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 rampA 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
