IVAN KOSTOV, Abstract An approach for modeling of induction motors IM in the MATLAB Simulink. software using an equivalent AC circuit has been proposed For physical modeling of the. equivalent circuit of the IM has been used the MATLAB SimPowerSystems software media. This way the advantages of both software environments have been combined for the exact. description of the physical processes in electromechanical systems and for control. purposes A model to IM in the fixed coordinates systems has been developed The model. can be used to investigate the symmetrical modes and processes in electric drives which. the existing models can not simulate The validity of the simulation results is confirmed. using simulation procedures of verification The approach is applicable to other machines. and coordinate systems, Key words induction motor summarized electric machine modeling simulation. coordinate and phase transformations Clarke transformation.
