The mi proved lgorithm is tested by three cl ssic l m them tic l ex mp les. Accord ing to the fe ture of 3ph se induction motors, m them tic lmodel of optmi um de sign of 3ph se induction motors is est blished. The lgorithm is pplied to the opti m l design ofY seriesmotors. The resu lts show th t IRGA c n mi prove the oper tion perform nce nd decre se the econom ic costs obviously, nd these show th t the lgo rithm is reli b le, v lid nd su it b le to the pplic tion in the engineering.
