Information
This information is part of the Modelica Standard Library maintained by the Modelica Association.
This examples allows the investigation of characteristic curves of quasi-static polyphase induction machines with slip ring rotor as a function of rotor speed.
Simulate for 1 second and plot (versus imsQS.wMechanical or perUnitSpeed):
currentSensorQS.abs_i[1]: (equivalent) RMS stator currentimsQS.tauElectrical: machine torqueimscQS.powerBalance.powerStator: stator powerimsQS.powerBalance.powerMechanical: mechanical power
Default machine parameters are used. The rotor resistance may be varied to demonstrate the impact on the characteristic curves
