A Phenomenological Model to Account Anisotropic Magnetic Properties of Electrical Steels

Anisotropy is an intrinsic and persistent feature of crystalline materials. The paper considers its effect on the magnetic properties of electrical steels (non-oriented and grain-oriented). In particular the angular dependence of coercive field strength is discussed. A simple phenomenological model derived from texture analysis in materials science is adapted for the aforementioned dependence. The paper proves that the approach offers a straightforward way to describe the angular dependence of important quantities used for the characterization of electrical steels, thus it might be interesting and useful to the designers of magnetic circuits in electrical machines.
