The result of the low nacelle weight is a simplified transport, a simplified setup of the wind energy plant and favourably priced structural supports.
The drive train concept of the FL 3000 is based on the proven Compact Drive Train of the FL 2500. This construction design, compared with other drive train concepts, is more compact and lighter, the bearing forces in the rotor bearing are smaller due to a wider support basis and the gear casing is decoupled from the load-deformations of the rotor bearing. The "HybridDrive" is used as gear for the FL 3000, an innovative concept of Winergy AG. The compact HybridDrive is put together by a two-level planet gear and a medium speed permanent magnet synchronous generator. The setting up of the first prototype FL 3000 with a rotor diameter of 120 m is planned for 2012.
