Modelling of permanent magnet AC machine by taking into account dynamic and static inductances

As it is well known, PM AC machines are more and more used in a wide range of applications, especially in the field of servo-drives systems. In the paper, the traditional lumped parameters model of the PMAC machine is reviewed and the dynamic and static armature inductances are introduced in order to take into account saturation phenomena of the main flux path. Experimental comparisons with the traditional model are performed.
