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 accelerate the inertias.

At time tStep a load step is applied. Simulate for 1.5 seconds and plot (versus time):

  • currentRMSsensorM|E.I: equivalent RMS stator current
  • smpmM|E.wMechanical: machine speed
  • smpmM|E.tauElectrical: machine torque
  • rotorAnglepmsmM|E.rotorDisplacementAngle: rotor displacement angle
