Computation of temperature fields in ferromagnetics

The analysis of electromagnetic processes in laminated cores can be simplified on taking into consideration equivalent solid medium with anisotropic properties. Such medium can be defined on the basis homogenous isotropic pieces of the real core structures. We shown that electromagnetic characteristics of the isotropic structure are similar as in real laminated structure, but the temperature losses generated by eddy currents are different. The analysis of realized computations show that this difference irtcreases taking in account temperature fields. The computation are realized on integration of quasi-stationary electromagnetic and not stationary temperature fields in laminated and solid cores of toroidal choke.
