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):
