What should I do if I start with a small manual generator?

A generator, including some related devices, parts, and parts required for power generation in multiple groups such as mechanical watches, mechanical alarm clocks, etc.

Working principle: Using the working principle of mechanical watches, mechanical alarm clocks, etc., the balance gear in the escapement (which can control its movement speed) drives the conductor to do the cutting magnetic induction line movement and generate electricity.

By using the principle of lever to increase the length of the lever (string), you can wind the spring with a small amount of force (apply energy), and then wind the spring (apply energy) ...... when the energy of the spring is used upThe length, quality, and style of the mainspring ......Be appropriate.

It can be used as a manual charger (equipment) and a generator (equipment). Small or large ones are fine.

The value of the current generated is proportional to the total energy of the mainspring; The duration of power generation is inversely proportional to the rotational speed of the balance gear; The strength of the current generated is directly proportional to the speed of the balance gear.

The embodiment can be manual or automatic (the number of parts required for power generation such as magnets can be increased, so that the power generation of the generator is greater than the current value of the work that allows it to do work).

A simple way is to use a permanent magnet DC motor as a generator, install an upper wind wheel drive, because it is impossible to have a high speed, you can choose a DC motor with high withstand voltage, so that even if it is low, you can get a higher voltage, you can choose a low-voltage power supply and you can stabilize the voltage to charge the battery, you can choose a lithium battery for mobile phones and you want to stabilize the voltage to no more than that, you can connect a silicon diode in series to illuminate the high-brightness light-emitting diode, this kind of battery has no memory and can be used with confidence, You can make the mechanical part according to your own needs.

Have you watched "Mythology"? In it, Ogawa made a generator, and to make a generator, you must first know the principle, and then find the magnet, and the wire......Anyway, it seems to be quite complicated.

Self-guessing hand-cranked generator.

Materials: a small toy motor, a pulley with a diameter equal to 20 cm, a round pencil head, latex, a rubber band, a small light bulb, and a wooden board.

Method: 1) Fix the small motor on a wooden board.

2) Take a 6 mm long pencil barrel, remove the lead core, and use a triangle steel to frustrate into a belt pulley to make a small pulley.

3) Glue the small pulley to the small motor shaft with latex.

4) Make a large pulley with a diameter of 20 cm from two layers of plywood.

5) Place the large pulley on the wooden board and install the crank handle.

6) Put the rubber band on the small pulley and the large pulley.

7) Connect the small bulb to the two terminal points of the small motor.

8) Quickly shake the big pulley crank to make the small motor generate electricity and light up the small bulb.

Note: 1) Choose a motor with a strong magnetic force at the magnetic pole. By twisting the small motor shaft with your fingers, you can feel the magnetic force of the magnetic poles.

2) The faster the shaking handle, the stronger the electricity emitted, and the brighter the small bulb, the better the experimental effect.
