The magnetic flux includes dc component and ac component in the square laminated core (SLC) under dc-biased magnetization. Hysteresis loops are distorted by dc component of magnetic field intensity in ferromagnetic core and exhibit asymmetrical and special nonlinearities. A neural network (NN) is trained on the basis of the experimental data to model hysteresis effects in the limb-yoke of the SLC...
The harmonic balance finite element method (HBFEM) is combined with the fixed-point technique to calculate the steady-state magnetic field in a laminated core model (LCM). The magnetic intensity is divided into linear and nonlinear parts in the form of harmonics. The hysteresis model based on the consuming function is taken into account in the harmonic computation. The magnetic field and magnetizing...
