The purpose of research is to build a model of the electric driving system for threephase squirrel-cage induction motor using oriented electric field method so as to control both the speed , flux and current, ( PI ) controllers was used . The machine model has been formed based on the equations of the machine written in the stationary coordinates . To complete the process of control without measuring the rotor flux , a model of flux from the measured values of stator current and rotor speed was build, and it can be measured directly .
