几十年来，红外热成像技术已广泛应用于电气设备维护等领域。它在电机中的应用主要局限于检测静态机器的故障，如电力变压器。然而，在旋转电机的预测性维护方面，它的使用受到了很大的限制。尽管如此，该工具的潜力，加上红外摄像机价格的逐步下降，使该技术成为一个非常有趣的选择，至少可以补充其他知名技术（如电流或振动数据分析）提供的诊断。在这种情况下，红外热成像最近显示出检测电机故障的潜力，包括不对准、冷却问题、轴承损坏或连接缺陷。这项工作提出了几个工业案例，有助于说明该技术在现场感应电动机中广泛故障检测的有效性。用这种技术获得的数据可以检测到各种性质的故障（电气、机械、热和环境）；这些数据对于诊断或补充其他工具提供的诊断非常有用。
Infrared thermography has been extensively applied over decades to areas such as maintenance of electrical installations. Its use in electrical machinery has been mainly circumscribed to the detection of faults in static machines, such as power transformers. However, with regard to the predictive maintenance of rotating electrical machines, its use has been much more limited. In spite of this fact, the potential of this tool, together with the progressive decrease in the price of infrared cameras, makes this technique a very interesting option to at least complement the diagnosis provided by other well-known techniques, such as current or vibration data analysis. In this context, infrared thermography has recently shown potential for the detection of motor failures including misalignments, cooling problems, bearing damages, or connection defects. This work presents several industrial cases that help to illustrate the effectiveness of this technique for the detection of a wide range of faults in field induction motors. The data obtained with this technique made it possible to detect the presence of faults of diverse nature (electrical, mechanical, thermal, and environmental); these data were very useful to either diagnose or complement the diagnosis provided by other tools.
