The weapon tycoon who traveled to Daqin

Naofumi looked at many inventions and recorded them. These inventions all need protection.

After checking these, Naofumi is going to do some experiments. The laboratory chemistry started yesterday. This time it is physics. The physics experiment is electricity. Naofumi believes that the sooner electricity is generated, the better. Moreover, it is needed in many places. Especially processing machine tools.

On the other hand, steam power is currently used. But if electricity is used, the situation may be greatly improved.

Today's inventions cannot stay at the enlightenment stage; they should take a big step forward.

Generator and electric motor. The first thing to do is these two. There is no problem with the generator, the problem is the electric motor. With electricity, batteries will also come out, but sulfuric acid has just started. The chemical foundation is extremely weak.

Modern disciplines develop very fast, and they must cross-development and restrict each other. If one field stagnates, it is impossible to make a difference in another field. For example, in chemistry, the glass industry cannot develop due to the backward acquisition process of sodium carbonate.

There is also the production of sulfuric acid, which makes the processing technology lack a process. There is also the aspect of electricity. With electricity, there is a lack of necessary storage equipment. The application of electricity is still in the laboratory stage, one link after another, one link within another.

A generator is usually composed of a stator, a rotor, a generator, an end cover, a bearing, and other components. The stator is composed of a stator core, a wire wrap winding, a frame, and other structural parts that fix these parts.

The rotor is composed of rotor core (or magnetic pole, magnetic yoke) winding, retaining ring, center ring, slip ring, fan and rotating shaft.

The stator and rotor of the generator are connected and assembled by the bearings and end covers, so that the rotor can rotate in the stator and perform the motion of cutting the magnetic lines of force, thus generating an induced electric potential, which is led out through the terminals and connected in the circuit to generate current.

But its working principle is based on the law of electromagnetic induction and the law of electromagnetic force. The materials Naofumi needs to collect include a large number of copper wires, iron cores, and what else. Oh, and magnets. The magnets used today are all natural magnets.

, most of these magnets are formed by the high voltage that passes through instantly during thunder in the wild, or they are some meteorites. Naofumi opened the box of magnets he collected.

"Oh, my God." Naofumi went a little crazy. The magnets he collected came in all kinds of shapes. They were all kinds of strange. I didn't know that he had a quirk of collecting stones, so he sent them to me directly without any processing. Naofumi also said

These natural magnets must be roughly processed according to your own ideas. Naofumi called someone to process these natural magnets like blocks.

However, Naofumi also realized a problem, that is, it is obviously not possible to rely solely on natural magnets. Because, with the acceleration of industry, it is impossible for such large-scale natural magnets to exist. If resources are exhausted, my God

Ah, there is a good show to watch. Everything has to stop.

But humans always have a way, that is, artificial magnets. In 1822, French physicists Arago and Lussac discovered that when current passes through a winding with iron in it, it can magnetize the iron in the winding.

In 1823, Sturgeon also conducted a similar experiment: he wound 18 turns of bare copper wire on a U-shaped iron rod that was not a magnet rod. When the copper wire was connected to the voltaic battery, it wound around

U-shaped iron rod

The copper coil on the iron rod generates a dense magnetic field, thus turning the U-shaped iron rod into an "electromagnet." The magnetic energy on this electromagnet is many times larger than that of a permanent magnet, and it can absorb objects 20 times heavier than it.

times the amount of iron, and when the power is cut off, the U-shaped iron rod cannot absorb any iron and becomes an ordinary iron rod again. Sturgeon's invention of the electromagnet allowed people to see the conversion of electrical energy into magnetic energy.

bright future.

In 1829, the American electrician Henry made some innovations in the Sturgeon electromagnet device. Insulated wires replaced bare copper wires, so there was no need to worry about being short-circuited by the copper wires being too close. Since the wires had an insulating layer, they could be circled

The enclosures are tightly wound together, and because the coils are denser, the

The stronger the magnetic field generated, this greatly improved the ability to convert electrical energy into magnetic energy. By 1831, Henry trial-produced a newer electromagnet. Although it was not large in size, it could pick up 1 ton.

The invention of the iron block and the electromagnet also greatly improved the power of the generator.

This period of history is familiar to Shangwen. Because if the current society has a power outage for one minute, human society will almost come to a standstill. If the power goes out for a day, it will be a disaster. Human beings can endure it better than without water and food.

Naofumi said as he picked up his notebook and started recording. Then he handed it over to the craftsmen, and then began to separate the first batch of electrical talents from the craftsmen. Now the entire arsenal has almost become a giant laboratory. There are inventions and craftsmen everywhere.

While busy with production, start to pay attention to observation in order to invent something. This is a good phenomenon.

"General, please." A craftsman's voice came. Naofumi buried his head in writing something.

Wang Jian saw Shang Wen immersed in writing something, and he understood Shang Wen's character. This is when thinking is most active. It is also when most inspiration appears. At this time, even King Qin had to wait carefully aside, not even daring to make a sound.

issue.

"It's General Wang. I'm sorry, I'm sorry." Naofumi said with his head buried in the air.

"Sit anywhere you want." Naofumi still buried his head in writing.

"By the way, what's the matter with General Wang?" Naofumi asked. As he spoke, he began to put down the pencil in his hand. Then he tore it off and handed it to the craftsman who was serving food and water.

"Mr. Qin is still so busy. I came here because of this technology. I checked out the Musketeers. The impact was too great," Wang Jian said.

"Oh. If this is the case, the impact on the general is not enough. Come on." Shang Wen said, taking Wang Jian's hand and leaving the room.

Shang Wen took Wang Jian to various workshops of the arsenal.

Wang Jian was still eye-opening. The first thing he saw was the hydraulic press. The huge hydraulic press could press a piece of red-hot iron into a thin piece of iron. This was the first time Wang Jian had seen such a powerful force. Shang Wen was standing by.

Explain to Wang Jian that this is based on Pascal's law. Then simply draw.

Then there are machine tools, which produce a large number of gun barrels. The speed of gun barrels has been greatly accelerated. Then there are four-wheeled carriages, which are comparable to trucks and have more than double the load capacity of ox-carts. And

It is fast. Especially on the highway, it can travel quickly. There are also bicycles. If bicycles were originally made

If it is useless, then the usefulness of bicycles is beginning to show up now. The main reason is the huge change in combat weapons. In the past, combat weapons required close combat and relied on the fighting skills of soldiers, but now it is very different. Bicycles are a brand new

The mobility method has begun to have a new market. The military.
