Information

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

Test example: Permanent magnet 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):
  • dcpm.ia: armature current
  • dcpm.wMechanical: motor's speed
  • dcpm.tauElectrical: motor's torque
Default machine parameters of model DC_PermanentMagnet are used.
