Entropy transferred by aging process in electric motors

In this study, motor bearing degradation is formed under the accelerated aging processes. Normal and aged motor cases are compared through the vibration measurements. These vibration signals are analyzed to extract the aging features by the statistical parameters. Hence, probability values of the healthy and faulty motor cases are defined and then, entropy value, which is transferred from the healthy (initial) case to faulty (aged) case, is calculated in the sense of the Shannon's Entropy.
