Abstract

The invention relates to an electric generator (7) for a wind turbine (1), comprising a stator (11), a rotor (10), which is rotatably mounted with respect to the stator (11), and an air cooling system (32) for guiding an airflow flowing along an airpath (33) which extends through the electric generator (7), wherein the stator (11) comprises at least one structural component (21) having a hollow cross sectional profile and at least one first opening (39) and at least one second opening (40), wherein each of the openings (39, 40) leads into a hollow interior of the respective structural component (21), wherein the at least one first opening (39) is arranged on or fluidly communicates with a first location of the airpath (33), wherein the at least one second opening (40) is arranged on or fluidly communicates with a second location of the airpath (33), wherein within the at least one first opening (39) and/or within the at least one second opening (40) at least one sealing device (38) is arranged which prevents the airflow from flowing through the interior.
