“…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.

“…Several models and approaches have been presented in literature regarding the study of magnetic hysteresis phenomena [1][2][3][4][5][6][7][8][9][10][11][12]. Nevertheless, the Jiles-Atherton (JA) model has been widely used in both literature and industry applications for many years.…”

An improvement of the Jiles-Atherton model by introducing a dynamic dependence of all five parameters is presented. The values of parameters dynamically change as a function of the magnetic field excitation. The proposed model aims to improve the poor performance of the classic model Jiles-Atherton in generalizing both saturated and minor loops of a given material. Non-linear optimization techniques such as Genetic Algorithm (GA), Trust-Region-Reflective (TRR) and Levenberg-Marquardt (LM) were used by a hybrid configuration for the parameter identification, using hysteresis loops generated with the Preisach model as target. Different cases of excitation trends are investigated and final validation and comparison results are presented

“…Micromagnetic and phenomenological models can be used for the constitutive equations [1], [2]. Recently, based on a generalization of the Preisach and Stoner-Wohlfarth models, a physical-related vector hysteresis model has been used to reproduce the results of micromagnetic computations for nanomagnets [3]- [5]. We have called the model "physical-related" because, although it is essentially phenomenological, some features of the model, such as the introduction of an interaction field and the shape of the hysteresis operator are in some sense related to the micromagnetic theory, such as the exchange field and the Stoner-Wohlfarth model for a magnetic particle with single anisotropy.…”

“…Differently from our previous works, here we study the magneto-resistive hysteresis loop of a spin valve composed by two nanomagnets (one of them exchange biased), separated by a normal metal spacer coupled by the means of the magnetostatic interaction. We compare the numerical results obtained using 3D micromagnetic computations [6] and the physical-related vector model [3]. The micromagnetic model allows to perform a systematic study of the spin valve with high accuracy.…”

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.
