  • Generator inspection assembly
    Patent number: 7520189
    Abstract: An inspection system is provided for inspecting a generator including a rotor and a stator substantially surrounding the rotor. The rotor has a first end with a first circumference, and a second end with a second circumference. The inspection system includes first and second retaining rings disposed at or about the first and second ends of the rotor, and first and second motion control modules movably coupled to the first and second retaining rings. The first and second motion control modules are interconnected and guide a carriage assembly therebetween in order to perform an operation on the generator. At least one of the first and second motion control modules is structured to receive the carriage assembly and to move around the corresponding first or second circumference of the generator rotor, in order to align the carriage assembly with stator slots of the stator of the generator.
