Degradation State Identification of Cracked Ultrasonic Motor by Means of Fault Feature Extraction Method
The cracking of piezoelectric ceramics is the main reason of failure of an ultrasonic motor. Since the fault information is too weak to reflect the condition of piezoelectric ceramics especially in the early degradation stage, a fault feature extraction method based on multiscale morphological spect...
