Abstract in English: 

Background: The objective of reducing noise and vibrations in modern synchronous drives becomes more and more relevant in view of increasingly stringent performance requirements. Improving the vibro-acoustic performance in certain technical fields such as submarine fleet is of primary importance. The existing methods of frequency regulation do not take into account the influence of stator phase number on vibrating characteristics, and the widespread constructive ways degrade other characteristics of the drive, for example, the slant grooves. Distributed windings and air gap increase weaken the machine field and reduce its energy characteristics. Most of the methods do not take into account the specifics of particular machine geometry, or require rather long and bulky computing operations. In this regard, it is necessary to create methods of optimizing vibronoise characteristics of motors taking into consideration the actual configuration of their magnetic field.

Materials and Methods: The study employed methods of numerical integration and finite element method in the software shell Elcut enabling the development and analysis of engine field models taking account of nonlinear saturation characteristics of the materials.

Results: A magnetic force optimization technique has been suggested based on the structural change of the machine rotor form and synthesis of phase current of a special shape stator. Comparative analysis of the model field patterns has revealed a two-fold drop in radial force magnitude after optimization.

Conclusions: The results of the study are fully consistent with the works in the field of multi-phase asynchronous drives which describe experimental confirmation of analogous field models.The developed methods of forming the magnetic state of an electromechanical system allows optimizing the magnitude of machine magnetic forces, which significantly reduces noise and vibration.

Key words: synchronous electric drive, multiphase drive, vibronoise characteristics, magnetic forces.
