Background/Objectives: Three phase induction motors have been the workforce for several industrial, manufacturing, propulsion and transportation applications for the past several years. Energy efficient operation of induction motors is the important task in industries.The objective of the present paper is to provide energy efficient operation of induction motors using soft computing techniques. Methods/Statistical analysis: A fuzzy logic and firefly algorithm based hybrid technique is used for performance improvement of a.c.voltage controller fed three phase induction motor drives. Simulation is done by using matlab software. Findings: It is shown that the conventional search method for reaching the best efficiency point has got many drawbacks. These demerits are overcomed using the proposed softcomputing techniques. Application/ Improvements: Improvement in motor efficiency and power factor is achieved and the motor always operates in the energy efficient region.
