FIELD: electric engineering, in particular - electric machines and electric drive.
SUBSTANCE: in electric machine, containing a rotor made of magneto-conductive material with constant magnet, polarity of which is alternated in tangential direction, and a stator, magnetic duct of which is made of magneto-conductive rings and longitudinal closing packets, and its windings are made of circular sections, distributed in axial direction and positioned between two adjacent magneto-conductive rings, in accordance to invention, control winding is positioned, consisting of sections, which are interconnected in such a way, that magnetization force signs of these sections alternate in tangential direction.
EFFECT: ensured control of output voltage amplitude, reduced vibrations and acoustic noise of the machine, and also reduced hazard of ignition of the machine in case of short circuit in windings.
