	Efficiency improvement is an important challenge for electric motor driven systems. For an\&nbsp;induction motor, operation under rated conditions (at\&nbsp;rated load with rated flux) is very efficient. However,\&nbsp;in many situations, operation with rated flux causes low\&nbsp;efficiency especially at light load ranges. In these applications, induction motor should operate at reduced\&nbsp;flux which causes a balance between iron losses and\&nbsp;copper losses leading to an improved efficiency. This\&nbsp;paper concerns energy optimization, i.e. efficiency improvement is carried out via a controller designed on\&nbsp;the basis of imposing the rated power factor, by finding a relationship between rotor flux and torque current component which can optimize the compromise between torque and efficiency in steady state as well as in transient state. Experimental results are presented\&nbsp;to prove the effectiveness and validity of the proposed\&nbsp;controller.
