A very large portion of the produced electricity get consumed by induction motor applications like pumps, fans and compressors. A major portion of this produced electrical energy can be saved by proper speed control methods, but even with the large savings obtained these approaches, still it is essential and possible to optimize the control technique used in variable speed drivesto optimize the induction motor operations. In an experiment made on 1 kW induction motor (used in variable speed pump system) with energy optimal control, it was found that 10% of the consumed energy can be typically be saved in comparison of constant V/Hz (rated flux) control. This paper produces a review of various possible approaches for operating an induction motor at optimal condition for a particular application. It also gives a brief idea of various software/ hardware tools which are being used in industry.
