Abstract

This study, titled Comparative Evaluation of Machine Learning Models for Fault Detection in Induction Motors presents a comparative evaluation of machine learning (ML) models for fault detection in three-phase induction motors, which are essential components in industrial applications. Despite their robust construction, these motors are prone to faults such as stator winding failures, rotor defects, and overvoltage conditions that can cause unexpected breakdowns and operational losses. Traditional fault detection techniques often lack the sensitivity and consistency required for early fault detection. To address this gap, this research investigates the effectiveness of four supervised ML algorithms—Random Forest (RF), K-Nearest Neighbors (KNN), Gradient Boosting Machine (GBM), and Support Vector Machine (SVM). A 7.5?kW induction motor was modeled using MATLAB/Simulink, simulating six operating conditions to generate relevant datasets. These were preprocessed and evaluated in Pytorch using standard classification metrics: accuracy, precision, recall, and F1-score. Among the models, Random Forest delivered the best performance with an average accuracy of 94.7%, precision of 93.7%, recall of 92.7%, and F1-score of 93.2%. GBM followed closely with an accuracy of 92.0% and F1-score of 90.5%, while SVM achieved moderate results. KNN showed the lowest performance across all metrics. The results confirm Random Forest as the most robust and reliable model for industrial motor fault detection.
