Parameters of power generation: Power generation mode: DC Output voltage: 0,01-5,5 V Output Current: 0,01-100mA Rated speed: 100-6000 rpm Generator size Engine diameter: 24,5 mm Engine height: 34,2 mm (including front and rear bearing sleeves) Output shaft diameter: 2,0 mm Output shaft length: 13,5 mm Installed fan blade size: total diameter 100mm total height 60mm Fan blade diameter: 1,95 mm (can be tightly fitted to 2 mm shaft) Features of Vertical Wind Turbine: No matter which direction the wind blows from, it can be powered by the wind. Compared to a traditional horizontal wind turbine, the advantage is that it can be started with the wind. The disadvantage is that in strong winds, the efekt of power generation is slightly smaller than that of a horizontal generator. This model is small in size and ma a good efekt. It is a very good teaching tool for wind energy demonstration. It can also be used to make various small technological productions, modeling, etc. The package includes: 1 x generator wind
