Abstract:
A controller for driving a motor includes a multiphase driver, an analog-to-digital converter (ADC), impedance estimation circuitry, and fault detection circuitry. The multiphase driver is configured to generate drive signals for energizing each motor phase winding. The ADC is configured to digitize voltage and current from each motor phase winding. The impedance estimation circuitry is configured to determine a phasor value for the digitized voltages and for the digitized currents at a predetermined harmonic frequency, and to determine a sequence impedance value based on the phasor values. The fault detection circuitry is configured to identify a fault in the windings of the motor based on the sequence impedance value.

Claim (Index 7):
The system of  claim 3 , wherein the ADC is configured to provide a digitizing frequency that is a difference of the predetermined inverter harmonic frequency and a predetermined frequency that is less than the digitizing frequency of the ADC.
