1. An assembly comprising:
a resistor plate for a rotating rectifier assembly (RRA), the resistor plate including:
a shaft bore is defined through the resistor plate for passage of a shaft of an electrical machine;
a main annular body around the shaft bore;
a first protrusion extending radially outward from the main annular body, wherein a first pin bore extends through the first protrusion;
a second protrusion extending radially outward from the main annular body, wherein a second pin bore extends through the second protrusion;
at least one contact band seated in the first pin bore of first protrusion of the resistor plate for mounting a direct current (DC) pin to the resistor plate, wherein a respective joining interface formed between each of the at least one contact band and the resistor plate is free of braze; and
at least one contact band seated in a the second pin bore of the second protrusion for mounting a direct current (DC) pin to the resistor plate, wherein a respective joining interface formed between each of the at least one contact band and the resistor plate is free of braze;
a first DC pin seated in the at least one contact band of the first protrusion; and
a second DC pin seated in the at least one contact band of the second protrusion.
