An anisotropic vector hysteresis model of ferromagnetic behavior under alternating and rotational magnetic field

Vector quantities and tensorial properties rule the magnetization mechanisms in ferromagnetic materials. Every material is anisotropic to some degree its magnetic response, so this anisotropy has be considered for a general model. In study, multiscale approach based on statistical description of domain distribution knowledge crystallographic texture used predict anhysteretic behavior along an arbitrary space direction. Combined with vector Bergqvist dry-friction hysteresis model, qualitatively reliable simulation results are obtained under alternating rotational magnetization. FeSi 3% grain-oriented (FeSi GO) electrical steel chosen as study material: GO widespread that extensive data available strongly anisotropic, forcing model toward “worst-case” scenario from viewpoint anisotropy. Moreover, high excitation magnetization, losses drop due disappearance domains. This represented correctly by proposed method. such conditions, led mainly behavior, strengthening predictive ability manuscript, comparisons between simulations measurements many amplitudes different levels imposed or provided validate
