Information

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

Test example: Synchronous machine with reluctance rotor direct on line
A synchronous machine with reluctance rotor starts direct on line, utilizing the damper cage.
After reaching synchronous speed, at time tStep a load step is applied.
Simulate for 2.5 seconds and plot (versus time):

currentQuasiRMSSensor.I: stator current RMS
smr.wMechanical: motor's speed
smr.tauElectrical: motor's torque
rotorDisplacementAngle.rotorDisplacementAngle: rotor displacement angle

Default machine parameters of model SM_ReluctanceRotor are used.
