Predictive maintenance with NOA: Application and insights for rotating equipment

Smart Predictive Maintenance Device for Critical In-Service Motors

“…The technological development of the last decades [6,7] has made the share of corrective and reactive maintenance (intervention after occurrence, respectively at the manifestation of a fault) or even preventive (performed periodically) within the maintenance service to be significantly reduced in the favor of predictive. The latter continuously compares the most important operating parameters trend values for electrical, thermal, and mechanical quantities of investigated equipment with their accepted limits [8][9][10]. This enables the detection, analysis, and even correction of various malfunctions before they manifest (avoiding the appearance of a defect) [7,8,10].…”

This enables the detection, analysis, and even correction of various malfunctions before they manifest (avoiding the appearance of a defect) [7,8,10]. These significant investigations capabilities were mainly feasible due to the increased computing power [7,9].…”

“…Consequently, a non-comprehensive approach can lead to inefficient actions in terms of maintenance and diagnosis of the machine unproper functionality. Thus, the most suitable investigation could only be achieved from the integrative interpretation analysis adequately correlated with visualization of all monitored parameters [10,11]. Some other maintenance principles are based on the insulation aging detection [12] or bearing fault signaling [13].…”
