Introduction If you want to make your own wind turbine, how about using your car's generator and charging system? I use the factory horn electric fan blades. Automotive generators make wind turbines,

If you want to make your own wind turbine, how about using your car's generator and charging sy

To make a wind turbine from a car generator, the speed of 120 rpm is far from sufficient. You need to reach at least 800 to 1000 rpm to produce electricity. If you do not modify the generator and want to use it as a wind turbine, you need to increase the transmission ratio of the transmission gear. The higher it is, the better. , because you are the car's charging system and the system will automatically adjust. Yes, there will be no problem. You want the car engine to be running at least several thousand rpm at high speed and the generator will have no problems. The only thing you worry about is whether the wind power system, bracket and transmission assembly you made can withstand the test under strong winds, haha.

Why are wind turbine blades designed to be wider

Not necessarily, the power of the veThe torque is equal to the product of torque and angular velocity, so large torque does not necessarily have large power output.

The most typical example is the Dutch wind turbine and the now common three-blade wind turbine, if both are the same size, under certain wind speed conditions, the Dutch wind turbine has much larger torque, but the rotation speed is very slow, so it cannot be used for electricity generation

"The width of the blades, the number of blades and the speed are inversely proportional. It is undeniable that compared to narrow blades, wide blades produce greater resistance when rotating. However, at the same time, the wind pressure on the windward surface of wide blades is also higher than that of narrow blades. The reason why the wind wheel rotates is that the positive wind pressure on the blades is greater than theresistance on the blades during the rotation of the wind wheel. Pressure and resistance follow physics. Pressure equals pressure times pressure. surface, that is to say F=P*S (F, the pressure on the blade; P, the pressure on the blade per unit area; S, the effective surface of the blade under pressure). Since the wind pressure remains unchanged under the same conditions, the force exerted on the blade is related to the effective pressure area of ​​the blade. Therefore, it can be seen that under the same conditions, a wind rotor with wide blades is easier to receive and absorb wind energy than a wind rotor with narrow blades. The wind rotor gets more energy and the wind rotor spins more smoothly and has. a higher speed. In the same way, a wind turbine under the same conditions will obtain different wind energy with different number of blades, more wind energy will be obtained, the wind turbine will beeasier to start and the speed of the wind turbine will be greater. will be higher.
