Abstract :
In this study, statistical behavior of vibration test data-acquired from seven accelerated aging processes undertaken for a three-phase, 5 HP, squirrel-cage induction motor-is examined. An early fault detection level, together with an experimental aging model, is determined for the motor bearings. Time-frequency presentations of the initial and aged cases are shown.
