Abstract
It comprises stator segments forming a stator structure and a transverse structure connected to the stator structure and arranged between at least two stator segments. The transverse structure may have reinforcing ribs extending therealong and a handling device at longitudinally opposite portions of the transverse structure. A wind turbine generator comprising a rotor and said stator assembly and a wind turbine comprising such a generator are also provided.
Claims8
A stator assembly for a wind turbine generator, the stator assembly comprising:
- a number of stator segments extending radially inward from a semi-cylindrical frame, the stator segments and frame forming a stator structure,
- a transverse structure arranged to extend along a diameter of the stator assembly,
- the transverse structure comprising
- a perimetric plate connected to the stator structure, the perimetric plate comprising a continuous closed loop structure that extends across the diameter of the stator assembly, the closed loop structure defining a hollow region,
- a cylindrical element for receiving a bearing assembly, the cylindrical element arranged centrally within the hollow region of the closed loop structure such that the perimetric plate engages at least partially around opposite portions of the cylindrical element and portions of the hollow region are defined at opposite sides of the cylindrical element, and
- a flange attaching the cylindrical element to the perimetric plate,
- the stator segments extending radially inward to the perimetric plate,
- wherein the transverse structure is stronger than the stator segments.
