It's easier to use an off-the-shelf motor. How did your teacher test it, whether to use natural wind or a fan to start the generator? It's hard to tell when it comes to natural wind. The wind must be strong enough to start the generator. The stronger the wind, the faster the motor spins and the more electricity it generates. The same is true for motors and blades. But the proportions must be appropriate, not a big motor with a small maple leaf. The blades can be those of a fan, and the motor must be one with magnets. Do the experiment slowly. When the wind speed and light bulb remain unchanged, the brighter the light, the higher the voltage.
How to make your own wind turbine
A DC generator, a rotating impeller, a pole to stand the wind turbine on, a length of wire, and an inverter to generate The direct current is converted into alternating current, and a battery is used to store the excess electricity. The cost will not be very low. There is no guarantee of reliability if you do it yourself. This is related to your craftsmanship. If it is for fun, you can try it. If it is for use, Then buy ready-made ones
What is the principle of electricity? What materials are needed to make a homemade wind turbine? Please describe in detail,
A windmill, motor, small wind turbine, light bulb, wires
In the process of converting wind energy into mechanical energy ~
Requires mechanical power As high as possible~
The weight of the windmill blades should be small~
It also makes a difference depending on how many blades you choose~
This needs to be tested by yourself~
You also need a transmission gearbox~
Since the speed of the windmill will not be too high~
You need to use a gearbox to speed up the speed~
Just use a gearbox
The step of converting mechanical energy into electrical energy~
Since the voltage required by lz is not large~
Just use a general fixed-pole generator~
The voltage output in this way is unstable~
If necessary, add a voltage stabilizing circuit to the output~
Principle: The principle of wind power generation is very simple. Simple, the simplest wind turbine can be composed of an impeller and a generator, as shown in the figure. The kinetic energy of the air flow acts on the impeller, converting the kinetic energy into mechanical energy,
thus driving the impeller to rotate. If the rotating shaft of the impeller is connected to the rotating shaft of the generator, the generator will be driven to generate electricity. The paper windmill that children play with is the prototype of a wind turbine. A tiny generator can be installed on its axis to generate electricity. Equipment: Small wind turbine grid-connected power generation systems generally consist of small wind turbines, rectifiers, unloading loads, grid-connected inverters and other components
