FIELD: electrical machines; dc motors and geneartors used for electric drives of industrial robots, manipulators, automatic-control systems. SUBSTANCE: permanent-magnet dc machine stator has nonmagnetic frame, pole cores secured to nonmagnetic frame, permanent magnets, external magnetically soft yoke. Round holes made in stator yoke in radial direction receive permanent magnets in the form of hollow cylinders. Magnet hollows accommodate cylindrical pole cores with round pole shoes. EFFECT: enlarged functional capabilities. 2 dwg
