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