SUMMARY ALGORITHMS AND PROGRAM OF OPTIMUM DESIGN OF THREE-PHASE

SQUIRREL CAGE INDUCTION MOTOR BASED ON EFFICIENCE MAXIMIZATION

WITH ARTIFICIAL NEURAL NETWORKS

Doan Due Tung, Nguyen Ngoc My, Nguyen Thai Bao, Dang Thi Tu My

The design parameters of three phase squirrel cage induction motors can be divided

into three main groups: the first one are basic parameters such as length of the core and an

outer and inner diameter of stator iron core; the second group are the parameters of stator

winding wire such as the number and diameter of winding wire; the third one are the dimensions

of stator and rotor such as stator and rotor's slot height, slot breadth and tooth breadth

These parameters are interdependent, varying from min value to max value for the

designer's choice which has great effect on different copper and iron loss Therefore, it is

necessary to select the most appropriate parameters so that copper and iron loss get min value

This article presents the algorithms and program of optimum design of three-phase squirrel

cage induction motor based on efficience maximization with artificial neural networks
