Inspection device for rotating electric machine and method of inspecting rotating electric machine

An inspection device for a rotating electric machine, comprising:

• at least one image pickup apparatus disposed within the rotating electric machine and configured to capture at least one image of a measurement target portion set on an outer surface of a rotor included in the rotating electric machine;
• a storage circuitry to store tendency information indicating a relationship among a position of damage that occurs in an inspection target portion being a range to be inspected of the rotor included in the rotating electric machine, a scale of the damage, and an amount of deformation that occurs in the measurement target portion set on the outer surface of the rotor;
• a measurement circuitry to measure the amount of deformation that has occurred in the measurement target portion based on the at least one image captured by the at least one image pickup apparatus;
• and
• a damage estimating circuitry to estimate the position and the scale of the damage that has occurred in the measurement target portion based on the tendency information and the amount of deformation in the measurement target portion, which has been measured by the measurement circuitry,
• wherein the inspection target portion is located in an area of the rotating electric machine that is not visible without disassembly of the rotating electric machine.
