Experimental generation and quantification of stator core faults on induction motors

A non-destructive method to analyze stator core faults on induction motors is presented and developed in the present work. It allows generating entirely reversible faults of different magnitudes. The quantification of fault severity was performed through the stator core interlaminar insulation test and through no-load test. The obtained experimental results show the feasibility of the method and the detectability of generated faults, which makes it a useful method to develop new diagnosis strategies.
