Abstract

A rotating flux transformer having at least two magnetic cores, each in the form of a torus, with each magnetic core having poloidal and toroidal windings. The need for breaking the torus and bringing out leads from the poloidal winding is eliminated by passing each torus through the core window of the remaining torus, or tori. Each poloidal winding is shorted, with the toroidal winding, or windings, of the other magnetic core or cores, inducing an excitation voltage into each shorted poloidal winding which is 90.degree. out of phase with the voltage applied to the toroidal winding on the same magnetic core.
