Information

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

The asynchronous induction machine with squirrel cage is initialized in steady-state at no-load; at time tStart a load torque step is applied.

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.
