Simple generator can be made into wind power. The cost is less than 10 yuan. Buy a VCD spindle motor at a component store or a place where DVD players are repaired (not a DVD one. The rotation speed is too high and the power generation is not good). The purchase price of the motor does not exceed 3 yuan, and it should be completed within 10 yuan.
After buying the spindle motor, fix the fan blades on its turntable. You can make your own wind leaves from cans. But it must be balanced and the angles are well-proportioned, and don't let it spin unevenly. In advance, connect a 100 ohm resistor to the motor lead and connect it in series with the high-brightness light-emitting diode to form a loop. Be sure to pay attention to the direction of rotation of the motor. Viewed from the turntable, when turning clockwise, the red line is the positive output terminal of the "generator". Adjust the blade angle to make it meet the conditions, and the wind turbine model is completed! It's from the Internet. Just modify it a little, stick the bottom of the can on the motor turntable, adjust the angle of the fan blades, and let the generator rotate clockwise under the wind.
How to make a vertical axis wind turbine
Fan principle, however, in order to have a certain strength, the closer to the root of the fan blade, the thicker it becomes. Made of fiberglass. The reinforcing ribs made of fiberglass are placed in the mold and then injected with resin to form. The small air leaf has a solid structure, and the large one has a hollow structure. The hollow part of the large fan blade is almost half a cylinder. It is not an exaggeration to say that it is based on the principle of an airfoil. The installation angle of the fan blades is generally adjustable. The wind turbine has a complete constant speed device, and a device that automatically brakes, then turns, and finally rotates again when the wind direction changes. Don't do your own research and development. If you want to make a finished product for sale, just buy one and then reverse engineer it. You can search for "Manufacturing Process of FRP Fan Blades".
1. The production of wind turbine requires a set of gears between the blade shaft and the generator shaft to change the rotation speed. Because the general fan shaft is relatively small and the rotation speed is slow.
2. It is necessary to install a large gear plate and then connect a small gear plate to the rotor shaft of the generator. The rotational speed is directly proportional to the gear size ratio. This part is the power unit. Wind turbines use kinetic energy to convert into electrical energy. ?
3. Generator part. There are finished products available for purchase in this part. The principle of a generator is exactly opposite to that of an electric motor. One is to convert electrical energy into power, and the other is to convert power into electrical energy.
4. Just buy a DC generator and install the blades. Solar generators are not easy to make by yourself. You can buy solar battery packs and assemble them to complete the vertical axis wind turbine.
