How to connect a small battery to Mr. Fu's motor-fan-generator?

1. First, you need to determine the positive and negative poles of the small battery to be connected. The positive pole of the battery is convex, while the negative pole is flat.

2. Next, you need to find the positive and negative poles of Mr. Fu's fan motor. They are found on the generator wires. A wire is connected to the positive terminal of the motor. the other wire connects to the negative terminal of the motor.

3. Finally, use a wire or other suitable connector to connect the positive terminal of the battery to the positive terminal of the generator, and connect the negative terminal of the battery to the negative terminal of the generator, making sure the connection is firm to avoid a power interruption or a short circuit.

How to make a generator from a fan?

This so-called wind power plant is actually the “big windmill” that everyone knows. A motor is installed in the windmill. LoWhen the desert wind blows, it pushes the blades of the wind power plant (so these blades must be both light and strong) to spin, providing heat to the engine and then converting the heat. This is the whole process of producing wind energy. But the construction of this wind power plant also requires certain skills. The windmill blades cannot be too heavy, otherwise the wind may not be able to push the windmill. At the same time, the blades must be very strong, otherwise the sand will mix. with the wind in the desert, it will definitely break the leaves. At the same time, the part below the wind power plant must also be very strong, because we all know that the power of sandstorms is very enormous. If the wind power plant is not well constructed, it may be blown away by the wind. Sandstorm.

Therefore, we must not only discover energy,but also protect it and create a magnificent “global village” with our hands!

How to make your own wind turbine

In fact, if you spin the rotor at a certain speed, there will be electricity (induced current).

You can also disassemble the motor of the electric toy car, connect a small bulb to the positive and negative terminals of the motor, then turn the motor rotor hard, you will find that the light turns on.

If you are making a small generator (providing a set of small LED lights), I suggest using a DC motor fan motor, as it is simpler (the direction of the generated current does not will not change).

But to make a motor, you need power to turn the generator, so you have to find another motor or machine to drive the generator, so it's quite inconvenient. You might as well find a transformer to convert the currentalternating current of 220 V at the nominal voltage of the LED.

If you just want to make some small inventions as a personal hobby, just follow what I said above.

Actually, I've done something similar before out of curiosity, but at that time I was using the motor of a four-wheel drive toy. The above is just my personal experience, I hope it is helpful to you!

I wish you success!

Asking for help, I want to make a wind turbine to charge the external battery

A windmill, a motor, a small wind turbine, a light bulb, wires

In In the process of converting wind energy into mechanical energy ~

The mechanical power should be as high as possible~

The weight of the windmill blades must be low~

There is also a difference in the number of blades you choose~

This must be done by yourself Test~

A transmission speed change device is also necessary~

Since the speed of the windmill will not vary be too high~

A speed change device is necessary to accelerate the speed~

Just use a gearbox~

The step of converting mechanical energy into electrical energy energy~

Since the voltage required by lz is not large~

Use ordinary magnetic poles A fixed generator will be enough~

The output voltage will be unstable~

If necessary , add a voltage stabilizing circuit at the output end~

Use a 9V-12V toy DC motor, coupled with a wind propeller (actually a brushed DC fan), can in turn be used as a direct current wind generator.

Connect the two motor electrodes to a bridge rectifier (avoid reverse connection of positive and negative) and connect the output to a diodee Zener of 5.6 V and an electrolytic capacitor of 1000 mfd/10 WV. This way you can charge the power bank.

For safety reasons, a 1000 microhenry 1A inductor can be connected in series at the output end to prevent overvoltage from damaging the power bank chip.

It's good to have an experiment. Unless the wind is strong, the charging effect may not be ideal.
