Abstract: The present disclosure, in one form, provides an electric motor/generator low hydraulic resistance cooling mechanism including a hollow cooling stator case having an inner and outer coaxial surface. The inner surface defines a generally cylindric cavity for receiving a stator in heat transference contact with the inner surface. The outer surface has integrated spiral groove cooling passages that are defined by filleted rectangular cross sections.

Abstract: The present disclosure is directed to a fluid-cooled housing for an electric device having an outer surface and an inner surface, the inner surface defining, at least in part, a housing cavity having a longitudinal axis, an end wall continuous with the inner surface. The inner surface having a plurality of core print openings along the longitudinal axis, and a helical conduit integrated within the housing between the outer and inner surfaces along the axis formed from a helical coil core having two or more laterally extending tabs which form the core print in two or more planes.

Abstract: The present disclosure is directed to a terminal assembly member for electrically connecting output leads to external systems and equipment, including a one piece insulating body formed from high-pressure molten plastic/nylon, adapted for mounting to an external portion of a generator housing; one or more conductive inserts over-molded within the one piece insulated body, the conductive inserts having at least one threaded bore for receiving a bolt; and one or more bronze alloy lug structures over-molded within the one piece insulated body, the one or more lug structures having a generally L-shaped geometry and a plurality of bores adapted for attaching terminal ring carriers.

Abstract: A variable reluctance machine is disclosed, such as a switched reluctance machine, the machine having a rotor, a stator, a housing, and a magnetic eddy current dampening component disposed between stator and housing. The magnetic eddy current dampening component not only reduces the eddy current's impact on surrounding electronics, it also assists in increasing the efficiency of the switched reluctance machine.

Abstract: The present disclosure provides a fluid-cooled housing for an electric device having a housing. The housing includes an outer surface and an inner surface, the inner surface defining, at least in part, a housing cavity having a longitudinal axis, an end wall continuous with the inner surface, thereby substantially enclosing the housing cavity at a first end, and a chain of cooling channels creating a serpentine pattern defined along the inner surface of the housing.

Abstract: A fluid-cooled electric device such as a generator, alternator or motor is provided with a housing that includes an outer surface defining an exterior of the device and an inner surface that defines a housing cavity with a longitudinal axis, and which may have an end wall enclosing one end of the housing cavity wherein the end wall is continuous with the inner surface. Integral to the housing is a helical cooling conduit, which may have a rectangular configuration, disposed along the axis between the inner and outer surfaces of the housing.
