An ideal frequency inverter is modeled by using VfControllers and SignalVoltagess. Frequency is raised by a ramp, causing the permanent magnet synchronous machines to start, and accelerate the inertias. Two equivalent machines with different numbers of phases are compared and their equal behavior is demonstrated.
At time tStep a load step is applied. Simulate for 1.5 seconds and plot (versus time):
