Zusammenfassung:In this paper, the magnetic material characteristics are reconstructed for magnetic circuits with non-uniform electromagnetic field patterns, including excitation winding and/or air gaps, as in the case of rotating electrical machines. The identification process is done using a set of well chosen global and/or local magnetic measurements. Moreover, numerical inverse techniques are implemented in order to reconstruct the material characteristics from a limited number of global and/or local measurements.
