The production method is as follows:
1. Buy a generator with a power of 200w and a rated speed of around 400rpm;
2. some ABS pipes to cut it. The blades are then cut and polished properly as shown below:
3. Find a metal disc to connect the generator and the blades, which is the hub of the generator;< /p>
4. Drill holes on the blades and the metal discs. Pay attention to the best time to drill holes when drilling, for example:
5. You can find a hub cover for the wheel. hub to prevent the screws from being exposed to wind and sun. It can play the role of diversion
6. Make a stand to place the generator on, just some wood, then use some wire or iron sheets to place it on. fix the generator;
7. Make a connecting rod, preferably with a bearing; then make a tower with water pipes, and themwires connecting the generator can simply pass through this hole to finally connect the tower; generator and secure it with guyed steel cables to complete production.
Principle of the fan however, in order to have a certain solidity, the closer the fan blade is to the root, the thicker it becomes. Made of fiberglass. The fiberglass reinforcing ribs are placed in the mold then injected with resin to form. The small wind leaf has a solid structure and the large one has a hollow structure. The hollow part of the large blade is almost half a cylinder. It is no exaggeration to say that it is based on the principle of a sail. The installation angle of fan blades is generally adjustable. The wind turbine has a complete constant speed device and a device that automatically brakes, then turns and finally turns again when the wind direction changes. Don't make your own recresearch and development. If you want to make a finished product to sell, simply buy one and then reverse engineer it.
