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 are fed by a current source. The current components are oriented at the magnetic field orientation and transformed to the stator fixed reference frame. This way the machines are operated at constant torque. The machines start to accelerate from standstill.

Simulate for 2 seconds and plot (versus time):

  • smpm|smpmQS.wMechanical: machine speed
  • smpm|smpmQS.tauElectrical: machine torque
Note

The resistors connected to the terminals of the windings of the quasi static machine model are necessary to numerically stabilize the simulation.
