Information

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

Test example: Steady-State Initialization of an induction machine with squirrel cage
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 of model IM_SquirrelCage are used.
