摘要

annular generator of a wind power installation, method of controlling a wind power installation, and, wind power installation the present invention relates to an annular generator of a wind power installation comprising a stator having a stator ring that extends peripherally to receive stator windings and a rotor rotatably rotated around an axis of rotation in relation to the stator, in which the stator ring has cooling passages to cool the stator by an air flow. the invention also relates to an annular generator of a wind power installation having a stator, a stator ring that extends peripherally to receive stator windings, a rotor mounted pivotally in relation to the stator and a stator bell connected to the ring stator to provide a pressure chamber with a high or reduced pressure to provide an air flow through and / or along the stator and / or rotor to cool the annular generator, in which the stator bell has at least one opening fan provided with a fan and the fan is movably mounted by means of a movement mechanism to temporarily open the fan opening for maintenance purposes and / or to allow the passage of a person.
