Modelling of a permanent magnet electrical machine with stator core anisotropy
Languages of publication
This article deals with the methodological aspects of the modelling and field analysis of machines with surface mounted permanent magnets on the rotor, taking into account the anisotropic properties of the stator core. These considerations are intended to show the effect of anisotropy on the structure of the mathematical model of the machine and answer the question of whether if based on classical modelling, it is possible to take into account the rotational magnetization phenomena. The results explain the question, how the magnetic anisotropy effect at rotational magnetization is important from an exploitation point of view.
