SPECIALIZED TESTING

Stator Wedge Analyzer (SWA) Test

Computerized wedge tightness testing is a method of precisely measuring the stator slot wedge system for its degree of tightness within the core iron wedge grooves. An automatic hammer, attached to an accelerometer, is used to tap every individual wedge. The computer measures, and compares all readings against predefined calibration parameters.
