Design optimization of induction motor using hybrid genetic algorithm 'a critical analyze'

摘要

The aims of this paper is describes the procedure to determine the design of three phase electrical motors. The originality lies in combining a motor design program and employing a Hybrid Genetic Algorithm (HAGs) technique to obtain the maximum of objective function such as the motor efficiency. A method for evaluating the efficiency of induction motor is tested and applied on 2.2 kW experimental machines; the aforementioned is called equivalent circuit method (EC-M) and based on the analysis of the influence losses. After that, the optimal designs are analyzed by finite element method (FEM) and compared with results of another method which is genetic algorithms (GAs) optimisation technique, was done to demonstrate the validity of the proposed method.
