Information
This information is part of the Modelica Standard Library maintained by the Modelica Association.
At start time tStart three phase voltage is supplied to the asynchronous induction machine with squirrel cage; the machine starts from standstill, accelerating inertias against load torque quadratic dependent on speed, finally reaching nominal speed.
Simulate for 1.5 seconds and plot (versus time):
- currentQuasiRMSSensor.I: stator current RMS
- aimc.wMechanical: motor's speed
- aimc.tauElectrical: motor's torque
Default machine parameters are used.
