ABSTRACT:
The system comprises a nacelle mounted to turn about a vertical axis on the top of a mast and carrying a rotary portion which rotates about a substantially horizontal axis in a large diameter bearing. The rotary portion comprises a hub to which blades are fixed. The system has an electric generator comprising a stator and a rotor in the shape of a disk. The rotor is fixed by a connecting member to the hub adjacent the bearing so that the forces exerted by the wind on the rotary portion are transmitted directly to the bearing without passing through the electric generator.
