Abstract
A wind turbine that includes a rotor and a generator is described. The rotor includes a rotor hub that is rotatably mounted on a frame and one or more rotor blades. The generator includes a generator stator and a generator rotor with a carrying structure that carries magnetic or electromagnetic elements. One or more circumferentially arranged substantially axial protrusions that extend into the generator rotor carrying structure are attached to the rotor. Flexible couplings are arranged between one or more of the axial protrusions and the carrying structure.
Claims19
A wind turbine comprising:
- a rotor that includes a rotor hub and one or more rotor blades, the rotor hub being rotatably mounted on a frame;
- a generator that includes a generator stator and a generator rotor, the generator rotor including a carrying structure that carries magnetic or electromagnetic elements, the carrying structure comprising a plurality of struts;
- one or more circumferentially arranged substantially axial protrusions attached to the rotor, the axial protrusions extending into the generator rotor carrying structure so that an axial protrusion is disposed between and circumferentially spaced from adjacent struts;
- and
- one or more flexible couplings arranged between one or more of the axial protrusions and the adjacent struts.
A wind turbine comprising:
- a rotor that includes a rotor hub and one or more rotor blades, the rotor hub being rotatably mounted on a frame;
- a generator that includes a generator stator and a generator rotor, the generator rotor including a carrying structure that carries magnetic or electromagnetic elements, the carrying structure comprising substantially radial struts,
- one or more circumferentially arranged substantially axial protrusions attached to the rotor, and
- a plurality of couplings between the axial protrusions and a plurality of the substantially radial struts, wherein
- each of the couplings comprises a first flexible element arranged between a first of the axial protrusions and one of the radial struts, and a second flexible element arranged between a second of the axial protrusions and another of the radial struts and wherein
- each of the flexible elements comprises a hydraulic chamber and
- the hydraulic chambers of the first flexible elements are connected to a first hydraulic circuit, and
- the hydraulic chambers of the second flexible elements are connected to a second hydraulic circuit.
