Make your own small generator (be as specific as possible)

The simplest method:

Materials: toy electric fan, household electric fan

Production steps:

Open the electric fan toy, lead disconnect the wires from its motor. Connect the voltmeter.

Turn on the household electric fan and let it run. Then place the toy electric fan next to the household electric fan and let it spin. The toy electric fan will generate electricity. The voltage emitted is proportional to the speed of rotation.

Small handmade generator

I am in my second year of college. I also participated in small inventions in this science and technology festival. I will tell you a very simple one. Need a magnet, battery and copper wire? Place the magnet on a horizontal table, place the positive terminal of the battery on the magnet, then place the M-shaped copper wire on the negative. borne of the battery, and then the copper wire will turn? Is it easy to use? Doesn't that cost too much? Do you remember to give me the best answer (it's not copied from the Internet)

Just use an electric fan to modify it. Users can use an electric fan motor with a power of about 50W and combine it with an industrial electric fan blade (power of about 2~300W) to make a wind turbine. The effect is good.

You need to make the bracket yourself and it can rotate, then make the rear fin for navigation, so that everything is together. longer so it won't break even if wrapped around the rack more than 10 times. However, you need to unwind the tangled wires every day, but you can keep the electrical slip ring, the technology is relatively simple.

The output end is fixed with a capacitor to help crevert the voltage, and a low-power overcurrent switch or fuse is installed to prevent the generator from overloading

Such a generator also has disadvantages, i.e., the frequency changes with the output power and voltage fluctuation is relatively large. It is easy to burn the bulb. It can be used for grinding and charging. The lamp will have to be converted to direct current, and the price will be high. more expensive.

Grid-connected operation can solve such problems, but it will also lead to new problems. When the wind power is insufficient, the wind turbine turns into an electric fan and it is easy to burn the motor. It is better to cut off the start capacitor or It is also possible to change the direction and install the fan blades in another direction, but low winds will still consume some energy.rgie. Installing a power relay can solve the power backflow problem, but the price of the system will increase and the gain will exceed the loss.

Note that the generator made this way does not have overspeed protection and will be more dangerous on windy days.
