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