摘要： A generator (5) for a wind turbine (1) is disclosed. The generator (5) comprises a rotor (3) configured to rotate about a rotational axis, and at least one stator (4) arranged next to the rotor (3). Each stator (4) comprises at least two subunits (8), the subunits (8) being arranged side-by-side along a moving direction of the rotor (3). Each subunit (8) comprises at least one flux-generating module (9) facing the rotor (3) but spaced therefrom, thereby defining an air gap between the rotor (3) and each flux-generating module (9). The subunits (8) are movable relative to each other along a direction which is substantially transverse to the moving direction of the rotor (3). This allows a subunit (8) to move in a manner which adjusts the air gap without affecting the position and the air gap of a neighbouring subunit (8). Thereby variations in the rotor (3) can be compensated and a uniform and constant air gap can be maintained. The invention further provides a wind turbine (1) comprising such a generator (5) and a method for performing service on a generator (5).

摘要： A transition structure for a tower comprises a plurality of panels that each includes a panel body having opposed upper and lower ends, a lower mounting surface at the lower end, an upper mounting surface at the upper end, and a pair of lateral mounting surfaces at lateral edges. The upper mounting surfaces are generally planar, and the panel bodies taper from their upper mounting surface to their lower mounting surface. Each panel is mounted to at least another of the panels at corresponding lateral surfaces to form, with the upper ends, the shape that conforms to the lower end of the tower to be supported. The transition structure also comprises a plurality of footings, each having an upper end mated to the lower mounting surface of one of the panels, a lower end configured to mate with a post of a foundation, and a footing body between the upper and lower ends.

摘要： A generator (5) for a wind turbine (1) and a wind turbine (1) are disclosed. The generator (5) comprises a rotor (3) configured to rotate about a rotational axis, and at least one stator (4) arranged next to the rotor (3), each stator (4) comprising at least one flux-generating module (9) facing the rotor (3) but spaced therefrom. The flux-generating module(s) (9) is/are mounted on a stator support structure (7, 10). The stator support structure (7, 10) defines a pre-loaded spring force acting against magnetic forces occurring between the rotor (3) and the flux-generating module(s) (9) during operation of the generator (5). The preloaded spring force is adjustable, e.g. by means of a piston arrangement (17). Thereby it is possible to maintain a preloaded spring force which is capable of acting against the magnetic forces occurring between the rotor (3) and the flux-generating module(s) (9), even if operating conditions are changed. Furthermore, the preloaded spring force may be adjusted to compensate for inaccuracies originating from production tolerances of the stator support structure (7, 10). A uniform and constant air gap can thereby be maintained between the rotor (3) and the flux-generating module(s) (9).

摘要： A wind turbine comprising a nacelle (1) is disclosed. The nacelle (1) accommodates at least a generator (3) and power electronics electrically interconnected between the generator (3) and a power grid. At least one power electronic component (10, 11, 12) is removably arranged in the nacelle (1) in a region positioned between a floor level of the nacelle (1) and a lower limiting surface, e.g. a bottom wall, of the nacelle (1). The space available in the interior parts of the nacelle (1) is thereby utilised to a greater extent than in prior art wind turbines, and replacement of a power electronic component (10, 11, 12) can be performed using ordinary lifting equipment. Furthermore, the risk of injury to maintenance personnel is reduced.
