“…On the other hand, in [27], an approach based firstly on the extraction of characteristics in the time and frequency domain, then the construction of a basic classifier by applying a genetic algorithm is presented. A novel method combining "Adaptive Feature Extraction" and "Multi-scale entropy" using "Support Vector Machine" (SVM) has been proposed in [28]. In the research work [29], the faults signature extraction is based on the frequency domain analysis using the envelope power spectrum.…”

This paper concerns the automatic diagnosis of ball bearing defects in industrial geared motor based on statistical indicators and the Adaptive Neuro-Fuzzy Inference System (ANFIS). The approach consists of three essential steps: the first is the extraction of statistical indicators from the root mean square (RMS) of the raw vibration signals measured experimentally for different states of the bearing (healthy and in the presence of defects). The second step consists of the selection of the more relevant indicators, and finally the introduction of these indicators to the ANFIS network in order to classify the various defects in the bearing (inner and outer race faults, and combined fault). A test campaign was conducted on an industrial installation (Wheeled Conveyor) to collect data as the RMS trend of the raw vibrations using adequate instrumentation in order to verify the validity of the method in real test conditions. The obtained results show that the proposed approach can reliably detect and classify various faults at different speeds of rotation of the electric motor. The effectiveness of the proposed method was also approved by using additional test data.
