The article presents the results of the software of the automated synthesis of two-and three-phase windings with a reduced level of asymmetry. The necessity of using such a weakly asymmetric windings periodically arises on the enterprises specializing in the repair of electrical machines, so the task of such symmetrize windings design is relevant. Algorithm of synthesis of these multi-phase windings is based on balancing - achieving of practical symmetry on harmonics symmetry that ensures the correct application of the method of symmetrical components to perform a detailed harmonic analysis of the winding MDS. Implementation of this algorithm in manual mode requires multiple graphic design of vector diagrams and performing of repetitive routine calculations, therefore characterized by higher labor input. The proposed software is characterized by a user-friendly interface. Both automated and manual input of initial data, as well as their operational adjustment are provided. Visualization module of vector diagrams eliminates the need of manual graphic design, on the order reduces the time required in the process of balancing using the method of successive approximations and provides almost complete symmetry by working harmonica. On the second stage the compliance of detailed harmonic analysis and printing of the obtained results or saving in files are provided so you can use them for subsequent determination of operational properties of electric machines, in which such winding are used. Effectiveness of the developed software is illustrated by the example of symmetrize three-phase winding synthesis with demonstration of performance technology of each stage of design and comparing of its electromagnetic properties before and after balancing.
