PROBLEM TO BE SOLVED: To provide a direct-coupled type micro-wind power generator which does not use an acceleration gear which can generate electrical power sufficient for practical use by solving the problem of the micro-wind power generator being unable to generate power sufficient for practical use, because the rotation al speed of a windmill is normally low for weak wind (wind speed is 3 m or less). SOLUTION: A rotating shaft of the wind power generator has a double structure for rotating a rotor with a center shaft and rotating an armature with an external shaft. Although windmill blades are mounted at intervals to the center shaft and external shaft, when the windmill blades receive wind from the same direction, the blades are rotated in directions which are opposite to each other. |
