Avaliação de desempenho e confiabilidade de motores elétricos em uma indústria

Abstract

This work makes an analysis of the performance and reliability of Electric Motors in an industry, evaluating the impacts caused on efficiency and productivity. The main causes for failures in these equipments were evidenced, proposing actions to improve the performance and control of electric motors. First, the manufacturing data of a motor was colected by its nameplate, as well as a review of the operating principles of three-phase induction motors. Next, the main causes of failure in electric motors were identified, based on the operation in an industry. The concepts of Predictive, Preventive and Corrective Maintenance were also presented, showing their impacts on the proper functioning of the equipment. For this, a case study was conducted in a beverage industry, located in the city of Aquiraz/CE, where the data were collected during a year, during the development of an internship project. Finally, the results of the proposed actions that were applied in the case study are presented, where it is possible to verify that there was a 64% reduction in expenses in 2017 compared to 2016, showing that the impact of the engine management is positive, improving not only the visibility of the main causes for the failures of the motors, but also reducing costs with corrective maintenance.
