The current environmental pollution is still quite serious, and it has become the mainstream now. Everything is moving towards this direction! In the past, we used to generate electricity by burning coal, but this would pollute the atmosphere. Therefore, wind turbines were invented. Today, we are going to make a simple wind turbine, using very common materials. A wind turbine is a power equipment that converts wind energy into mechanical power, which then rotates the rotor to ultimately output alternating current. The working principle of a wind turbine is quite simple. The wind wheel rotates under the action of the wind, converting the kinetic energy of the wind into mechanical energy of the windwheel shaft, and the generator rotates and generates electricity under the drive of the windwheel shaft. Broadly speaking, wind energy is also solar energy, so it can also be said that a wind turbine is a kind of thermal energy generator that uses the sun as a heat source and the atmosphere as the working medium.

Wind turbines convert wind energy into mechanical power, which in turn rotates the rotor to generate electricity. Wind turbines are typically composed of several components, including the windwheel, generator (and associated equipment), yaw mechanism (tail fin), tower, speed limit safety mechanisms, and energy storage devices.
The working principle of a wind turbine is relatively simple. The wind wheel rotates under the action of the wind, converting the kinetic energy of the wind into mechanical energy of the wind wheel shaft. The generator rotates and generates electricity under the drive of the wind wheel shaft. Broadly speaking, wind energy is also solar energy, so it can also be said that a wind turbine is a kind of thermal energy generator that uses the sun as a heat source and the atmosphere as the working medium.

For many centuries, windmills, like water-powered machinery, have played an important role as a substitute for human and animal power, contributing significantly to the development of productivity. The widespread application of modern electrical and mechanical power, as well as the discovery of oil fields in the Middle East in the 1950s, led to a slowdown in the development of windmills.

In the early 1970s, due to the "oil crisis," there was a problem of energy shortage. People realized the instability and limitations of the supply of conventional mineral energy, so seeking clean and renewable energy sources has become an important topic in the modern world. Wind energy, as a clean and renewable natural energy, has once again attracted people's attention.

Wind power is converted into mechanical energy, and then mechanical energy is converted into electrical energy. In a broad sense, it is a heat engine that uses the sun as a heat source and the atmosphere as a working medium for heat energy. Wind power makes use of natural energy. It is much better than diesel generation. However, if used as an emergency, it is still not as good as diesel generators. Wind power should not be considered as a backup power source, but it can be used on a long-term basis.

The principle of wind power generation is to use the wind to drive the wind turbine blades to rotate, and then through the speed-increasing machine to increase the rotation speed, to cause the generator to generate electricity. According to the current technology of wind turbines, it can start generating electricity when the wind speed is about 3 meters per second (the degree of gentle wind).

Wind power is forming a surge around the world, as it does not face fuel issues and does not produce radiation or air pollution.

Wind power is very popular in Finland, Denmark, and other countries; our country also actively promotes it in the western region. Small wind power generation systems are very efficient, but they are not composed of just one generator head, but rather a small system with certain technological content: wind power generator + charger + digital inverter. The wind power generator is composed of the nose, the rotor, the tail, and the blades. Each part is very important, and the functions of each part are as follows: the blades are used to accept the wind and convert it into electricity through the nose; the tail allows the blades to always face the direction of the wind to obtain large wind energy; the rotor can make the nose rotate flexibly to realize the function of adjusting the direction of the tail; the rotor of the nose is a permanent magnet, and the stator winding cuts the magnetic force line to generate electricity.

Wind turbines generate variable AC electricity ranging from 13 to 25V due to the instability of wind speed. This AC electricity must be rectified by a charger before being used to charge a battery. The generated electrical energy is then converted into chemical energy in the battery. Subsequently, an inverter with a protective circuit is used to convert the chemical energy in the battery back into 220V AC electricity to ensure stable use.

Mechanical connection and power transmission: The horizontal shaft fan blades are connected through a gearbox and its high-speed shaft with an elastic coupling, which transfers torque to the drive shaft of the generator. This coupling should have good characteristics of absorbing damping and vibration, which shows as absorbing appropriate amounts of radial, axial, and certain angles of offset, and the coupler can prevent overloading of the mechanical device. Another type of direct-drive fan blades are directly connected to the motor without going through a gearbox. The type of fan motor is "fan motor type".

  Before assembling, please check if the circuit is unblocked and all the components are complete. Ensure that all contact points are in good contact. During the assembly process, be careful not to get glue on your clothes or skin. Keep the parts out of reach of younger siblings to prevent them from swallowing them by mistake! Do not play with them on your head, to avoid the model falling and injuring you!
