Background: Noise and vibration reduction of the electric drive is one of the most relevant goals in its development. Methods for solving this problem in the framework of the traditional three-phase systems have been well studied and their capabilities are practically exhausted. One of the new design variants of the electric drive, of the synchronous type, in particular, with improved vibronoise characteristics is its implementation on the basis of the actuating motor with an increased number of phases. However, the known approaches to the synthesis of the electromechanical system on its basis ignore the specificity of the m-phase (m > 3) machine as a control object. Materials and methods: The study has employed mathematical tools of reduced spectral vectors and software package for field simulation by the Elcut finite-element method. Results: It is shown that increasing the number of phases of the actuating synchronous drive with permanent magnets helps optimize its vibronoise characteristics due to reduction of tangential and radial magnetic forces. A procedure of synchronous electrical drive vibronoise characteristics optimization has been suggested, as well as a method of creating a field model using the Elcut environment. Conclusion: It has been shown that increasing the number of phases of the actuating permanent magnet synchronous motor (PMSM) is a promising option for constructing low-noise ED. The suggested variant of constructing a multi-channel automatic control system (ACS) presented here provides radial magnetic forces reduction.
