Abstract
Methods and apparatuses for detecting faults and optimizing phase currents in an electromechanical energy converter are disclosed. An example method comprises: measuring a current of a phase of the electromechanical energy converter, modeling the electromechanical energy converter with the current measurement input into a field reconstruction module, calculating a flux linkage of the electromechanical energy converter, comparing the flux linkage with a flux linkage from a no fault electromechanical energy converter, and optimizing the current of the phase of the electromechanical energy converter in response to the comparison. Other embodiments are described and claimed.
