modelIMC_Transformer
Test example: InductionMachineSquirrelCage transformer starting
Extends from Machines.Examples.InductionMachines.IMC_Transformer (Test example: InductionMachineSquirrelCage transformer starting).
Information
Test example: Induction machine with squirrel cage - transformer startingAt start time tStart1 three-phase voltage is supplied to the induction machine with squirrel cage via the transformer; the machine starts from standstill, accelerating inertias against load torque quadratic dependent on speed; at start time tStart2 the machine is fed directly from the voltage source, finally reaching nominal speed.
Simulate for 2.5 seconds and plot (versus time):
- currentQuasiRMSSensor.I: stator current RMS
- aimc.wMechanical: motor's speed
- aimc.tauElectrical: motor's torque
