INSPECTION PROCEDURE FOR ROTATING ELECTRIC MACHINE, ROTATING ELECTRIC MACHINE, AND INSPECTION SYSTEM FOR ROTATING ELECTRIC MACHINE

摘要

There is provided an inspection method for a rotating electrical machine, comprising: a first step in which a first image is captured by imaging a pattern formed on an outer peripheral surface of a retaining ring attached to an axial end portion of a rotor core of the rotating electrical Machine is mounted over the entire circumference of the retainer ring using an image pickup member mounted on a non-rotating portion of the rotary electric machine in a state in which the retainer ring is rotated; a second step in which a second image is captured by imaging the pattern over the entire circumference of the retaining ring using an image pickup element in the state in which the retaining ring is rotated, the second step being carried out after the first step, an operation of rotating electric machine is interposed therebetween; and a third step in which a distortion distribution of the retaining ring is detected on the basis of the first image and the second image.
