Abstract
An inspection apparatus of an embodiment includes a rotor image-pickup unit for picking up an image of a rotor using a rotor image-pickup device in the air gap between the rotor and a stator. The rotor image-pickup device includes: a carriage casing; a camera; an image-pickup position changing part; and an image-pickup direction changing part. The camera is installed in the carriage casing, and picks up an image of a ventilation hole of the rotor in the air gap. The image-pickup position changing part is installed in the carriage casing, and changes an image-pickup position of the camera by moving the carriage casing in a circumferential direction of the rotor in the air gap. The image-pickup direction changing part is installed in the carriage casing, and changes an image-pickup direction of the camera to an inclined angle to a radial direction of the rotor in the air gap.
