Abstract: A main field connection to connect to a main field winding has a semi-cylindrical portion with an axially thicker outer surface, an axially thinner inner surface, with an aperture. An extending portion extends from the semi-cylindrical portion to a remote extending end. The remote extending end extends for a first axial distance. The axially thicker portion of the semi-cylindrical portion extends for a second axial distance. A ratio of the first axial distance to the second axial distance is between 0.65 and 1.4. A rotating assembly, a generator and a method are also disclosed.

Abstract: A resistor pack assembly including an anti-rotation housing. The anti-rotation housing includes a first surface, a second surface opposite the first surface, one or more anti-rotation lugs extending away from the first surface, and an internal cavity extending from the second surface into the anti-rotation housing towards the first surface. The resistor pack assembly also including a positive rail located at least partially within the internal cavity, a negative rail having an inner circular face and an outer circular face located radially outward from the inner circular face, and an insulator ring is interposed between the second surface of the anti-rotation housing and the outer circular face of the negative rail.

Abstract: An assembly comprises a resistor support housing for a rotating rectifier assembly (RRA). A shaft bore is defined through the resistor support housing for passage of a shaft of an electrical machine. The resistor support housing defines a main annular body around the shaft bore. An end housing is mounted to one axial end of the resistor support housing. The end housing defines a portion of the shaft bore therethrough.

Abstract: A rectifier assembly includes a terminal arranged along an assembly axis, a mounting ring axially offset from the terminal and seating a diode, a bus bar received within the mounting ring and electrically connecting the diode to the terminal through the bus bar, and a mounting ring. The mounting ring insulator receives the bus bar, is axially offset from the mounting ring, and contains an insert. The insert fixes the bus bar to the mounting ring insulator and compressively fixing the diode within the mounting ring. Generators and methods of making rectifier assemblies for generators are also described.

Abstract: An electrical machine includes a rotor including windings circumferentially spaced apart by rotor wedges. The electrical machine includes a rotor end plate mounted to the rotor. The rotor end plate includes an annular end plate body with an interior surface and axially opposed exterior surface. The interior surface includes a cavity for engaging the rotor. The interior surface has a base that is bounded by an inner rim and an outer rim radially opposite the inner rim. The interior surface is free of anti-rotation projections extending axially therefrom. The outer rim is free of anti-rotation features extending radially inward therefrom.
