Design criteria and range limits in the development of controlled induction motors

Abstract

Automated design optimization of controlled induction motors for a variety of design tasks in two ranges criteria is performed. Design tasks include consideration of both static and dynamic modes. The changes in variable motor parameters according to the selected criteria and design tasks are defined. A modification of the criteria of electric drive given costs is proposed by using of operation significance coefficient. This allows reconciling of the maximum of midrange efficiency and the minimum of mid-range resulted expenses. Analysis of the effect of inflation coefficient on the value of the reduced costs objective function is carried out. The classification of a design range limits applicable to the development of controlled induction motors is offered. The applying of range limitations in the automatic optimization design program of controlled induction motors is described. The use of range limitations affects the results of the design synthesis of controlled induction motors.
