المستخلص: In the industries, induction motors are the commonly chosen due to their efficiency, reliability, strength, cost and rugged building. The main percentage of spent energy in manufacturing is spent by induction motors. Therefore, even a modest development in the energy efficiency of induction motor drives can suggest large energy-savings. In this study, efficiency improvement technique is produced for squirrel cage induction motor that works at less than 75% of its full load taking the advantage of the core loss which consider constant losses and make them variable. The improvement is achieved over managing the voltage administered to the stator winding over the use of the three phase AC voltage controller. Voltage control scheme is developed by tracking the change in voltage and current and determined the reference slip, error of slip will be input to fuzzy logic controller and sex back-by-back thyristors will be trigging through the output signals of fuzzy logic controller to get the best voltage that gives the best efficiency for specific load torque. The simulation proofs are done in MATLAB/Simulink. The results show that the proposed scheme gives high improvement in efficiency at light and medium load and gives a good energy-savings.
