Patent ID: 7592727

Claim:
A device for exerting counter-rotational influence on a rotor, said device comprising a rotational component and plural stationary components, said rotational component including plural electrically conductive wheels and an axle for being coaxially fastened to said rotor, said wheels being perpendicular to said axle and parallel to and separated from each other, each said wheel being coaxially fastened to said axle, each said stationary component including a ferromagnetic core structure and at least one ferromagnetic guidance structure, said core structure being characterized by a bracket shape and including a main core section and two projective core sections, said at least one guidance structure being fastened to said core structure so that said core structure and said at least one guidance structure together describe a generally prismatic shape having plural slots each accommodative of said wheel, each said slot being formed by the interface between two said guidance structures or by the interface between said guidance structure and said projective core section, said device being capable of engendering Lorentz forces that oppose the rotation of said rotor, said device being capable of engendering said Lorentz forces when used in a manner including the following: said axle is coaxially fastened to said rotor; each said stationary component is situated so that said main core section is parallel to said axle and so that said wheels are partially inside said slots; rotation of said rotor is activated whereby said axle and said wheels rotate together with said rotor; electrical current is caused to flow through electrically conductive wiring that is partially coiled around said core structure of each said stationary component; in each said stationary component, a closed magnetic flux path is generated through said core structure, said at least one guidance structure, and said rotating wheels; in each said wheel, electrical eddy currents are generated in association with the rotation of said wheel and the intersection of said wheel by said closed magnetic flux path of each said stationary component; in each said stationary component, a magnetic field is generated in association with the flowing of said electrical current through said wire partially coiled around said core structure; said Lorentz forces are generated in association with the interactions between said magnetic fields and said electrical eddy currents.
