SYSTEM AND METHOD FOR BEARING FAULT DETECTION USING STATOR CURRENT NOISE CANCELLATION

摘要

A system and method for detecting incipient mechanical motor faults by wa y of current noise cancellation is disclosed. The system includes a controll er configured to detect indicia of incipient mechanical motor faults. The co ntroller further includes a processor programmed to receive a baseline set o f current data from an operating motor and define a noise component in the b aseline set of current data. The processor is also programmed to repeatedly receive real-time operating current data from the operating motor and remove the noise component from the operating current data in real-time to isolate any fault components present in the operating current data. The processor i s then programmed to generate a fault index for the operating current data b ased on any isolated fault components.
