Information

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

Base partial model DC machines:
  • main parts of the icon
  • mechanical shaft
  • mechanical support
Besides the mechanical connector flange (i.e., the shaft) the machines have a second mechanical connector support.
If useSupport = false, it is assumed that the stator is fixed.
Otherwise reaction torque (i.e., air gap torque, minus acceleration torque for stator's moment of inertia) can be measured at support.
One may also fix the shaft and let rotate the stator; parameter Js is only of importance when the stator is rotating.
