Abstract

The invention relates to a wind turbine having one or more rotor blades (6, 8) disposed on a rotor hub so as to be angularly adjustable by means of a rotary bearing (10, 12), wherein each rotor blade is connected to an adjustment drive for the blade angle adjustment. In order to avoid the gearbox downstream of the drive motors which is necessary in conventional adjustment drives and requires a considerable amount of space and continuous intensive maintenance, according to the invention the respective adjustment drive is designed as a direct drive motor, the rotor of which is connected directly or via coupling means to the rotor blade (6, 8) and the stator of which is supported on the rotor hub (4). In a preferred embodiment the rotor of the direct drive motor is combined respectively with a bearing ring (18, 20) of the rotary bearing associated with the rotor blade (6, 8) to form an integrated structural unit and the stator of the direct drive motor is combined respectively with a bearing ring (22, 24) associated with the rotor hub (4) to form an integrated structural unit, i.e. the rotary bearing and the adjustment drive form an integrated system.
