A device (2) for harnessing the energy of wind comprises a mast (4) carrying a rotor (8) which rotates, under the action of the wind, about a vertical axis of rotation (78) and is provided with a plurality of vertical rotor blades (12) at a distance from the axis of rotation (78); and a device (14) for converting the kinetic energy of the rotor (8) into electrical energy. The device (14) comprises a first functional part (45) and a second functional part (47) which can rotate relative to each other and are separated by an air gap (54), one of the two functional parts (45, 47) having an exciter system (50) and the other functional part having a conductor system. The mast has an essentially horizontal first large-diameter support ring (44) for the first functional part (45) and the rotor (8) has an essentially horizontal second large-diameter support ring (46) for the second functional part (47). |
