Patent ID: 8370086

Claim:
A system for determining wedge tightness in a dynamoelectric machine, the dynamoelectric machine comprising a rotor, stator and a wedge assembly having at least one wedge for retaining a coil, the system comprising: a force application device for applying a predetermined force to a wedge, the force applied in a substantially radial direction; a measuring device for measuring movement of the wedge, the measuring device comprising a first linear voltage displacement transducer (LVDT) configured to measure a distance to an adjacent core surface and a second LVDT configured to measure a distance to a wedge surface, wherein a wedge movement distance is measured relative to a surface of an adjacent core surface; and wherein, the system can be inserted between the rotor and the stator, and the wedge movement distance is obtained by evaluating a distance to an adjacent core surface and a distance to a surface of the wedge.
