Modeling and experimental characterization of saturation effect of an induction machine

This paper presents a new experimental measurement method of the electrical parameters, shown from the stator, of a squirrel cage induction machine in accordance with its magnetic saturation level. It develops a new two-phase saturated model of the induction machine which uses these measured electrical parameters. This new measurement method has a very big advantage in the industrial domain. It avoids the use of a finite elements calculation program which takes much more time to calculate the electrical parameters. The experimental measurement method is applied on a 4 KW squirrel cage induction machine. A comparison between the real dynamic response of this machine, and the dynamic response of the new two-phase saturated model shows that the obtained results are very encouraging
