Abstract: The present invention is directed to system and method for determining motor wellness based on potential faults including cavitation faults. Specifically, a controller configured to detect indicia of motor faults. The controller includes a processor configured to determine motor parameters of a given motor, generate a set of baseline data for the given motor, and acquire current data from the given motor during operation. The processor is also caused to isolate sidebands within the current data and map the current data within the sidebands to one of a plurality of bins. The processor is caused to compare the current data within the sidebands to baseline data from the set of baseline data associated with the bin and determine a predictive fault index of the given motor prior to an actual fault occurrence.
