Abstract
Electrically-conductive, segmental, slot wedges, with electrically-conductive inserts therebetween, and electrically-conductive interconnects, between end ones of the wedges and the annular, end retaining ring, of a rotor, define an amortisseur winding for the rotor. The inserts are spring-loaded in end slots formed in the wedges, and in an embodiment of the invention, are formed of beryllium copper and are silver-plated. As is typical of rotors in electrical, rotating equipment, the slot wedges are formed of aluminum.
