During the development of advanced models of mechatronics devices with cores made of anisotropic soft magnetic materials, magnetic permeability has to be described as tensor. However commonly used tensor magnetic permeability descriptions doesn’t consider saturation phenomenon for flux density. As a result accuracy of such simulations is significantly limited, especially for higher values of magnetizing field. Paper is proposing new method of magnetic permeability description considering saturation flux density. Proposed concept is based on the anisotropy energy analyze and was verified for magnetization curve of soft magnetic materials with uniaxial anisotropy. Results of modeling confirm good agreement with the results experimental measurements for soft magnetic materials with uniaxial anisotropy.
