Embodiment Construction

[0049] Figure 5 is a side view showing an example of the overall structure of the wind energy converter. The wind energy converter 1 comprises: a tower 2 arranged on a foundation 6; a nacelle 3 arranged on the upper end of the tower 2, the nacelle 3 being able to rotate about a substantially vertical axis B; and a rotor head arranged on the nacelle 3 The rotor head 4 includes a hub (not shown) for fixing the rotor blades 5, and the rotor head 4 is rotatable about a substantially horizontal axis A.

[0050] Blades 5 extending radially from the axis of rotation A are attached to the rotor head 4 at different circumferential angles. Wind force supplied to the blades 5 from the direction of the variable axis of rotation A of the rotor head 4 causes the rotor head 4 to rotate about its axis of rotation.

[0051] Figure 1a and 1b is a cross-sectional view showing an example of the internal structure of the nacelle, where, Figure 1a Middle is a longitudinal section along the ax...

Abstract

An apparatus for wind energy conversion includes a nacelle having a main frame, the main frame having a lower part and an upper part joined to the lower part, the upper part having a first strap extending across the lower part; a stator disposed within the nacelle; a rotor disposed within the nacelle; a mounting surface attached to the main frame and defining a rotor space, the mounting surface having a first side-face that exposes the rotor space; and a flange rotatably supported on the main frame and including a first end connected to the rotor. The rotor is cantilevered from the flange into the rotor space from the first side face.

Description

technical field [0001] The present disclosure relates generally to wind energy converters and in particular to generators, nacelles and installations to the nacelles of wind energy converters. Background technique [0002] A wind energy converter is a rotating machine that converts the kinetic energy in the wind into electricity and supplies the electricity to the grid. [0003] A wind energy converter usually includes a nacelle arranged on a tower. The nacelle (also called "pod") comprises a rotor head equipped with blades and a main shaft, also called hub, connected to the rotor head, which shaft rotates integrally with the rotor head. In addition, the nacelle can be rotated about a vertical axis to actively or passively follow the direction of the wind. [0004] The first nacelle also includes a gearbox connected to a main shaft that rotates when receiving wind power supplied to the blades and a generator driven by an output shaft from the gearbox. According to the win...
