Information
This information is part of the Modelica Standard Library maintained by the Modelica Association.
Test example: Steady-State Initialization of Asynchronous induction machine with squirrel cageThe 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
