Anomaly detection for rotating machines

A system comprising:

• at least one processor;
• and
• at least one memory storing computer-executable instructions, that when executed by the at least one processor, cause the at least one processor to:
• determine a rotational speed of a rotating machine;
• determine, using a frequency domain transform of a signal of the rotating machine, a frequency domain signal;
• determine, based on a predetermined frequency distance from the rotational speed of the rotating machine, a first frequency band within the frequency domain signal for identifying a fault frequency of the rotating machine;
• determine a fault frequency of the rotational machine within the first frequency band;
• determine, based on the fault frequency, a second frequency band within the first frequency band, wherein the second frequency band includes the fault frequency;
• determine, based on the second frequency band, a first fault index indicative of a failure mode, and a baseline of the first fault index for detecting a fault condition;
• determine, based on a deviation from the baseline, the fault condition of the rotating machine;
• and
• provide an alert based on the fault condition of the rotating machine.
