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 multi phase 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 current
  • imsQS.tauElectrical: machine torque
  • imscQS.powerBalance.powerStator: stator power
  • imsQS.powerBalance.powerMechanical: mechanical power

Default machine parameters are used. The rotor resistance may be varied to demonstrate the impact on the characteristic curves
