Abstract
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.
