This paper focuses on analyzing motor current signature for fault diagnosis of gearboxes operating under transient speed regimes. Two different strategies are evaluated, extensively tested and compared to analyze the motor current signature in order to implement a condition monitoring system for gearboxes in industrial machinery. A specially designed test bench is used, thoroughly monitored to fully...
In this paper, a Novel approach for diagnosing gearbox faults in transient speeds using the Motor Current Signature Analysis (MCSA) is introduced. Current and speed signals were collected from the motor in ramp-up speeds under no load. For increasing the signal-to-noise ratio, a dual-level time synchronous averaging is introduced. First, the sinusoid component related to the motor supply frequency...
