A wind turbine and to a method for installing a generator for a wind turbine, in which a nacelle and a mainframe for installation of, e.g., a generator and a main shaft, is installed on top of a tower. The nacelle further has a nacelle cover extending over the main frame from the hub and to a rear end, covering components installed on the main frame. The nacelle cover has at least a first part and a second part, the first part having a interface for engagement with a corresponding interface on the second part, the second part of the nacelle cover housing a generator as one unit. By having the generator and the second part of the nacelle cover as a single unit, installation can be performed in one go and then only one hoist with a crane is needed.
A wind turbine comprising a nacelle, said nacelle being installed on top of a generally vertical tower, said nacelle comprising a mainframe suitable for installation of a number of components including a generator, a main shaft, and a hub comprising a number of blades, said nacelle further comprising a nacelle cover extending over said main frame from the hub and to a rear end, covering components installed on the main frame, wherein that said nacelle cover comprising at least a first part and a second part, said first part having an interface for engagement with a corresponding interface on said second part, where said second part of the nacelle cover is housing a generator, and where said generator and said second part of a nacelle cover is construed as one unit.
Method for assembling a generator unit and for installing such a generator unit on a wind turbine on a mainframe in a nacelle, said nacelle and mainframe being installed on top of a generally vertical tower, said mainframe being suitable for installation of further components such as a shaft and a hub, said shaft being directly or indirectly connected to said hub, where said hub comprises a number of blades, further said nacelle comprises a nacelle cover and said generator unit comprises at least a generator having a stator and a rotor, said stator having connection means for connection to said mainframe, and said rotor having connection means for connection to said shaft, wherein that said method for assembling and installing a generator unit at least comprises the steps of:
