Abstract:
1. A DC electromagnetic generator device comprising: a radially magnetized rotor within a radially magnetized toroidal magnetic stator core; at least one toroidal winding section toroidally wound about at least a portion of said magnetic stator core, and having an output terminal; an input shaft; and a permanent magnet mounted to said input shaft for rotating said rotor, said input shaft and said rotor being located substantially within said stator, and whereby a magnetic field generated by said permanent magnet rotor passes through said toroidal winding section and onto said radially magnetized toroidal magnetic stator; wherein said at least one toroidal winding section extends into one but not both of a north pole or a south pole of said stator's magnet, such that the coils of said stator winding structure are exposed to a moving magnetic flux field of either a north pole or south pole of said rotor at any instant in time such that one or more magnetic flux fields generated by said stator winding extend in the same direction within said stator core, whereby essentially all of the magnetic flux fields generated by the toroidal winding section are confined within said toroidal stator core such that there is essentially no magnetic field leaving the magnetic stator core; said magnetic stator core, winding section and permanent magnet being configured to generate electrical power.
