FIELD: electricity.
SUBSTANCE: invention relates to wind power engineering. Windmotor contains vertical shaft, lower bracket arranged on shaft and upper bracket with hub, three outward bent blades fixed by both ends to upper and lower brackets, and connected to electric generator. Blades are made curved in shape described by formula of chain line of equal resistance. Upper and lower brackets have a streamlined profile.
EFFECT: invention is aimed at improvement of conversion efficiency of wind flow kinetic energy into mechanical energy of rotation and improvement of mechanical strength of wind rotor.
