Dynamoelectric machine examination device, dynamoelectric machine examination system, and dynamoelectric machine

A rotary electric machine examination device for examining a rotary electric machine having an annular stator and a rotor rotatably provided on an inner surface side of the stator, the rotary electric machine examination device comprising:

• a first base unit and a second base unit respectively attached to one and another of rotor retaining rings respectively fixed to both end sides in an axial direction of the rotor;
• a guide wire stretched between the first base unit and the second base unit;
• an inspection unit including a housing of which both side surfaces are restricted by the guide wire, and a sensor unit which is attached to the housing and measures the rotor, the inspection unit being movable in the axial direction on the stator;
• and
• a driving rope of which one end is attached to the housing and which drives the inspection unit along the axial direction, wherein
• the guide wire is stretched such that a distance between the guide wire and a rotation axis of the rotor at positions of the first base unit and the second base unit is greater than a distance between the guide wire and the rotation axis of the rotor at a position of the inspection unit.
