1. An assembly comprising:
a resistor support housing for a rotating rectifier assembly (RRA), wherein a shaft bore is defined through the resistor support housing for passage of a shaft of an electrical machine, wherein the resistor support housing defines a main annular body around the shaft bore;
an end housing mounted to the main annular body at one axial end of the resistor support housing at a joining interface via press fit, wherein the end housing defines a portion of the shaft bore therethrough; and
an anti-rotation tab extending axially from the end housing, wherein the anti-rotation tab is seated in an anti-rotation notch defined in the main annular body with the end housing mounted to the main annular body at the joining interface, wherein the anti-rotation tab is defined at least partially in the joining interface;
wherein the resistor support housing is of Aluminum, wherein the end housing is of steel.
