Abstract

A system for monitoring a motor includes a movable component having a plurality of permanent magnets. The system also includes a plurality of stators having phase windings and surrounding the movable component. The system also includes a plurality of current sensors each configured to detect a detected current flowing to a corresponding stator of the plurality of stators. The system also includes a monitor configured to receive the detected current, perform a comparison of the detected current from each of the plurality of stators, and to identify a loss of redundancy of the motor based on the comparison.
