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):
