“…This section covers a short mathematical overview of the tested models and their respective parameters. A profound description can be found in (Kaltenbacher, 2015;Mayergoyz, 2003;Rupitsch, 2019;Sutor et al, 2012;Sutor et al, 2015) and shall not be repeated in detail here.…”

“…Furthermore, the Preisach weights for the particular scalar models require additional derivation, even for isotropic materials (Bottauscio et al, 1998). Sutor et al (2012) and Sutor et al (2015) proposed two vector Preisach models (VPR), which are based on a supplementary rotational operator that is added to SP. This lightweight extension of SP is suitable for isotropic materials and has the advantage that the Preisach weights of SP can be reused without further computations.…”

Purpose The numerical computation of magnetization processes in moving and rotating assemblies requires the usage of vector hysteresis models. A commonly used model is the so-called Mayergoyz vector Preisach model, which applies the scalar Preisach model into multiple angles of the halfspace. The usage of several scalar models, which are optionally weighted differently, enables the description of isotropic as well as anisotropic materials. The flexibility is achieved, however, at the cost of multiple scalar model evaluations. For solely isotropic materials, two vector Preisach models, based on an extra rotational operator, might offer a lightweight alternative in terms of evaluation cost. The study aims at comparing the three mentioned models with respect to computational efficiency and practical applicability. Design/methodology/approach The three mentioned vector Preisach models are compared with respect to their computational costs and their representation of magnetic polarization curves measured by a vector vibrating sample magnetometer. Findings The results prove the applicability of all three models to practical scenarios and show the higher efficiency of the vector models based on rotational operators in terms of computational time. Originality/value Although the two vector Preisach models, based on an extra rotational operator, have been proposed in 2012 and 2015, their practical application and inversion has not been tested yet. This paper not only shows the usability of these particular vector Preisach models but also proves the efficiency of a special stageless evaluation approach that was proposed in a former contribution.

“…Less important are the so called Néel walls, which on the other hand are crucial for thin films and ribbons that can be approximated by two-dimensional domain structure model such as the Van den Berg construction [4]. Distribution of magnetic moments in thin cores was simulated in [5] and [6]. For both domain wall types external magnetic field vector and domain magnetization vector are on the same rotation plane.…”

In this paper possibility of application two-dimensional vector Preisach model for bulk materials was investigated. Physical magnetization mechanisms in bulk cores and thin ribbons were analyzed. Model is based on collection of the Preisach planes which describe material state in different angles on rotation plane. Presented model exhibits good conformity with experimental data for bulk as well for ribbon shaped cores. Model includes anisotropy and describes not only mean magnetization vector, but also distribution of magnetic moments for different angles.
