Information
This information is part of the Modelica Standard Library maintained by the Modelica Association.
Flux tube element for modeling magnetic materials with ferromagnetic and dynamic hysteresis (eddy currents). The ferromagnetic hysteresis behavior is defined by the Preisach hysteresis model. The Shape of the limiting ferromagnetic hysteresis loop is specified by an analytical description of the Everett function. A library of predefined parameter sets can be found in FluxTubes.Material.HysteresisEverettParameter.
An overview over all available hysteresis and permanent magnet elements of the package HysteresisAndMagnets can be found in UsersGuide.Hysteresis.
