Análise da redução dos custos de manutenção de motores elétricos a partir do uso de técnicas preditivas fundamentadas na manutenção centrada na confiabilidade

Abstract

Driven by market competitiveness and the need to meet increasingly demanding operational requirements, industries have been seeking cost mitigation, alongside the optimization of the availability and reliability of their systems. In this context, maintenance management emerges as a sector that offers various opportunities, with Reliability-Centered Maintenance (RCM) presenting itself as an alternative to help institutions achieve a proactive maintenance management model, reaching pre-established goals with an excellent cost-benefit ratio. RCM is based on the structured use of techniques and tools, implementing strategic maintenance actions to reduce operational costs and optimize labor effort allocation, resulting in increased system reliability and overall availability. However, the effective application of RCM requires the execution of a series of steps, from understanding the systems composing the plant to defining optimized maintenance plans, focusing on continuous process improvement. This necessitates a high level of maturity from implementation teams and company senior management. Therefore, considering the intensive development of maintenance management across generations and the unique specifics of each organization, it is justifiable to adapt the best practices of RCM to the business reality. Hence, this work provides a historical review of maintenance, highlighting the global trends that influenced maintenance management to hold the current strategic position, aiming to gather a set of actions to develop a methodology for electric motors maintenance focused on reliability, fault reduction, and efficient capital allocation in a large-scale industry.
