Abstract

This invention provides a nacelle of a wind energy converter and a corresponding mounting method of a nacelle of a wind energy converter and a generator for a wind energy converter. The nacelle includes a main frame; a generator including a stator and a rotor; a generator housing attached to the main frame and at least partially enclosing the stator and a rotor space; wherein the generator housing (20; 20′) has a first and second side face (S1, S2); wherein the first side face (S1) of the generator housing (20; 20′) exposes the rotor space (21); and a flange rotatably supported on the main frame and having a first end which is connected to the rotor; wherein the rotor extends into the rotor space (25) from the first side face (S1) without being supported in the generator housing.
