ABSTRACT:
Separate multiple flux paths for an electrical generator or motor are provided in a single rotor machine by axially mounting a plurality of pole pieces on the rotor shaft. Each pole piece includes a central disc portion having a plurality of radial pole-forming projections, with the projections of adjacent pole pieces rotated 180 electrical degrees, such that the pole-forming projections of every other pole piece have the same magnetic polarity. Provision of a plurality of separate magnetic flux paths increases the total flux attainable in a machine of given size and therefore improves the machine's output and efficiency.
