Squirrel Cage
Extends from Modelica.Electrical.Analog.Interfaces.ConditionalHeatPort (Partial model to include a conditional HeatPort in order to describe the power loss via a thermal network).
Information
Model of a squirrel cage / symmetrical damper cage in two axis.
The squirrel 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 of both axis are the same.
Parameters
