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.
Claims11
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.
