DIRECT-DRIVE WINDMILL Russian patent published in 2014 - IPC F03D3/00 

FIELD: engines and pumps.

SUBSTANCE: invention relates to wind-power engineering and can be used for electric power production. Proposed windmill comprises tower with turntable, windwheel, rotor elements, stator, guides, pole tips and coil of two types: working and excitation coils alternating in circle. Ends of low-rpm windwheel blades are equipped with high-rpm windwheels furnished with electromechanical rotor elements. Stator is secured ay vertical flange of angle-piece secured with turntable moving part while bar with the guide is secured at horizontal flange of said angle-piece. Thus, said stator is mounted at turntable in circular zone of rotor elements nearby low-rpm windwheel shaft.

EFFECT: higher power output, simplified shape of stator elements.
