3.7 Wind Generators: There are three main parts in horizontal axis wind turbines: (1) a rotor‚ (2) an alternator‚ and (3) a tail. The rotor blades are attached to a central hub covered by a nose cone that improves aerodynamics. Three blades are generally present in upwind generators. This entire assembly rotates when wind blows past the blades‚ hence the name “rotor.” In many small wind turbines the rotor is coupled to a shaft which is coupled to an alternator‚ a device that produces AC electricity
