Sistema supervisório para monitoramento térmico de motores elétricos

Abstract

Electric motors are increasingly inserted in the manufacturing environments, as well as they are part of an important process in the industry and are fundamental for the operation of the plants, that is why a differentiated care with these equipments is required. A planned maintenance is necessary so that there are no unforeseen events that lead to production stoppage, lack of availability and possible equipment losses. Supervisory systems are developed softwares that have this ability to monitor, control and diagnose the situation of an equipment, preventing the worst scenarios from happening. One of the tools used for the development of supervisory system is LabVIEW, which has the ability to communicate through a wireless module connected to thermocouples installed in a three-phase induction motor. It has the ability to interact with the operator, creation of a precise and updated database and the competence to monitor for several periods. The results of this monitoring result in graphs with temperature behavior in a certain period of time and with the possibility of creation of reports for analysis, as well as a detailed study of the situation of the equipment, being able to facilitate the assembly of a more efficient maintenance plan and that allows its equipment not to lose the availability during its operation time.
