Information
This information is part of the Modelica Standard Library maintained by the Modelica Association.
The stator windings of an induction machine are fed by a DC current, causing a stationary current space phasor. Since the rotor is turning, voltage is induced in the rotor cage which in turn drives rotor currents. This creates a braking torque.
Choose a layout and plot tauElectrical and tauShaft versus wMechanical.
Default machine parameters are used.
