modelDCPM_Start
Test example: DC with permanent magnet starting with voltage ramp
Extends from Modelica.Icons.Example (Icon for runnable examples).
Information
Test example: Permanent magnet 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):
- dcpm.ia: armature current
- dcpm.wMechanical: motor's speed
- dcpm.tauElectrical: motor's torque
