| 摘要 |
The invention relates to a wind turbine (1) for converting kinetic energy from wind into electrical power, wherein said wind turbine (1) comprises: a rotary part (2, 3, 7) adapted to rotate around an axis of rotation (9) comprising at least one blade (2, 3) for catching the wind, a supporting structure (4, 10, 20) for supporting said rotary part (2, 3, 7) and for fastening said wind turbine (1), said rotary part (2, 3, 7) being ratably connected to said supporting structure (4) so as to allow rotation of the rotary part (2, 3, 7) with low friction to the supporting structure (4). The wind turbine is characterized in that at least one field coil (10, 20) is attached to or integrated into said supporting structure (4), said at least one field coil (10, 20) being adapted to be fed with a direct current (If) so as to create at least one magnetic field (B) with a field direction perpendicular to said axis of rotation (9), said rotary part (2, 3, 7) comprises at least one conduction wire or winding (7) that is attached to or integrated into said rotary part (2, 3, 7), said conduction wire or winding (7) passing said at least one magnetic field (B) to induce electric current (Ii) in said conduction wire or winding, said supporting structure (4) further comprising a rotary electrical connection (6), being adapted to connect said at least one rotating conduction wire or winding (7) of the rotary part (2, 3, 7) to an electrical outlet (8) of said supporting structure. |
