Abstract
A homopolar inductor-alternator machine is constructed to have lower transient rectances by the incorporation of a current conducting ring concentric with the axis of the rotor and positioned on the rotor and/or the stator. The conducting ring helps prevent time varying fluxes from inducing eddy current flow in the high permeability rotor steel and unlaminated stator flux return path (back iron). The conducting ring acts upon the transient fluxes which occur in the DC flux path of the machine.
