PURPOSE: An aerogenerator is provided to generate large torque with a small amount of wind and rotate the magnetic pole and armature of a generator in opposite directions by employing three rotary vanes having different lengths. CONSTITUTION: An aerogenerator comprises a first vane(10), a second vane(14), a third vane(16), a first power transmission mechanism, a second power transmission mechanism, and a generator. The first vane is installed on the leading end of a rotary shaft. The second vane is longer than the first vane, is installed on the rotary shaft with a housing(3) located between the first vane and the second vane, and rotates opposite to the first vane. The third vane is longer than the second vane, is installed behind the second vane on the rotary shaft, and rotates opposite to the second vane. The first power transmission mechanism transfers the rotational motion of the second vane to the armature of the generator. The second power transmission mechanism transfers the rotational motion of the third vane to the magnetic pole of the generator. The generator generates electricity by rotating the armature and the magnetic pole in opposite directions with the rotational motion delivered through the first and second power transmission mechanism. |
