FIELD: controlled electric drives of robotized systems in welding, mounting, and stockpiling engineering. SUBSTANCE: device has stator 2 with multiphase winding 3 and squirrel-cage rotor 6 mounted on hollow shaft 7. Hollow shaft 7 accommodates linear-displacement rod 8 with ball-and-screw assembly coupling rod 8 with hollow shaft 7. The latter carries braking disk 12 of electromagnetic brake with slits. When slit runs over U-shaped core of instrument transformer, metering magnetic flux in it and respective signal across its secondary winding are brought to minimum. EFFECT: enlarged functional capabilities. 3 dwg
