Model of Magnetic Anisotropy of Non-Oriented Steel Sheets for Finite-Element Method

Abstract: Even non-oriented steel sheets present a magnetic anisotropic behavior. From rotational flux density measurements at 5 Hz, the model of magnetic anisotropy is derived from two surface Basis-cubic splines with the boundary conditions matching with ferromagnetic theory. Furthermore, the investigation of the magnetic anisotropy shows that the H(B) characteristic is not strictly monotonous due to the angle difference between the field and the flux density. Hence, standard non-linear solvers would either diverge or… Show more

“…The unidirectional alternating magnetic field measurements are shown in Figures 2 and 3, and Figure 6 depicts the rotational measurements. Thus, the silicon steel sample of grade M400-50A reveals weak magnetic anisotropy (Figure 6) as compared to the measurement done on an NO electrical steel sample at 5 Hz by Martin et al (2016).…”

“…However, the results they predict disagree with the measurement data. Instead of using the magnetic energy, [11] employs bicubic splines to represent the anhysteretic characteristics identified from the rotational measurements. The method based on the surface bicubic spline is easier to integrate with the FEM and it is more accurate than the energy-density method.…”

“…There is an important implicit assumption in the scalar permeability models that the magnetic flux density B always parallels with the applied field H, which is only a valid approximation at low and uniform fields. Some tensor permeability models [13][14][15][16] have been reported to be able to address this limitation, which also facilitates finite element modelling [17][18][19] to solve problems that involve rotational fields and complex geometry. Nevertheless, tensor models require prior knowledge of the permeability for principal directions, along which B parallels with H, to formulate a permeability tensor.…”
