from the rotor magnet which in turn causes, by operation of the lever, the induction magnet to move upward within the coil to generate the first electromotive force therein; and

, whereby movement of the rotor magnet horizontally away from the lift magnet causes the lift magnet to move downward on the stator due to gravity which in turn causes, by operation of the lever, the induction magnet to move downward within the coil to generate a second electromotive force therein.

3. The electrical generator of claim 1, wherein the rotor magnet moves in a plane perpendicular to a longitudinal axis of the stator.

4. The electrical generator of claim 1, wherein the coil is a wire helically wrapped around a tube.
