Abstract

Successful optimization processes of highly utilized industrial squirrel cage induction machines enforces fast, reliable and accurate design concepts. Therefore, modern numerical finite element calculation procedures, which incorporate moveable rotor parts, non-linear iron saturation effects and realistic geometric properties, have been systematically established and applied to an induction motor in the time-domain for the prediction of several transient and quasi-steady characteristics. The obtained results have been compared with measurements in order to verify the assumptions within the finite element modeling.
