IMC_Characteristics

Characteristic curves of Induction machine with squirrel cage

Diagram

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 squirrel cage rotor as a function of rotor speed.

Simulate for 1 second and plot (versus imcQS.wMechanical or perUnitSpeed):

  • currentSensorQS.abs_i[1]: (equivalent) RMS stator current
  • imcQS.tauElectrical: machine torque
  • imcQS.powerBalance.powerStator: stator power
  • imcQS.powerBalance.powerMechanical: mechanical power
