This work deals with the magnetically nonlinear two-axis dynamic model of a permanent-magnet synchronous motor with exterior rotor (PMSM). The model is written in the d-q reference frame, where the d-axis is aligned with the magnetic axis of permanent magnets. Magnetically nonlinear behavior of the PMSM iron core is accounted for by current- and position-dependent characteristics of flux linkages. This work focuses on experimental methods used for determining aforementioned characteristics of flux linkages. These characteristics are composed of two parts. The first part contains effects due to the permanent magnets at no armature excitation. It is determined from the induced voltages measured on the open motor terminals while the motor shaft is rotated with speed controlled load at constant angular speed. The second part of flux linkage characteristics contains effects due to the armature excitation. It is determined by tests performed on locked rotor. The SMPM is supplied by a controlled voltage source inverter. Current in one axis is closed loop controlled in order to keep constant value, while voltage in the orthogonal axis is changing in the stepwise manner. For the given position and constant value of controlled current in one axis, the flux linkage characteristic in the orthogonal axis is determined by numerical integration using measured applied voltage and responding current. In this way determined characteristics of flux linkages contain effects of saturation, cross-saturation and effects of slotting.

Artykuł przedstawia analizę dwuosiowego dynamicznego modelu silnika synchronicznego z magnesami trwałymi, uwzględniającego nieliniowość magnetyczną (PMSM). Model jest opisany we współrzędnych d-q, gdzie współrzędna d jest związana z osią magnetyczną magnesu. Badania skoncentrowane są na metodach eksperymentalnych do określenia charakterystyk strumienia magnetycznego.
