FIELD: medical engineering. SUBSTANCE: device has inductor unit having magnetic circuit each section of which is composed of flat segments joined to one another. The number of segments is proportional to the number of phases. Each flat segment has corresponding phase coil . The coils having phase sections of the same name are connected in series. EFFECT: reduced acoustic noise level; reduced current load; improved production method. 3 cl, 1 dwg
