Information
This information is part of the Modelica Standard Library maintained by the Modelica Association.
This is a simple model of a translational eddy current brake. The force versus speed characteristic is defined by Kloss' equation.
Thermal behaviour:
The resistance of the braking fin is influenced by the actual temperature Theatport, which in turn shifts the speed v_nominal at which the (unchanged) maximum torque occurs.
If the heatPort is not used (useHeatPort = false), the operational temperature remains at the given temperature T.
However, the speed v_nominal at which the maximum torque occurs is adapted from reference temperature TRef to the operational temperature.
