Background. One of the most important tasks when developing modern electric drives is to improve their vibration-noise characteristics. Within the framework of traditional three-phase systems, approaches to solve this problem are well studied and have exhausted themselves to some extent. In this regard, the development of an electromechanical alternating current system based on executive motors with an increased number of phases of the stator winding (m > 3) gives a wide range of new possibilities.
Materials and methods. The author has studied the adjustment characteristics of an m-phase motor based on spectral vectors of electromagnetic parameters reduced to spatial harmonics of the field.
Results. Multi-channel principles for the development of m-phase asynchronous and synchronous electric drives have been proposed. They ensure the targeted formation of the electromagnetic state of the executive motor along all the energy channels as a control object. The ways of its implementation have been considered.
Conclusions. The targeted formation of the magnetic field configuration in the gap of multiphase (m > 3) asynchronous and synchronous motors is one of the effective ways to improve the vibration-noise characteristics of an electromechanical system by reducing tangential and radial forces.
