Wind turbine with a generator
View Patent ↗A wind turbine with a generator includes a rotor with permanent magnets and a stator with stator coils mounted on a stator support structure. The stator support structure includes a base structure on which circular connection structures are mounted with their inner perimeter, whereby a stator base structure is connected to the outer perimeter of the circular connection structures.
1. A wind turbine with a generator, comprising:
a rotor comprising permanent magnets and arranged around an axis of rotation;
a stator arranged radially inward from the rotor, the stator comprising:
stator coils;
a circular inner base structure;
a circular outer base structure on which the stator coils are mounted; and
a plurality of connection structures, each of the plurality of connection structures separated axially and radially extending between the circular inner base structure and the circular outer base structure forming a hollow chamber between the circular inner base structure, outer base structure and the plurality of connection structures,
wherein the hollow chamber is ventilated, and
wherein the plurality of connection structures are connected to the circular inner base structure and connected to the circular outer base structure.
2. The wind turbine according to claim 1 ,
wherein the inner base structure comprises radially protruding flanges on which the connection structures are mounted.
3. The wind turbine according to claim 2 ,
wherein the plurality of connection structures are circular.
4. The wind turbine according to claim 2 ,
a hub; and
a bearing assembly,
wherein the circular inner base structure comprises further connection flanges at axial ends of the circular inner base structure for connecting to the hub or the bearing assembly.
5. The wind turbine according to claim 1 ,
wherein the plurality of connection structures are connected to the circular inner base structure and/or the circular outer base structure by bolted connections.
6. The wind turbine according to claim 1 ,
wherein the plurality of connection structures are connected to the circular inner base structure and/or the circular outer base structure by welding.
7. The wind turbine according to claim 1 ,
wherein the plurality of connection structures are connected to the circular inner base structure such that each of the plurality of connection structures are parallel.
