Description _x000D_ _x000D_ This vertical wind turbine model, whether blown from the wind direction, can be powered by wind. The advantage is that it can be micro-started. The disadvantage is that the power generation effect is higher than that of the horizontal generator when the wind is high. _x000D_ _x000D_ Features _x000D_ _x000D_ - Color: Yellow. _x000D_ - Material: ABS. _x000D_ - Size: 7.00X6.00X6.00cm/2.75X2.36X2.36 inch. _x000D_ - Output voltage: 0.01-5.5V. _x000D_ - Output current: 0.01-100mA. _x000D_ - Rated rotate speeds: 100-6000RPM. _x000D_ - Good choice for teaching physical DC wind power generation principle. _x000D_ - As the model is packaged by completely accessory sets ,you need to assemble by yourself ,just enjoy the DIY fun . _x000D_ - Advanced design, high utilization rate of wind energy, no matter where the wind blows, it can be powered by the wind. _x000D_ - Small size, no noise, good demonstration effect, is a very good demonstration tool for DC wind power generation and DIY science education experiment. _x000D_ - Great teaching tool to develop childrens hands-on ability and develop interests._x000D_ _x000D_ _x000D_ 1 x motor_x000D_ 4 x fan blades_x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_
