D'ogtyev V. Structural models and methods of synthesis multiphase windings of electrical machines

1) Multiphase windings. 2) Improvements of multiphase windings of electrical machines and methods of their synthesis. 3) Structural analyses and synthesis, theory of sets, theory of groups, harmonic analysis.4) One-coordinate windings generalized structural model, methods of directed synthesis of multiphase windings, particular windings and subsets of windings with necessary properties. 5) On the basis offered generalized model new properties of windings are established and effective methods of synthesis windings with improved parameters are developed. 6) Windings are introduced at modernisation of multi-speed machines of series 4А, АIS and АIR. 7). Electromechanical.
