GenericHystTellinenTable

Generic flux tube with ferromagnetic hysteresis based on the Tellinen model and table data

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 Tellinen hysteresis model. The rising and falling branch of the limiting ferromagnetic hysteresis loop are specified by table data. Therefore, almost any hysteresis shapes are possible. A library with predefined tables can be found at FluxTubes.Material.HysteresisTableData.

An overview of all available hysteresis and permanent magnet elements of the package HysteresisAndMagnets can be found in UsersGuide.Hysteresis.
