Keproving 2pcs Mini Vertical Wind Turbine Generator Model for Teaching Physical Power Generation Principle and DIY Science Education Experiment
Brand: Keproving

Output voltage: 0.01-5.5V
Output current: 0.01-100mA
Rated speed: 100-6000 r / min
Material :plastic and metal
Fan diameter:10cm/3.94in
Packaging List：2pcs
Note :
Whether it is used as wind power or hydropower, it must support enough power to the fan rotation fast , then the leds can be bright.To rotate the fan ,you can blow the wind by your mouth , hair dryer or a fan.
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

Good choice for teaching physical DC wind power generation principle.
As the model is packaged by completely accessory sets ,you need to assemble by yourself ,just enjoy the DIY fun .
Advanced design ,high utilization rate of wind energy, no matter where the wind blows ,it can be powered by the wind.
Small size, no noise,good demonstration effect, is a very good demonstration tool for DC wind power generation and DIY science education experiment.
Great teaching tool to develop children's hands-on ability and develop interests.<br> PS :Please note that it is just for testing and teaching use ,no actual use . In order to improve the display effect ,the turbine need to be powered by the fan or blow dryer on it at just the right angle instead of the natural wind .
