Abstract :Normal 0 false false false EL X-NONE X-NONE MicrosoftInternetExplorer4 Based on a portable and high-resolution infrared thermographic system, this work studies the temperature measurement of the windings in a three phase electrical motor. The electrical machine operated under two scenarios, without load and under full-load conditions. The full-load scenario presents considerably higher temperatures and requires more time in order to reach a steady temperature state. In order to evaluate how an overload condition affects the temperature of the windings, we tested the machine under 10% overload for 15 minutes and the results proved that the temperature increases rapidly not only in the windings but also in the whole machine.Keywords : Thermography, Electric motor, Overload, Fault diagnostics.
