“…The vector magnetic properties of material and the tensor expression of the reluctivity in the The vector magnetic properties are defined by three parameters including the maximum flux density, orientation and axis ratio of the elliptical B locus [16,17]. The orientation is defined by the direction of major axis of the B ellipse, which is given by the angles between the major axis and the three coordinate axes [18,19].…”

Soft magnetic composite (SMC) materials are especially suitable for construction of electrical machines with complex structures and three-dimensional (3-D) magnetic fluxes. In the design and optimization of such 3-D flux machines, the 3-D vector magnetic properties of magnetic materials should be properly determined, modeled and applied for accurate calculation of the magnetic field distribution, parameters and performance. This paper presents the measurement of 3-D vector magnetic properties and determination of 3-D reluctivity tensor of SMC. The reluctivity tensor is a key factor for accurate numerical analysis of magnetic field in a 3-D flux SMC motor.

“…It became possible to be detected by two-dimensional magnetic vector property method (2D-MAG), where magnetic flux density and magnetic field are treated to be a vector in two dimensional plane. However it is not easy to get a parameter of Enokizono, Soda and Shimoji (E&SS) model, a kind of FEM on magnetic static field [5][6][7], from an experimental data and they did not mention the cause of the � BH . Moreover inputted measured data contain many magnetic characteristics such as magnetic anisotropy, magnetic hysteresis, � BH , etc.…”

The cause of angle difference between B vector and H vector (� BH ) is made clear by means of numerical calculation taking into account of the magnetic hysteresis and magnetic anisotropy. Since the � BH , which is measured by the 2D magnetic vector property method, is usually ignored in the numerical calculation of electromagnetic field, it is our necessary to consider its effect on the numerical calculation. The research work says the � BH is possible to be expressed by the magnetic hysteresis phenomenon and the magnetic anisotropic phenomenon in numerical calculation of magnetic field. Therefore, the development to create the � BH model is not always necessary.

“…There have been researches, therefore, to develop a permeability (or reluctivity) model to express 2-D magnetic properties of grain-oriented silicon steel [1]- [3]. Especially, Enokizono proposed several models [4]- [6], such as, using direct description of the relationship between (magnetic flux density) and (magnetic field intensity), and obtaining the magnetic reluctivity parameters by using Fourier series expansion of the measured -waveforms.…”

This paper presents an improved magnetic reluctivity model for vector magnetic properties of anisotropic electrical steel sheet based on Chua-type model using Fourier series expansion of measured B and H waveforms in the viewpoint of engineering application. In the modeling, B-spline surface interpolation is adopted to obtain smooth approximation of measured data. The accuracy of the proposed magnetic reluctivity model is verified by comparing its modeling results with experimentally measured B-and H-waveforms with 30PG110 grain-oriented silicon steel sheet. The nonlinear finite element (FE) formulation is also derived to incorporate the proposed reluctivity model, and applied to magnetic field analysis of a single phase transformer core model. By comparing the numerical results with experimental ones, the effectiveness of the reluctivity model and FE formulation is investigated.Index Terms-Finite element analysis, Fourier series expansion, grain-oriented silicon steel sheet, magnetic reluctivity model.
