1. A wind-driven machine for generating power, of the type comprising a tower having a top end wherein a gondola is arranged and a rotary equipment mounted in the gondola, the rotary equipment having wind collecting blades, wherein said rotary equipment comprises:
an electric power generator comprising an inner stator fixed to said gondola and an outer rotor enclosing said inner stator, magnetic poles and winding for generating electric power, with the poles and the winding being arranged in said inner stator and in said outer rotor, a plurality of supporting cups, one for each blade, which are equidistantly fixed in said outer rotor of the generator, said supporting cup having a truncated cone shape, wherein the cone has a minor base fixed to said peripheral wall of the outer rotor, and a major base being radially open outwards and a blade pitch regulating hub rotatively mounted within each of said supporting cups, with each wind collecting blade being connected to one of said pitch regulating hubs, wherein said blade pitch regulating hub comprises a body of conical general configuration inserted inside a corresponding supporting cup, said body of conical general configuration having a major base raising from above said open major base of the supporting cup.
