Del Vecchio, R M; Specht, T R

An electrical transformer is described comprising: first and second magnetic cores, each of the first and second magnetic cores being a closed loop which defines a core window, with each magnetic core having an outer surface surrounding a longitudinal axis and a continuous axially extending opening, first and second shorted poloidal windings disposed in the axially extending openings of the first and second magnetic cores, respectively, first and second toroidal primary windings disposed about the outer surfaces of the first and second magnetic cores, respectively, first and second sources of alternating potential connected to the first and second toroidal primary windings, respectively, with the first and second sources of alternating potential having like frequencies which are phase displaced by about 90 electrical degrees, and a first toroidal secondary winding disposed in inductive relation with a selected one of the first and second toroidal primary windings, the first and second magnetic cores being linked, with each magnetic core passing through the window of the other magnetic core, to induce a voltage in each of the first and second shorted poloidal windings which is 90/sup 0/ out of phase with the voltages applied to the first and second toroidal primary windings, respectively, wherein the magnetic fluxes in each magnetic core due to the toroidal primary winding and shorted poloidal winding produce a rotating induction vector.
