Currents System for Efficient Mathematical Modeling of an Induction Motor Using the Field Analysis

The expressions for determining the rotor currents of the circular model are given using the field analysis with existence of the spectrum harmonics of the stator magnetomotive force (MMF). Expressions were developed for the definitions of winding data and the appropriateness of using a calculated model of a sinus stator winding in order to increase the efficiency of mathematical modeling using the equivalent of a field model with a fixed rotor and slip frequency using a circular model.
