WIND TURBINE GENERATOR |
摘要 |
PROBLEM TO BE SOLVED: To reduce the size and weight of a driving apparatus for making torque characteristics of a wind turbine generator variable. SOLUTION: The wind turbine generator includes a rotating rotor 1 that is rotated by the rotation of a wind turbine 400, and has multiple magnets 3 disposed at predetermined intervals so that they encircle its own rotation center 1c; multiple cores 5 disposed at predetermined intervals so that they are movable in the direction of the extension of the center line of the rotation center 1c and they encircle the rotation center 1c; multiple generating coils 6 that are provided in correspondence with the individual cores 5 and generate power by a change accompanied by the rotation of the magnetic flux of the magnets 3 taking the corresponding cores as magnetic paths; and the driving apparatus 9 that moves the individual cores 5 in the direction of the extension of the center line 1c.
