Abstract: An electrical device has a capacitive storage element and first and second switches. The capacitive storage element and first and second switches are interconnected such that when interconnected with a direct current (dc) voltage supply and first and second windings of an electrical machine: (1) a first operational state exists in which conductive states of the first and second switches cause the dc voltage supply to conduct current through the first winding and the first switch and conduct current through the first and second switches and the second winding, respectively, thereby storing energy within the first and second windings, and (2) a second operational state exists in which non-conductive states of the first and second switches cause each of the first and second windings to discharge stored energy by conducting current through the capacitive storage element, thereby storing energy in the capacitive storage element.

Abstract: An electrical machine rotor includes a flux-conducting portion and a flux-inhibiting portion. The flux-conducting portion is conducive to conveying an electromagnetic flux and has a plurality of salient rotor poles and a portion of back material. The flux-inhibiting portion is less conducive to conveying an electromagnetic flux than the flux-conducting portion and is disposed entirely outside the boundaries of the rotor poles.
