Abstract
In the Three-Phase Induction Motor (3-phase IM), as in any electromechanical energy converter, the electrical input power (required from the power supply) is equal to the mechanical output power delivered to the load plus the losses inherent to the process. Even though they are intrinsically efficient devices, 3-phase IM constitute a great potential for energy conservation when energy efficiency actions are carried out in an industry. This article presents an accessible monitoring system for the various industrial segments, justifying the development of a monitoring system using low-cost, non-invasive, cloud, robust technologies that allow a simple and remote visualization of the percentage loading, which is an indicator of the efficiency of electrical machines. In this way, the characteristics of this system make it possible to use it on a large scale, that is, in the large number of motors installed in the industry, enabling the diagnosis of possible applications that require adjustments to the actuators. With the experimental results, the functionality of the developed monitoring system was verified with a percentage error of up to ±10% between percentage of the nominal loading from 82% to 110%.
