[en] The failures in diagnostics for monitoring condition of rotation machinery in the industry are very important to ensure production efficiency and safety. Moreover, these failures can cause serious malfunctioning to the machine and therefore a large lack in production. In this domain, infrared thermography is a technique that has been used frequently as a predictive tool for the maintenance of electrical installations. In fact, the most important installation faults lead to an increase of temperature in specific areas. This work presents a methodology based on thermographic image for fault detection in induction motors and the repercussion of these faults along the production chain, but due to the type of mechanical failure caused by misalignment in infrared technology there is a heating of rotating machine.
