Abstract
A wind turbine is provided that minimizes the size of the drive train and nacelle while maintaining the power electronics and transformer at the top of the tower. The turbine includes a direct drive generator having an integrated disk brake positioned radially inside the stator while minimizing the potential for contamination. The turbine further includes a means for mounting a transformer below the nacelle within the tower.
Claims14
A wind turbine comprising:
- a nacelle;
- a blade rotor nosecone adjacent to said nacelle;
- a main shaft coupled to said nosecone and rotatably coupled to said nacelle;
- a generator coupled to said main shaft between said nacelle and said nosecone, wherein said generator includes a housing mounted to said nacelle, a generator rotor adjacent to said shaft, a stator positioned adjacent to and radially outward from said generator rotor, wherein said housing is disposed about said rotor and said stator;
- and,
- a brake coupled to said housing and said shaft, said brake being positioned radially inward from said stator.
