Abstract
A wind generator (1), comprising at least one supporting tower or upright (2), on the upper extremity of which is mounted a swivelling platform (3), has at least two rotary alternators (4) and (5) are installed on said swivelling tower, which said alternators are joined together and connected to shaft (9) and hub (10) of a rotor with two or more blades (11), with a variable setting angle.
