[0109] figure 1 A wind turbine 100 is shown having a tower 101 raised from a foundation 102 , said tower 101 mounting a nacelle 103 . The wind turbine 100 has a wind turbine rotor 104 with at least one blade 105, in this embodiment two blades 105', 105".

[0110] In the illustrated embodiment, wind turbine 100 is a partial pitch wind turbine, but it may be any wind turbine.

[0111] The wind turbine rotor 104 includes blades 105 mounted within a hub 106 so that the rotor 104 can rotate and delimiting a rotor circumference 107 with a rotor radius equal to the length 108 of the blades.

[0112] Each blade 105 has a mounting end 109 or inner end for mounting the blade 105 on the hub 106 and an opposite free end 110 or outer end.

[0113] The rotor 104 rotates in a plane of rotation about an axis 114 extending within a shaft 115 (not shown) connected to a generator 116 (not shown).

[0114] Blade 105 on partial pitch wind turbine 100 includ...

Abstract

The invention relates to a wind turbine comprising a wind turbine tower provided with a nacelle on top; a wind turbine rotor hub with at least one wind turbine blade rotatably mounted at the nacelle; a shaft coupled to the wind turbine rotor hub and a generator. The generator comprises a rotor having at least one superconducting rotor coil arranged rotatably in relation to a stator having at least one stator coil. The rotor is arranged in a rotor housing and the stator is arranged in a stator housing, where the two housings are separated a rotor-stator gap. The stator housing comprises a stator inner shell and a stator outer shell connected to each other by at least one stator housing end plate. The stator inner shell comprises a first inner shell element attached to a stator iron which in turns is connected to a second inner shell element. A pressure plate is attached to the second inner shell element and the stator outer shell.
