WIND ENERGY PLANT AND DRIVE DEVICE FOR ADJUSTING A ROTOR BLADE |
摘要 |
The invention relates to a wind energy plant comprising a rotor having a rotor hub which is mounted on a gondola and a plurality of rotor blades. An electric generator is connected to the rotor. The invention also relates to an electric drive device which is designed as a direct drive and used to adjust a rotor blade which is arranged in a concentric manner on the rotor hub in relation to rotor blade bearing and a permanently excited synchronous motor. A stator of the synchronous motor comprises a coil body which is mounted on the motor hub. A rotor of the synchronous motor is arranged at an axial distance with respect to the stator for forming an axially extending air gap. Said rotor also comprises a permanent magnet arrangement on a support plate which is connected to a rotor blade shaft. |
