IMC_DCBraking

Induction machine with DC current braking

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.
