Information
This information is part of the Modelica Standard Library maintained by the Modelica Association.
This example compares a time transient and a quasi static model of a permanent magnet synchronous machine. The machines start with zero load and synchronous speed. At time tStep the machines are loaded with nominal torque.
Simulate for 1 second and plot (versus time):
