IMC_InitializeTest example: Steady-State Initialization of InductionMachineSquirrelCage |
SystemModel["Modelica.Electrical.Machines.Examples.InductionMachines.IMC_Initialize"]
This information is part of the Modelica Standard Library maintained by the Modelica Association.
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):
Default machine parameters are used.
