Rotating machine configurable as true DC generator or motor

A rotating machine operable as a DC generator or motor comprising:

• a support assembly, including a shaft and a pair of bearings;
• a pair of rotating ferrous metal hubs mounted to the outside of the support assembly;
• a stationary coil consisting of a single length continuous conductor element wrapped repeatedly around a toroidal ferrous magnetic core having a rectangular cross section, the coil being disposed around the support assembly and inside of the rotating hubs;
• a pair of magnets, each magnet being mounted on an inside surface of one of the rotating hubs and being aligned such that a first of the pair of magnets faces a side of the coil and a second of the pair of magnets faces an opposite side of the coil, each of the pair of magnets having a same magnetic polarity facing the coil such that magnetic flux from each magnet cuts the conductor element of the coil in a same direction when the hubs rotate;
• a first ferrous metal toroid attached to the first magnet and positioned between the first magnet and the coil, a second ferrous metal toroid attached to the second magnet and positioned between the second magnet and the coil, an inner ferrous metal toroid attached to an inner circumference of the coil, an outer ferrous metal toroid attached to an outer circumference of the coil;
• and
• means for carrying the direct current from or to the conductor element of the coil.
