Induction machine with squirrel cage fed by an ideal inverter
This example compares a time transient and a quasi static model of a multi phase induction machine.
An ideal frequency inverter is modeled by using a
Simulate for 1.5 seconds and plot (versus time):VfController and a multi phase SignalVoltage.
Frequency is raised by a ramp, causing the induction machine with squirrel cage to start,
and accelerating inertias. At time tStep a load step is applied.
