Information

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 speedPerUnit):

  • iSensorQS.I: (equivalent) RMS stator current
  • imcQS.tauElectrical: machine torque
  • imcQS.powerBalance.powerStator: stator power
  • imcQS.powerBalance.powerMechanical: mechanical power
