Information

This information is part of the Modelica Standard Library maintained by the Modelica Association.

Flux tube element for modeling the ferromagnetic (static) hysteresis of hard magnetic materials. The ferromagnetic hysteresis behavior is defined by the Tellinen hysteresis model. The shape of the limiting hysteresis loop is described by simple hyperbolic tangent functions with 4 parameters.

Fig. 1: Hyperbolic tangent functions define the shape of the ferromagnetic (static) hysteresis

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