Abstract

See full text

A rotating electrical machine of the present invention evaluates a relative displacement of members and improves reliability further even when two or more members operate or move. A rotating electrical machine of the present invention comprises a stator and a rotor disposed on an inner side of the stator with a predetermined gap. The stator includes vibration measuring devices, each of the vibration measuring devices placed on each of at least two members included in the stator, the members having different displacements or phases with each other. The rotating electrical machine includes a device that acquires a relative displacement of one of the members included in the stator by evaluating a difference between displacements or phases measured by the vibration measuring devices and that evaluates a lifetime of the one of the members included in the stator based on the relative displacement.
