ABSTRACT OF THE DISCLOSURE: A turntable direct-drive system in which a cylindrical rotor having an inverted U-shaped cross sectional configuration is carried by a turntable shaft, and two stator cores with windings mounted thereupon are disposed at opposite sides, respectively, of the side wall of the cylindrical rotor and spaced apart thereform by a distance suitable to exert the driving force to the side wall of the cylindrical rotor. A turntable is supported by the turntable shaft or on the top of the cylindrical rotor directly or through a plurality of protections extended therefrom or a plurality of elastic supporting members attached thereto so that the turntable may be maintained at a level and vibrations thereof may be minimized.
