Modeling and Simulation of Magnetic Saturation in Induction Motors

It is proved that for different combinations of currents and flux linkages as state variables, there is a common theoretical support that simplifies the obtaining of the mathematical models of the saturated induction machine. Three models are compared: the exact one that introduce the cross- inductance Ldq , the classic one and simplified one for the simulation of the speed reversal process. For Ldq ne ct. and random, the exact method appears compulsory.
