Abstract: A disclosed terminal block assembly for a generator includes a terminal block with a base with first and second transverse terminal surfaces adjoining one another. One of the terminal surfaces includes an increased width greater than a length of a cable terminal lug for providing a lightning strike and creepage barrier. The terminal surfaces include spaced apart protrusions extending from the first and second surfaces to provide spaced apart terminal areas overlapping the first and second surfaces. First and second terminal studs are disposed within each corresponding first and second terminal areas and are electrically connected by a bus bar.

Abstract: An assembly comprises a resistor plate for a rotating rectifier assembly (RRA). A shaft bore is defined through the resistor plate for passage of a shaft of an electrical machine, and the resistor plate defines a main annular body around the shaft bore. A first protrusion extends radially outward from the main annular body, so that a first pin bore extends through the first protrusion. At least one contact band is seated in a the pin bore of the resistor plate for mounting a direct current (DC) pin to the resistor plate.

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 terminal assembly includes a terminal block of a dielectric material defining a plurality of bores therethrough. A respective terminal contact of an electrically conductive material is seated in each of the respective bores. The terminal contact defines a longitudinal axis therethrough with a terminal bore defined through the terminal contact along the longitudinal axis. A divider wall separates the terminal bore into a solder cup for a lead wire on an interior side of the terminal bore, and a lug receptacle on an exterior side of the terminal bore.

Abstract: A variable frequency generator (VFG) rotor can include a plurality of windings configured to form a plurality of magnetic poles, each winding comprising a first winding end and a second winding end, and a first winding support structure comprising a plurality of first winding support segments configured to retain a first portion of each winding, each winding support segment being configured to move radially relative to an axis of rotation of the rotor. The first winding end of each winding extends from each winding support segment. The rotor can include at least one flexible bus bar jumper connected to two first winding ends of adjacent windings and configured to flex with radial movement of the winding support segments of respective windings attached to the flexible bus bar jumper.
