“…When the vertex of the applied magnetic field vector is outside the critical curve, the magnetization is perpendicular to the relative line with and it is directed along the relative line with . In this case the magnetization processes are congruent with the coherent rotation described by the Stoner-Wohlfarth model, and for this reason we have called "physical-related" the phenomenological model presented in this paper [13]. The magnetization components and , for a given applied magnetic field , are computed by means of a numeric solution of the equation (5) obtained by a suitable manipulation of the (4).…”

In this work we present a physical-related model of vector hysteresis for magnetic simulation of nanometric structures. The mathematical formulation, based on a generalization of the Preisach and Stoner-Wohlfarth models, is very simple and elegant. The numerical implementation is very easy and the computation time required for the simulations is extremely fast. However the accuracy is not comparable with the codes based on the micromagnetic theory, but it is sufficient for the use as preprocessing of more accurate and more complex methods, in order to speed up the convergence. In this paper the model identification is performed for a nanoscale spin valve using the data generated by a 3D micromagnetic code.

“…The stator windings have been connected to a 20 Ω resistive load. In order to assess the effects of the stator structure on the overall performance of the machine, we evaluated the flux linkage with the windings, the induced voltages, the currents, the force along the moving direction and the total iron losses (as the sum of eddy current losses, losses due to magnetic hysteresis and additional losses) [14,15].…”

Abstract-In this paper the authors perform a comparison among three different stator structures for a Tubular Permanent Magnet Linear Machine. Each structure is characterized by its own lamination which is expected to contribute to the overall performance of the machine. A detailed analysis of the main figures of merit of the three configurations has been carried out in order to identify the configuration with the best characteristics. Significant data such as flux distribution, rated voltage and current, force on the moved and power losses have been compared. The results show that the choice of a mixed stator lamination allows to improve the performance of these machines.

“…In general the magnetic hysteresis is a complex phenomena that needs several sophisticated models for different cases and applications [3][4][5][6][7][8][9]. Recently some vector models have been proposed and discussed for the electrical steels representation [10][11][12], one of them is the Vector Hysteron Model (VHM) [13] which is a natural extension of the Preisach theory to the vector case. In this work we present the VHM formulation in order to model experimental hysteresis loops, scalar and rotational, for both NOG (Not oriented grain) and OG (Oriented grain) steels.…”

The paper deals with the modeling of the magnetic materials used for electrical machines. The model proposed is able to simulate the magnetization processes of the NOG and OG steels which are usually used in the magnetic core of electrical motors, generators and transformers. For the validation of the model we present some experiments about the prediction of transformer inrush currents, in particular the simulation results are compared with the measurements.
