Abstract
The invention relates to a regulated apparatus for the generation of electrical energy. A wind generator comprises a propeller having fixed blades and a generator connected by a transmission to the propeller and having sets of main and secondary brushes. The hub of the propeller comprises a rotor of an eddy-current brake whose inductor stator is supplied by a current delivered, starting from a certain speed, by the secondary brushes of the generator which are angularly shifted relative to their neutral position.
