The present invention is directed to a system and method for proactively
determining motor wellness arising from potential mechanical faults of
the motor. A controller is configured to detect indicia of impending
mechanical motor faults. The controller includes a processor configured
to determine motor parameters of a given motor including a load and
generate a set of baseline data for the given motor. The processor is
also configured to acquire current spectrum data from the given motor
during operation, map at least one from a plurality of load bins based on
the load, and generate a mechanical fault signature from the current
spectrum. The processor is caused to compare the mechanical fault
signature to baseline data from the set of baseline data corresponding to
the mapped bin and determine amplitude variances within the mechanical
fault signature indicative of an impending mechanical fault prior to an
actual mechanical fault occurrence.
