This information is part of the Modelica Standard Library maintained by the Modelica Association.
This examples allows the investigation of characteristic curves of quasi-static polyphase induction machines with slip ring rotor as a function of rotor speed.
Simulate for 1 second and plot (versus imsQS.wMechanical or perUnitSpeed):
