FIELD: engines and pumps.
SUBSTANCE: wind-driven motor includes vertical rotation axis with six blades fixed on it in two tiers. Each blade is made in the form of a cone pinched on one side, in which one face of pyramid remains and it is somewhat continued and its protruding end is attached to the axis. Blades are attached to each in each tier by means of six rectangular guide shields. Wind-driven motor is capable of effective operation even at weak winds with minimum velocity of 2.5 m/sec.
EFFECT: improving the operating efficiency by means of effective trapping of incoming air flow and reducing the number of vortexes in cavities of the blade.
