modelSMPM_Mains
Permanent magnet synchronous machine operated at mains with step torque load
Extends from Modelica.Icons.Example (Icon for runnable examples).
Information
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):
