Test example: Permanent magnet synchronous induction machine fed by an ideal inverter
An ideal frequency inverter is modeled by using a VfController and a three-phase SignalVoltage.
Frequency is raised by a ramp, causing the permanent magnet synchronous induction machine to start, and accelerating inertias.
At time tStep a load step is applied.
Simulate for 1.5 seconds and plot (versus time):
  • currentQuasiRMSSensor.I: stator current RMS
  • smpm.wMechanical: motor's speed
  • smpm.tauElectrical: motor's torque
  • rotorDisplacementAngle.rotorDisplacementAngle: rotor displacement angle
Default machine parameters of model SM_PermanentMagnet are used.

In practice it is nearly impossible to drive a PMSMD without current controller.
