Information

This information is part of the Modelica Standard Library maintained by the Modelica Association.

Test example: Asynchronous induction machine with slipring rotor - resistance starting
At start time tStart1 three phase voltage is supplied to the asynchronous induction machine with sliprings; the machine starts from standstill, accelerating inertias against load torque quadratic dependent on speed, using a starting resistance. At time tStart2 external rotor resistance is shortened, finally reaching nominal speed.
Simulate for 1.5 seconds and plot (versus time):
  • currentQuasiRMSSensor.I: stator current RMS
  • aims.wMechanical: motor's speed
  • aims.tauElectrical: motor's torque
Default machine parameters of model AIM_SlipRing are used.
