Patent ID: 8026626

Claim:
A wind turbine arrangement, comprising: an axial flux alternator for generating electricity, said alternator comprising: a first coil disk; magnetic cores arranged on said first coil disk; a second magnetic disk arranged adjacent to said first coil disk; magnets arranged on said second magnetic disk; and rolling elements interposed between a surface of said first coil disk and a surface of said second magnetic disk that face each other, said rolling elements being arranged to maintain air gaps between a surface of said magnetic cores on said first coil disk and said magnets on said second magnetic disk, said alternator generating electricity from relative rotation between said first coil disk and said second magnetic disk during which said magnetic cores of said first coil disk and said magnets of said second magnetic disk are brought into and out of magnetic engagement with one another; and at least one wind turbine, at least one of said first coil disk and said second magnetic disk being rotatably coupled to a respective one of said at least one wind turbine to cause, when said at least one wind turbine is exposed to wind, the relative rotation between said first coil disk and said second magnetic disk.
