I don't understand what you said about water breaking down. But I know how to use this little motor to generate electricity. I used to drive this kind of four-wheel drive vehicle and did experiments to prove that it could indeed generate electricity. Experimental steps: First, there are two identical small motors. Place the two motors shaft by axis, then attach the tops of the two shafts, i.e. let the other motor spin it, then go from there. the engine to produce electricity. When the two wires connected above are connected to a small bulb, you can see that the small bulb is glowing, but the light is unstable because there is no rectified current. What I'm talking about is okay as an entertainment experience, but it doesn't make much sense if you want to use it to generate electricity. But I hope it helps youwas useful and I wish the author success. . .
It can be completed more quickly by hand.
Find a motor that was removed from an electric toy using a 6V battery, then find an old mechanical alarm clock, disassemble the movement and remove the pendulum, second hand gear, gear alarm and spring. . Find a suitable gear inside based on the required speed (the minute hand or gear one step slower than the minute hand will do it). Take it out and try to put it on the motor shaft, then design a suitable bracket to connect it). the motor gear to that when removed. Re-engage the mesh gear and remove any gears that are faster than this gear.
Make a rocker and insert it on the winding shaft to shake it so that the motor can rotate at high speed. Use a multimeter with a DC voltage of 10 V to measure the polarity and voltage of the electricity emitted. It should be around 5V to 6V. Depending on the charging current of the mobile phone, a resistor can be connected in series to charge the mobile phone.
The fixed bracket is randomly designed for easy portability and manual start.
I made one for outdoor sports. It is mainly used to prevent the mobile phone from running out of power and losing contact with the outside world in places without power supply. The output is connected to the USB interface. It's a shame that the voltage is a little lower. Some cell phones can be charged, but others cannot.
