Low-Cost Thermographic Analysis for Bearing Fault Detection on Induction Motors

摘要

This paper presents a low-cost thermography approach to detect faults in ball-bearings on induction motors under industrial operating conditions. The proposed methodology applies a thermal differential technique to make the failure detectable even in changing environmental conditions. The obtained results prove that around of the 5℃ of thermal difference between the ball-bearing temperature and the surrounding environment is an indicative of a failure.
