Özet

This study is focused on the redundant wavelet transform application for vibration signals collected from induction motor of 5 HP aged under the accelerated aging processes. For this purpose, comparing the healthy and faulty cases of the motors, some inherent advantages of the redundant transform over the un-redundant one is extracted. This possibility can be provided by means of the Continuous Wavelet Transform (CWT) because it is a redundant transform. Hence some failure properties of the motor bearings can be shown by initial case of the motor before the aged case. This is most important and powerful side of this study and then, failed motor case can be easily tracked by help of this approach.
