Abstract
A wind turbine nacelle including an outer cover defining an interior volume within which is housed a powertrain assembly comprising: a gearbox including an input shaft and an output shaft which are aligned on a common rotational axis, an electrical power generator connected to the output shaft of the gearbox. The power generator includes a generator cabinet that encloses, in an internal chamber, a stator at a radially outward position and a rotor in a radially inward position, the rotor being rotatable about the common rotational axis. The rotor comprises: a cylindrical field structure coupled to a rotor support frame; a gearbox connection flange that couples to the gearbox output shaft by a first fixing array; wherein the generator cabinet is provided with an opening that permits maintenance personal to gain access fully inside the internal chamber, and wherein the internal chamber is configured to allow maintenance personnel to access at least the first fixing array that couples the gearbox output shaft to the gearbox connection flange from a position fully inside the internal chamber.
