Modelica_Magnetic

Information

This library contains components for modelling of electromagnetic devices with lumped magnetic networks. Those models are suited for both rough design of the magnetic subsystem of a device as well as for efficient dynamic simulation at system level together with neighbouring subsystems. At present, components and examples for modelling of translatory electromagnetic and electrodynamic actuators are provided. If needed, these components can be adapted to network modellling of rotational electrical machines.

Users Guide gives a short introduction to the underlying concept of magnetic flux tubes, summarizes the calculation of magnetic reluctance forces from lumped magnetic network models and lists reference literature.

Examples illustrates the usage of magnetic network models with simple models from different fields of application.
