Development of Induction Motor Efficiency Model and Improving at Low Load Condition using Controllers

Induction motor is the electrical drives which are widely used in major industrial applications. Generally efficiency of the induction motor is poor at lower load condition. It is necessary to improve the efficiency for the better performance that is possible with the modeling of an induction motor. In this work the mathematical model of an Induction Motor is developed. From the parameters obtained from the model, efficiency can be. calculated from no load to full load condition considering all motor losses including Stray loss, Friction loss etc. Efficiency has been improved by using conventional and fuzzy optimization technique. The performance of developed induction motor model is analyzed with various parameters like torque, speed, current and various losses.
