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).
摘要翻译：公开了一种用于风力涡轮机（1）的发电机（5）。发电机（5）包括构造成围绕旋转轴线旋转的转子（3）和邻近转子（3）设置的至少一个定子（4）。每个定子（4）包括至少两个子单元（8），所述子单元（8）沿着转子（3）的移动方向并排布置。每个子单元（8）包括面向转子（3）但与其间隔开的至少一个通量产生模块（9），由此在转子（3）和每个通量产生模块（9）之间限定气隙。子单元（8）可以沿着基本上横向于转子（3）的移动方向的方向相对于彼此移动。这允许子单元（8）以调节气隙的方式移动，而不影响相邻子单元（8）的位置和气隙。由此可以补偿转子（3）的变化，并且可以保持均匀且恒定的气隙。本发明还提供一种包括这种发电机（5）的风力涡轮机（1）和用于在发电机（5）上执行维修的方法。
