Synchronous induction machine with reluctance rotor 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 reluctance machine to start, and accelerating 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
  • smrM|E.wMechanical: machine speed
  • smrM|E.tauElectrical: machine torque
  • rotorAngleM|R.rotorDisplacementAngle: rotor displacement angle
