Abstract

This paper presents the detection of broken rotor bars (BRB) in three-phase induction motors (IM) employing three supervised machine learning algorithms (SMLA), including Decision Three Classification (DTC), Artificial Neural Network (ANN), and Support Vector Machine (SVM). The three SMLAs are trained to detect BRB features from measured steady-state line current signatures. The training data were collected in the time domain from laboratory experiments and transformed to the frequency domain through the Discrete Fourier Transform (DFT). A confusion matrix was employed to confirm the models' performance by means of accuracy, precision, recall, and f1-scores. The results evidence that the DTC has better accuracy and precision for both half and full-load operations of the squirrel cage asynchronous motor when compared with the ANN and SVM algorithms. The DTC obtained the best F1 score, accuracy, precision, and recall, followed by the SVM.
