Introduction I bought a small generator on Taobao to make a wind turbine, but the magnetic resistance is a bit big and it is difficult to start. The blade diameter is 750 mm. Does anyone have experience? Please tell me I am engaged in wind energy. The main reason is n

I bought a small generator on Taobao to make a wind turbine, but the magnetic resistance is a bit bi

I work in wind energy. The main reason is not that you have a large magnetic resistance, but that you chose a larger motor. According to the wind power formula

Theoretically, the generator power =. 0.593*0.5pAv^3* c

Limit wind energy conversion efficiency: 0.593

p: Air density

A: swept area

v: wind speed

The ultimate efficiency of our large-scale wind turbines is only about 0.43.

But if you make this blade it looks even lower in the photo. if your conversion efficiency is the highest, then calculate that you are 6 meters away. The wind power is 28 watts, that is to say it is only 174 watts in an 11 meter wind. You can find the wind 11 meters on the ground. , so in a 6 or 7 meter wind, you can't even blow up the windmill, you can only increase the blades. Only the area can bee resolved.
