Abstract: A self-commissioning method for estimating differential inductances in an electric machine, such as e.g. a synchronous reluctance machine or interior permanent magnet machine, with cross-magnetization effects is provided. The electric machine is driven with PWM voltages to explore current plurality of operating points of the currents in the electric machine while keeping the electric machine at standstill or quasi-standstill. At each operating point PWM switching voltage transients are used as a small-signal excitation. Currents of the electric machine are measured by means of oversampling, which permit the reconstruction of the waveforms including the current ripple within a PWM period caused by the PWM switching transients. Finally, the differential inductances at each operating point are determined based on the determined direct and quadrature current waveforms and voltages.
