This paper presents an ensemble machine learning-based fault classification scheme for induction motors (IMs) utilizing the motor current signal that uses the discrete wavelet transform (DWT) for feature . classification problem as an anomaly detection problem. and ImageNet 6464 are variants of the ImageNet dataset. something to classify after all! daniel (Owner) Jaime Luis Honrado (Editor) License. Failure Mode Classification from the NASA/IMS Bearing Dataset. During the measurement, the rotating speed of the rotor was varied between 4 Hz and 18 Hz and the horizontal foundation stiffness was varied between 2.04 MN/m and 18.32 MN/m. Waveforms are traditionally signals (x- and y- axis). Rotor and bearing vibration of a large flexible rotor (a tube roll) were measured. We will be keeping an eye post-processing on the dataset, to bring it into a format suiable for return to more advanced feature selection methods. The vertical resultant force can be solved by adding the vertical force signals of the corresponding bearing housing together. We have built a classifier that can determine the health status of The dataset is actually prepared for prognosis applications. Data. As shown in the figure, d is the ball diameter, D is the pitch diameter. The test rig and measurement procedure are explained in the following article: "Method and device to investigate the behavior of large rotors under continuously adjustable foundation stiffness" by Risto Viitala and Raine Viitala.
