Abstract:
A system includes a proportional-integrated-derivative (PID) regulator. The system also includes a fault detection unit. The fault detection unit is for receiving at least two outputs from the PID regulator. The at least two outputs include at least two rotor reference frame (D-Q) currents. The fault detection unit is further for generating a detection signal based on the at least two rotor reference frame currents. The detection signal identifies a fault based on the fault detection signal amplitude value based on the magnitudes of the amplitudes for each of the at least two rotor reference frame D-Q currents. The fault detection unit is for identifying an existence of a permanent magnet motor fault based on a comparison between the fault detection signal amplitude value and an amplitude threshold value. Further the fault localization signature is utilized to locate the location of the fault.

Claim (Index 9):
A fault detection circuit comprising:\n a threshold detector circuit coupled to receive at least first and second rotor reference frame currents from a regulator circuit and determine magnitudes of amplitudes for the first and second rotor reference frame currents; a signal detector configured to generate a detection signal based on the first and second rotor reference frame currents; and a comparator configured to compare the detection signal with an amplitude threshold value to identify an existence of a permanent magnet motor fault; wherein the first rotor reference frame current is a D-axis current, and the second rotor reference frame current is a Q-axis current, and wherein the detection signal is equal to a magnitude of the D-axis current divided by a sum of magnitudes of the D-axis current and the Q-axis current.
