Beschreibung
Zusammenfassung:	A stator (20) for an electric generator (11), in particular for a wind turbine (1), comprises a structure (21, 22) having a circumferential cavity (23) for circulating a cooling medium, the circumferential cavity (23) extending between a plurality of inlet cooling ducts (33) and an outlet opening (25) for letting the cooling medium exit the stator (20). A plurality of radial sections (IV-IV, V-V, VI-VI) of the circumferential cavity (23) have different areal extensions, the radial section (VI-VI) at the outlet opening (25) having the greatest areal extension.
