Characteristic curves of induction machine with slip rings
Extends from Modelica.Icons.Example (Icon for runnable examples).
Information
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 speedPerUnit):
iSensorQS.I: (equivalent) RMS stator currentimsQS.tauElectrical: machine torqueimsQS.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
