Abstract The present invention concerns a ring generator of a wind power installation comprising a stator having a peripherally extending stator ring for receiving stator windings and a rotor mounted rotatably about an axis of rotation relative to the stator, wherein the stator ring has cooling passages for cooling the stator by an air flow. The invention further concerns a ring generator of a wind power installation having a stator, a peripherally extending stator ring for receiving stator windings, a rotor mounted rotatably relative to the stator and a stator bell connected to the stator ring for providing a pressure chamber with an increased or reduced pressure for providing an air flow through and/or along the stator and/or rotor for cooling the ring generator, wherein the stator bell has at least one fan opening provided with a fan and the fan is mounted movably by means of a motion mechanism to temporarily open the fan opening for maintenance purposes and/or to allow a person to pass.
