Patent ID: 7520189

Claim:
An inspection system for inspecting a generator including a rotor and a stator substantially surrounding said rotor, said rotor having a first end with a first circumference and a second end with a second circumference, said stator including a plurality of stator slots, said inspection system comprising: a first retaining ring structured to be disposed at or about the first end of said rotor; a second retaining ring structured to be disposed at or about the second end of said rotor distal from said first retaining ring; a first motion control module movably coupled to said first retaining ring; a second motion control module movably coupled to said second retaining ring, said second motion control module being interconnected with said first motion control module; electrical equipment; and a carriage assembly structured to transport at least some of said electrical equipment within said generator and between said first motion control module and said second motion control module, in order to perform an operation on said generator, wherein each of said first motion control module and said second motion control module is structured to receive said carriage assembly and to move around a corresponding one of said first circumference of the first end of said rotor and said second circumference of the second end of said rotor, respectively, in order to align said carriage assembly with a predetermined one of said stator slots of said stator of said generator.
