Within the Clean Sky project MoMoLib (Modelica Model Library Development for Media; Magnetic Systems and Wavelets) an extension for the Modelica.Magnetic.FluxTubes library has been developed. This extension mainly consists of new flux tubes elements for the consideration of the magnetic hysteresis in the transient simulation of electromagnetic networks; a materials library with hysteresis data of various magnetic materials and a new components package with models of one- and three-phase transformers; which also account for the magnetic hysteresis of the core. This paper briefly presents the implemented hysteresis models for the simulation of the static (ferromagnetic) and dynamic (eddy currents) hysteresis. It shows the accurate computation of the instantaneous hysteresis losses; which be-comes increasingly important for the design of electromagnetic components with increasing requirements regarding energy efficiency and mass power densities. Furthermore; the new components of the library extension are introduced and the behavior of the implemented elements is verified and compared to measurements and steel sheet datasheets.
