Abstract: A wind motor is disclosed wherein mounted on a support structure is a shaft carrying a rotor comprising blades connected with the shaft and extending longitudinally relative thereto at an angle to the longitudinal axis thereof. Each of the blades is connected to the shaft through a girder having the shape of a triangular pyramid with one of the rods making up this pyramid extending from an apex thereof along the longitudinal axis of the blade to be connected therewith and with the end of the shaft at the outlet of the windstream, whereas two other rods extending from this apex are secured on a hub positioned at the end of the shaft which faces the windstream tangentially to this hub.
