Efficiency enhancement of induction motor using soft computing technique

Abstract

Induction motor is predominently used as driver for industrial and commertial applications.Although induction motor has many significance it offers poor efficiency when the applied load on a motor is low. This factor limits the application of induction motor for lighter torque conditions. So its become mandatory enhance the efficiency of motor when the applied load is lesser. It is possibleto improve the performance of a motor by means of mathematical modelling. In this the first principle model of an motor is developed. The efficiency of a motor for various load condition is calculated from the data obtained from mathematical model by considering all the losses associated with motor. The performance of model is evaluated for different control algorithms like fuzzy logic and Particle swarm optimization.
