modelIMC_Initialize
Steady-state initialization of induction machine with squirrel cage
Extends from Modelica.Icons.Example (Icon for runnable examples).
Information
The 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.
