AC generator exciter rotor slip-ring test apparatus

A test apparatus assembly for testing an AC generator having an exciter rotor mounted to a shaft, the apparatus comprising:

• an annular end bell having an outer peripheral surface, an inner peripheral surface defining an opening configured to receive the shaft, and a channel extending between the outer and inner peripheral surfaces;
• a carbon brush assembly coupled to the end bell inner peripheral surface, the carbon brush assembly comprising:
• a housing coupled to the end bell inner peripheral surface;
• at least a conduit formed in the housing in communication with the channel;
• a spring-loaded carbon brush disposed in the conduit;
• and
• a wire connector coupled to the carbon brush and extending through the channel;
• and
• a slip ring assembly configured to be mounted to the shaft and to at least partially contact the carbon brush, the slip ring assembly comprising:
• a hub configured to couple to the shaft, the hub including an outer peripheral surface and a cavity extending therethrough;
• a first slip ring coupled to the hub outer peripheral surface;
• and
• a wire connector coupled to the first slip ring and extending through the hub cavity, the wire connector configured to electrical couple the first slip ring to the exciter rotor.
