Information

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

Test example: Electrically separate excited DC machine started with an armature voltage ramp
A voltage ramp is applied to the armature, causing the DC machine to start, and accelerating inertias.
At time tStep a load step is applied.
Simulate for 2 seconds and plot (versus time):
  • dcee.ia: armature current
  • dcee.wMechanical: motor's speed
  • dcee.tauElectrical: motor's torque
  • dcee.ie: excitation current
Default machine parameters of model DC_ElectricalExcited are used.
