Patent ID: 7812500

Claim:
An electrical generator and/or motor comprising: a can; an axle extending into the can, the axle defining axial and radial directions within the generator and/or motor, the axle having thereon an electromagnet chassis extending radially from a medial portion of the axle, the chassis and axle rotatable independently relative to each other; a plurality of electromagnets attached to the electromagnet chassis in a radial array, each electromagnet having an elongated body disposed parallel to the axle, each electromagnet body having at least one end extending axially from the electromagnet chassis; each electromagnet body having a winding portion and at least one winding disposed about the winding portion; each electromagnet further having at least one projection portion extending axially out beyond each end of the electromagnet body, each projection portion having at least one air gap surface oriented axially, with at least two opposing air gap surfaces at each end of the electromagnet body; a plurality of rings of magnets disposed radially about the shaft in electromagnetic communication with each air gap surface, each ring of magnets disposed in a position selected from radially outward from the projection portion of the electromagnet and radially inward from the projection portion of the electromagnet; each of the rings of magnets further disposed axially from the winding portion of each electromagnet.
