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.

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.

A rotating rectifier associated with an electric machine is provided. In one example aspect, a rotating rectifier includes a diode. The diode can be one diode of a stage of diodes. The rotating rectifier can also include a connection lead, such an exciter connection lead. The connection lead has a diode contact segment in contact with the diode and a first spring segment and a second spring segment positioned on opposite sides of the diode contact segment. The first spring segment and the second spring segment can be positioned adjacent to the diode contact segment. The first spring segment and the second spring segment each have one or more spring laps. The spring laps can be non-planar spring laps, such as undulating spring laps.
