Resistor support assembly with spring seat

An resistor support housing for a rotating rectifier assembly (RRA), comprising:

• an annular body including a shaft bore defined therethrough for passage of a shaft of an electrical machine along a shaft axis, the body having a first annular end portion and a second annular end portion extending axially from the first annular end portion;
• and
• an annular end housing defining a second shaft bore therethrough, the annular end housing -configured to be press fit to the second annular end portion of the annular body, wherein with the annular body and the annular end housing press fit together, a joining interface is formed between the second annular end portion of the annular body and the annular end housing, wherein, an anti-rotation feature is defined within the joining interface including a notch formed within the second annular end portion and a tab extending from the end housing portion configured to be inserted into the notch,
• wherein the annular body is of a first material that is electrically conductive, and wherein the annular end housing is of a second material, different than the first material, with higher mechanical strength than the first material, wherein the first material is Aluminum and wherein the second material is steel.
