Mains operated permanent magnet synchronous machine loaded with step torque

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):

  • currentRMSsensor.I|currentSensorQS.abs_i[1]: (equivalent) RMS stator current
  • smpm|smpmQS.wMechanical: machine speed
  • smpm|smpmQS.tauElectrical: machine torque
