Information

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

Model of an asymmetrical damper cage in two axis.

The damper cage has an optional (conditional) HeatPort, which can be enabled or disabled by the Boolean parameter useHeatPort. Temperatures of both axis are the same, both losses are added. Material properties alpha can be set differently for both d- and q-axis, although reference temperature for both resistances is the same.
