The invention relates to a wind turbine with a generator and a method of assembling a generator thereof, wherein the generator comprises a rotor rotatably arranged relative to a stator. The rotor comprises a plurality of superconducting pole units arranged on a back iron which is spaced apart from a rotor structure by a number of thermally insulating plates or beams. Said plates or beams are located between either ends of the rotor and orientated relative to the rotational direction of the rotor. Each plate has a first end firmly connected to another first beam extending in an axial direction and a second end firmly connected to another second beam also extending the axial direction. The first beams are further firmly connected to the back iron while the second beams are further firmly connected to the rotor structure. The thermally insulating plates or beams provide a flexible and cheap support interface that is able to adapt to the tolerances of the individual components.

Wind turbine with a superconductive generator having an improved thermally insulating structure

A wind turbine having a wind turbine tower with a nacelle; a wind turbine rotor hub with at least one rotatably mounted wind turbine blade; a shaft coupled to the wind turbine rotor hub and a generator. The generator has a rotor having at least one superconducting rotor coil arranged rotatably relative 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, the housings being separated by a rotor-stator gap. The stator housing has a stator inner shell and a stator outer shell connected together by at least one stator housing end plate. The stator inner shell has a first inner shell element attached to a stator iron that is connected to a second inner shell element. A pressure plate is attached to the second inner shell element and the stator outer shell.

The generator has a rotor with at least one superconducting rotor coil arranged rotatably relative 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, the housings being separated by a rotor-stator gap. The stator housing has a stator inner shell and a stator outer shell connected together by at least one stator housing end plate. The stator inner shell has a first inner shell element attached to a stator iron which is connected to a second inner shell element. A pressure plate is attached to the second inner shell element and the stator outer shell.

Nacelle cover and spinner

The invention relates to a nacelle that is releasably attachable, the nacelle being adapted for suspension of the nacelle between at least two wheel sets as completely or partly self-supporting suspension.

Method of transportation of a wind turbine nacelle and use thereof

The invention relates to a wind turbine having rotating means including at least two wind turbine blades which are turnable around the longitudinal axis of said blades, and a wind turbine hub connecting said at least two wind turbine blades with at least one shaft. Further, the wind turbine includes hydraulic means for actuating said at least two wind turbine blades, said hydraulic means being incorporated in said rotating means. The invention also relates to a hydraulic system, an air bleed system and a method of controlling at least two wind turbine blades.

Wind turbine, hydraulic system, air bleed system and method of controlling at least two wind turbine blades

A wind turbine with a rotor, a nacelle and a tower. The nacelle comprises a planetary gear () with a planetary holder (), on which the hub () of the rotor is rigidly secured, and which can be connected to the shaft of an electric generator. The planetary gear () comprises a ring gear () fixedly mounted on an engine frame () in the nacelle or on the member () rigidly connected to said frame. The planetary wheels () of the planetary gear can run around a centrally arranged sun wheel () while engaging the latter. The sun wheel is optionally connected to a parallel gear (). The planetary holder () is rotatably mounted in the ring gear () by means of at least two sets () of planetary twin wheels (). Each set of planetary twin wheels is mounted on a bogie shaft () on the planetary holder. Through an axially rearward collar () projecting beyond the ring gear, the planetary holder () is also rotatably arranged on the curved outer side () of the ring gear () by means of an outer radial-axial-roller bearing (). As a result, a wind turbine is obtained which is suited for generating very strong power and which is very compact and ensures a very advantageous transfer of the power at each planetary wheel.
