Abstract
A wind machine mounted on a vertical mast (2) and having a wind-driven turbine (1) co-operating with an alternator to generate electrical power, this turbine (1) being fitted with slanting blades (6) mounted on a large-diameter hub (7) with a horizontal axis, the generators of which are located along the trunk of a cone facing the wind, characterised in that the alternator comprises, on the one hand, a magnetic rotor (4) secured to the hub (7), preferably on a level with the maximum available diameter, and on the other hand a stator (5), adjacent to the rotor (4), with magnetic coils distributed in a partial or full circle, and secured to a stationary frame (22) joined to an encircling hood (9) extending the hub (7) coaxially, the blades (6) being shrouded in the vicinity of their ends (55) by a relatively short, divergent, circular fairing (8) mounted concentrically with the hub (7).
