Abstract

This disclosure relates in general to a new and improved system for producing electric energy or mechanical power, and in particular to an improved system and method for producing rotary motion from an electro-magnetic motor or generating electrical power from a rotary motion input by concentrating magnetic forces due to electromagnetism or geometric configurations.

First claim

What is claimed is:

1. A system of producing DC voltage, the system comprising:

a first means for concentrating similarly polarized magnetic flux forces within an interior of the partial toroidal magnetic cylinder to create a first area of magnetic concentration, where the first means for concentrating comprises:
a first means of providing a plurality of similarly polarized magnetic flux forces directed at the interior and having a first length that is parallel to the longitudinal axis,
a second means of providing a plurality of similarly polarized magnetic flux forces directed at the interior and facing the first means and having a second length that is parallel to the longitudinal axis,
a third means of providing a plurality of similarly polarized magnetic flux forces directed at the interior and having a third length that is transverse to the longitudinal axis,
a fourth means of providing a plurality of similarly polarized magnetic flux forces directed at the interior and facing the third means,
wherein the first length is greater than the third length;
a 360 degree rotation path comprising at least the interior of the toroidal magnetic cylinder and an area outside of the interior of the toroidal magnetic cylinder;
a first coil segment;
a means for rotating the first coil segment through the interior of the interior of the partial toroidal magnetic cylinder; and
a means for removing the voltage from the first coil segment as the first coil segment rotationally moves through the first area of magnetic concentration.

2. The system of claim 1 further comprising a second coil segment and a means for removing the voltage from the second coil segment as the second coil segment rotationally moves through the first area of magnetic concentration.

3. The system of claim 2 further comprising an additional coil segment and a means for removing the voltage from the additional coil segment as the additional coil segment moves rotationally through the first area of magnetic concentration.

4. The system of claim 1 , wherein the first means of providing a plurality of similarly polarized magnetic flux forces directed at the interior further comprises: a first magnet means positioned along an interior wall of the partial toroidal magnetic cylinder having at least one magnet with a first common pole facing towards the interior of the partial toroidal magnetic cylinder.

5. The system of claim 4 , wherein the second means of providing a plurality of similarly polarized magnetic flux forces directed at the interior further comprises: a second magnet means positioned along an interior wall of the partial toroidal magnetic cylinder having at least one magnet with a second common pole facing towards the interior of the partial toroidal magnetic cylinder, wherein the first common pole and the second common pole have the same magnetic polarity.

6. The system of claim 5 , wherein the third means of providing a plurality of similarly polarized magnetic flux forces directed at the interior further comprises: a third magnet means positioned along an interior wall of the partial toroidal magnetic cylinder having at least one magnet with a third common pole facing towards the interior of the partial toroidal magnetic cylinder, wherein the first common pole, the second common pole, and the third common pole have the same magnetic polarity.

8. The system of claim 7 , wherein the first means for concentrating further comprises a means for creating a flux line from at least one magnet of the first, second, third, or forth plurality of magnets such that the flux line flows from the north pole of the magnet in a perpendicular manner from an interior face of the magnet, through the interior cavity of the toroidal magnetic cylinder, out an open end of the toroidal magnetic cylinder, into the open area, and then around an exterior of the toroidal cylinder to the exterior face of the magnet containing its south pole.

9. The system of claim 1 , wherein the 360 degree rotation path further comprises means for producing a magnetic field of a differing magnetic polarity in the area outside of the interior of the toroidal magnetic cylinder.

10. The system of claim 1 , wherein the 360 degree rotation path further comprises a circular core upon which one or more coil segments may be positioned around a portion of the circular core.

11. A motor comprising:
a partial toroidal magnetic cylinder positioned about a longitudinal axis,
