This is a simple model of a rotational eddy current brake. The torque versus speed characteristic is defined by Kloss' equation.

Thermal behaviour:
The resistance of the braking disc is influenced by the actual temperature Theatport, which in turn shifts the speed w_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 w_nominal at which the maximum torque occurs is adapted from reference temperature TRef to the operational temperature.

useSupport	Value: false Type: Boolean Description: = true, if support flange enabled, otherwise implicitly grounded
useHeatPort	Value: false Type: Boolean Description: =true, if heatPort is enabled
T	Value: 293.15 Type: Temperature (K) Description: Fixed device temperature if useHeatPort = false
tau_nominal	Value: Type: Torque (N·m) Description: Maximum torque (always braking)
w_nominal	Value: Type: AngularVelocity (rad/s) Description: Nominal speed (leads to maximum torque) at reference temperature
TRef	Value: Type: Temperature (K) Description: Reference temperature
alpha20	Value: Type: LinearTemperatureCoefficient20 (¹/K) Description: Temperature coefficient of material
