This example investigates a time transient polyphase induction machine.
An ideal frequency inverter is modeled by using a simple
voltage frequency controller
and a polyphase voltage source with signal input.
Frequency is raised by a ramp up to nominal frequency, causing the induction machine with squirrel cage to start,
and accelerating inertias. At time tStep
a load step is applied.
