摘要： A stator testing device for a dynamoelectric machine formed from a plurality of laminations defining a plurality of substantially parallel stator teeth each extending over a preselected length of the stator. The stator testing device includes a housing having a bottom face adapted to be disposed adjacent the stator teeth and a face cover extending outwardly from said bottom face. A chattock coil for detecting stator axial currents is disposed within said housing. The chattock coil has a pair of end portions with bottom surfaces each extending to the bottom face of said housing. A pair of brackets are removably attached to the face cover of said housing, and a magnet is removably attached to each bracket. The magnets are located on the brackets so that the bottom surfaces of the pair of magnets are positioned adjacent to selected corners of adjacent stator teeth and remain in positional relationship to the selected corners as the housing is moved over a preselected length of said stator.

摘要： Apparatus for examining an elongated cylindrical body having an axial bore, such a rotor shaft, which apparatus includes an energy transducer which is supported by a drive rod to be advanced within the bore while obtaining readings indicative of the physical condition of the body, a drive unit supporting the rod, and a fixture for supporting the drive unit in order to center the drive rod within the bore, the fixture being supported by the body and including a mechanism for adjusting the fixture in order to establish the desired axial alignment of the drive rod. The fixture is provided with an arrangement for supporting a calibration block which is used for calibration of the apparatus, the arrangement being adjustable relative to the fixture to bring the calibration block into a desired position relative to the transducer when the drive unit is mounted on the fixture. The drive unit is rotated and advanced axially by DC permanent magnet motors and at least the motor which effects rotation of the drive rod is controlled by position and velocity error signals derived with the aid of a pulse encoder connected to rotate with the motor. A starting angular reference position of the body is determined with the aid of a further fixture which provides a flat reference surface having a defined orientation relative to a reference point on the body.
