Electric generator for a wind turbine, inner stator for an electric generator for a wind turbine and wind turbine

Abstract

Electric generator for a wind turbine (1), comprising at least one brake support plate (23) having at least one braking arrangement (21) mounted thereon, an outer rotor (11) which is rotatably mounted with respect to the brake support plate (23), wherein the at least one braking arrangement (21) is adapted to interact with at least one brake disk (22) which is attached to the rotor (11) to brake a relative rotation between the rotor (11) and the at least one brake support plate (23), wherein an airgap securing element (33) is mounted on the brake support plate (23) and adapted to get in contact with the at least one brake disk (22) if a distance between the at least one brake disk (22) and the brake support plate (23) and / or between an inner stator (10) of the electric generator (7) and the rotor (11) is reduced below a predetermined reference value, wherein the at least one airgap securing element (33) is mounted on the at least one braking arrangement (21).
