Beschreibung
Zusammenfassung:	A system and method for determining wedge tightness in a dynamoelectric machine is provided. The dynamoelectric machine includes a rotor, stator and a wedge assembly having at least one wedge for retaining a coil. The system includes a force application device for applying a predetermined force or a known quantity of force to a wedge, and the force is applied in a substantially radial direction. A measuring device for measuring movement of the wedge, measures a movement distance relative to a surface of an adjacent core surface. The system can be inserted between the rotor and the stator, and the movement distance is obtained by evaluating a distance to an adjacent core surface and a distance to a surface of the wedge.
