Abstract: An integral oil pump for an apparatus having a plurality of bearings, the oil pump comprising a housing with an opening for a shaft, a cavity within the housing, a ring gear encircling the shaft with clearance between the shaft and an inner surface of the ring gear, a plurality of evenly spaced keyways in the inner surface or the ring gear, a plurality of protrusions extending from the shaft that fit into the keyways to rotate the ring gear when the shaft is rotated, a floating gear meshing with the ring gear, the cavity enclosing the gears with very little clearance between the cavity and the gears, an inlet portion of the cavity adjacent the area where the gears mesh, an outlet portion of the cavity adjacent the area on the other side of where the gears mesh, an inlet port in fluid communication with the inlet portion of the cavity and an oil reservoir, an outlet port in fluid communication with the outlet portion of the cavity and with the bearings to supply pressurized oil to the bearings.

Abstract: A rectifier assembly for use in a rotating electromagnetic machine includes an outer heat sink and an inner heat sink. The outer heat sink is configured to be connected with a diode wheel rim such that an air space is defined therebetween for cooling during rotation of the diode wheel rim. At least one rectifier element is disposed between and electrically connected with the outer heat sink and the inner heat sink. A block is disposed adjacent to the outer heat sink generally opposite the at least one rectifier element. A clamping bolt extending through the inner heat sink and the outer heat sink is threadingly engaged with the block. An electrically insulating tube is disposed around the clamping bolt. An elastomeric spacer is positioned around the clamping bolt on an end of the tube. The spacer is configured to accommodate axial stack-up tolerances of the rectifier assembly in an axial direction of the clamping bolt.

Abstract: A permanent magnet rotor for an electric generator or motor has a core lamination hub formed of a stack of generally round plates with peripheral slots for holding the first end of a rectangular magnet. Each magnet has an outer end which is held by a slotted pole piece formed of laminated plates. First and second side plates overlie each side of the hub, magnets and pole pieces, and fasteners such as rivets are passed through holes in the side plates, hub plates and pole pieces to form a rigid rotor in which each rectangular magnet is supported and restrained on all six sides. A method for fabricating the rotor is also disclosed.
