Deformation Prophecy in Stator Windings with Modal Analysis and Fuzzy Techniques on Asynchronous Machine

Asynchronous machine (AM) failures are mainly caused by stator windings (SW); practically, all methods for identifying these faults have relied on cost. Early fault diagnosis employing an appropriate methodology could lower maintenance costs and save time. Industries should look ahead to solve sudden failures in the machines. This article identifies the precise location of deformation in the SW to avoid sudden failure and to meet industrial needs by employing experimental techniques like modal analysis (MA). The deflection shape from MA determines the deformation in the windings at points 1 and 10. The deformation at point 1 is 5.19 mm toward the rotor, and at point 10, the deformation is 28.90 mm toward the stator as determined by theoretical calculations. Furthermore, the fuzzy technique is applied using the experimental data set to examine the deformation in the machines’ SW. Fuzzy logic is used to decide whether to proceed or to replace the machine to meet industrial standards and prevent an unexpected AM interruption.
