APPLICATION OF A RELATIVE TECHNICAL LEVEL INDEX METHOD TO INDUCTION MOTOR OPTIMIZATION PROBLEMS

Abstract

On the basis of a method of relative technical level indices with relative geometric controlled variables, analytical expressions are derived to determine the optimum geometric dimensions of the squirrel-cage induction motor active part under criteria of the weight and the cost minimums. Comparative analysis of the mentioned indices for the conventional and the inverted stator and rotor designs is performed.
