07385305 is referenced by 30 patents and cites 79 patents.

The invention relates to a wind power current generator comprising a bearing, a tubular stator that carries a race of the bearing, a tubular rotor coaxial with the tubular stator that can rotate in relation to the stator, a hub connected to the rotor, and at least two blades radially extending away from the hub. According to the invention, the stator and the rotor are formed with substantially tubular cross sections and are concentric to one another. The opposing surfaces of the rotor and stator carry permanent magnets and windings. The stator and rotor extend beyond either side of the magnets and the windings in order to accommodate an antifriction bearing on at least one side. The tubular nature of the rotor and stator allows easy passage of workers within the generator for maintenance thereof and of the blades. Additionally, the tubular nature facilitates air flow through the structure and out the blades, cooling equipment within the structure and aiding de-icing of the blades.
