摘要： A passive magnetic bearing employs eddy currents in a copper core between neodymium annular magnets to support the copper core and an associated rotating shaft. The copper core has an annular flange that is coaxial with a hollow cylinder. The hollow cylinder supports a rotating shaft. An annular iron core is coaxial with and surrounds the annular flange. Annular neodymium magnets surround the upper and lower portions of the hollow cylinder. In some embodiments a touch-down bearing is made up of an upper and a lower bearing race that are spaced away from the upper surface and lower surface of the annular flange. The core rotates over the bearing race(s) until sufficient magnetic flux is generated to support the copper core and hence the shaft. Once spinning, a magnetic field is generated in the copper core.

摘要： Wind turbine systems with wind directors are disclosed. The wind director is configured to simultaneously reduce drag force applied to a returning blade and increase force applied to an advancing blade. In some embodiments, the wind director includes an inlet having an inlet width configured to receive wind at a proximal end, and an outlet having an outlet width on a distal end opposite the proximal end. The wind director is configured to position near a wind turbine such that wind exiting the outlet is applied to an advancing blade of the wind turbine. Furthermore, the wind director provides a barrier to a returning blade opposite the first blade, thereby reducing drag force applied thereto. The wind director may further comprise a secondary duct which has an angled outlet and is configured to apply an additional force to the returning blade.

摘要： Methods, systems, and devices are disclosed for wind power generation. In one aspect, a wind power generator includes a support base; inductors positioned over the support base in a circular array; an annulus ring track fixed to the base support and providing a circular track around which the inductors are located; an annulus ring rotor placed on the annulus ring track and engaged to rollers in the circular track so that the annulus ring rotor can rotate relative to the an annulus ring track, in which the annulus ring rotor include separate magnets to move through the circular array of inductors to cause generation of electric currents; and a wind rotor assembly coupled to the annulus ring rotor and including wind-deflecting blades that rotate with the rotor and a hollow central interior for containing a wind vortex formed from deflecting wind by the blades to convert into the electric energy.

摘要： A high performance hybrid turbine is provided which has an impeller towards which a fluid flow of water, air, or other fluid is conveyed for rotation of the impeller around an axis of rotation. The impeller exploits the thrusts that the fluid flow exerts on the elements constituting the impeller and the thrusts generated by a certain number of airfoils provided inside the elements of the impeller. The high performance hybrid turbine, if used as a wind turbine, can operate at much higher wind speeds than conventional wind turbines.

摘要： Proposed is a wind turbine having a vertical axis rotor mounted in a fixed cylindrical housing provided with outwardly opening shutters. The rotor consists of a rotating core comprising core blades fastened between two circular bases and forming a Ugrinsky rotor, and an annular impeller configured for independent rotation about said core. The impeller comprises impeller blades fastened between two ring-shaped bases and forming a continuation of the core blades, wherein common inter-blade channels are formed which narrow toward the centre of the rotor. Also proposed are wind power stations based on the wind turbines described above, said turbines being mounted vertically one above the other to form a generating tower, or being mounted on a facade of a high-rise building. Technical result consists, in particular, in increasing the efficiency of the wind turbine and making it possible to incorporate wind power stations into an urban environment.

摘要： The present disclosure relates to an apparatus (10) for wind power generation comprising at least one primary wind duct (12); at least one secondary wind duct (14); at least one pressure-balancing and guiding unit (14); at least one primary blade unit (20); at least one booster and generator unit (22); at least one secondary blade unit (24); and at least one extractor (26). Characteristically, a counter-rotating motion is created between the primary blade unit (20), the secondary blade unit (24) and the components of the booster and generator unit (22), which causes an increase in the velocity of the wind flowing through the apparatus (10) and a resultant increase in the impact of the high velocity wind on the blades; further amplifying the self-reinforcing effect occurring at each stage of the apparatus (10).

摘要： A flow turbine rotor whose operation is based on aerodynamic profiles with leading and trailing edges clearly defined by their construction, adapted for nominal operation at specific speed blade speed greater than 1.5 of the incoming wind speed, characterized in that the angle angle α, measured as a shift in the blade rotation axis (1) between the angular position of the blade trailing edge, from ¼ to ½ of the rotor height is at least 20 percent smaller than the angle β, measured as a shift in the blade rotation axis (1) between the angular position of the trailing edge of the blade, from ½ to ¾ of the height of the rotor.

摘要： A vertical wind turbine that includes a plurality of vertical vanes which is secured to a vertical vane axis so as to be rotatable independently of one another about a respective vane rotational axis and which are rotatably mounted about a vertical rotor rotational axis on a common circular path. A method for operating a vertical wind turbine, in which method pitch angles of vertical wind turbine vanes driven about a respective vertical vane axis are specified. The vertical wind turbine is operated in a particularly efficient and material-preserving manner by control of the pitch angles, at least in a partial load mode of the vertical wind turbine, such that the vanes rotate with a substantially constant tip-speed ratio.

摘要： The present disclosure is directed to towerless vertical-axis wind turbines with pre-tensioned rotors. The present disclosure is further directed to a vertical-axis wind turbine (VAWT) with supported blade ends (e.g., Darrieus type) which replaces the center tower with tensioned supports, such as tensioned guy wires, and blade pre-load.
