Abstract
An inspection system inspects the interior of the stator of an electric generator for the existence of several problems. The inspection apparatus is mounted on a carriage that travels along the slots defined by the stator. An indexer is mounted to the rotor of the generator and can travel around the circumference of the rotor to deliver the carriage to the desired slot. An indexer plate is mounted to the indexer and can be registered with the desired slot to insure that the carriage can enter the slot from the indexer. An associated motor controller disables the motor if an electrical fault is disclosed.
