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 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).
