Abstract: 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).

Abstract: A node structure (12, 14) for connecting two or more convergent members (16, 26) of a lattice frame to each other and to one or more other members of the lattice frame. The node structure (12, 14) comprises a pair of opposed spaced-apart faces (30) that are substantially planar and substantially parallel to each other. At least one pair of root formations (32) with respective central longitudinal axes define an interior angle between them, those axes diverging outwardly for alignment with respective members of the lattice frame and converging inwardly between the faces (30). An inner connecting wall (34) between the root formations (32) of the pair connects concave-curved inner edges (36) of the faces and extends in a concave curve around the interior angle to join the root formations (32) of that pair.

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 preloaded 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).
