Information
Description
This example investigates a transient model of a multi phase 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, causing the induction machine with squirrel cage to start,
and accelerating inertias. At time tStep a load step is applied.
