Políticas organizacionais de redução de custo de manutenção: análise da viabilidade de implantação de supressores de surto para mitigação de queimas e falhas de equipamentos eletrônicos em uma empresa de motores elétricos

Abstract

The main objective of this study is to analyze the feasibility of implementing surge suppressors to mitigate burns and failures of electronic equipment of an electric motor manufacturer. The research approach was quali-quantitative, based on field research based on the case study. Based on a sample of more than 5,000 pieces of equipment and an analysis of the data, the criteria for selecting the 70 pieces of equipment were maintenance costs with values above R $ 10,000.00, the worst MTBF – average time between failures, in the last 12 months. Our main focus is to analyze the feasibility of implementation as a result, it is also expected to improve equipment availability by 5%. The results obtained with the use of surge suppressors in the equipment showed a 60% reduction in maintenance material costs and a 50% reduction in machine downtime, providing a real gain in 2019 of 250 thousand reais. In view of the results obtained, it was shown that the implantation of surge suppressors was feasible, not only in the 70 equipments, but also in new equipments with significant embedded electronics or of high criticality for the process, they should already come with the surge suppressors, mitigating the costs with problems such as burns and electronic failures.
