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):
