That night, Li Tai dropped his beloved teapot, Li Ke snubbed his beloved woman, Fang Yizhi was beaten by his father, and Li Chengqian ...... I slept very comfortably.

This Tang prince has been feeling that he is growing meat recently, maybe this is the so-called wide heart and body fat, of course, it may also be the reason for obesity.

Qin Jisheng, the new foreign minister of the Yamato Kingdom, completed the tasks assigned by Li You and Yang Tian, and he was very honest in the post house every day and did not dare to go out.

Although the people of the Tang Dynasty outside were friendly to him, in order not to cause more trouble, he still tried his best to restrain his subordinates.

Curiosity will kill the cat, Qin Jisheng has been constantly reminding himself that if the prince of the Tang Dynasty wants him to see something, someone will naturally take him to see it, and if he doesn't want him to see it, it will be in vain.

And as it turned out, his guess was right, because there was a disobedient guy who went out and never came back, and later someone saw his body in the moat, and then was sent back by the officials of Honglu Temple.

……

The Research Agency, oh, now it's called the Tang Academy of Sciences.

Li Chengqian has been soaking here for five days and five nights day and night, directing craftsmen to draw out countless copper wires of thickness and thickness by drawing wires.

Then these freshly baked copper wires will be slowly cooled and then soaked in the rubber liquid, and when they are taken out again, there is already a layer of gum on the outside.

Yes, everyone is not wrong, Li Chengqian is making wires.

Xiao Li has really had enough of this kind of day of burning candles every night, anyway, now that the technology of the steam engine is almost mature, it is time to put forward the concept of electricity.

Although he doesn't have much professional knowledge, he still knows the concepts of stator, rotor, carbon brush, winding, and so on.

After all, I studied some in high school, and I secretly took a few courses in electrical power when I was in college.

With these basic knowledge, coupled with the huge financial resources and manpower at his disposal, even if it cannot be successful, it is still possible to conduct an experiment.

Of course, the more important point is that Xiao Wu's girl is too tormenting, since she became the queen of Yamato, she ran to the palace every day, and then went to the palace with Changle's girl, and tossed a good miasma of the East Palace.

So Xiao Li simply came out of sight and out of mind, Lao Tzu tinkered with his own things, and the East Palace was handed over to those girls to toss.

After a moment of distraction, Li Chengqian shook his head, and said to Tang Shanzhi, who was confused and didn't know what to do next: "You go and build a batch of convex thin iron sheets and come back, remember, it needs multiples of three." ”

"Do what?" Tang Shanzhi has been tossed by Li Chengqian in the past few days, and he has no idea what Li Chengqian is talking about.

"You don't care about this, you don't understand what you say, you can get it if you want to, and you don't need to go into battle in person anyway." Li Chengqian angrily threw him a piece of paper: "It's probably like this, you just do it, you can do it according to the size or something, it's best to get some big and small." ”

Tang Shanzhi is a physical idiot, and he just wants to know everything, if you tell him that gravity exists, he can give you a relationship between men and women, and Li Chengqian doesn't have any idea of giving him popular science for this kind of person.

……

The iron core and thin copper wire are wound together in a fixed form little by little, which can be called a winding, and the uneven iron sheet is the iron core, and these two things are combined together in a certain way, and an iron rod is inserted in the middle is a simple rotor winding.

And if the uneven iron sheet is circled into a circle and then matched with the winding, then this is called a stator winding.

Combining the two things together, it is a simple generator main structure.

Of course, what the author says here is simple, but in fact, whether it is a stator or a rotor, there is a certain standard for the number of core grooves in them, and there is also a certain standard for the angles of separation, but in general, it is roughly a multiple of one hundred and twenty.

Back to the book, Li Chengqian's toss, half a month has passed, and the prince, who was originally slightly blessed, has returned to the standard weight again, but he is much sloppy compared to before.

But I have to say that the craftsmen of Datang are really powerful, and without any theoretical basis, they actually made a small three-phase generator (long image).

However, when Li Chengqian connected this thing to the steam engine and the steam engine provided power to make it spin, he did not have any tools in his hand to test whether this thing was successful or not.

It's an embarrassing question, seeing the generator make a 'buzzing' sound, but I don't know if it's good or not, after all, electricity is something that can't be seen or touched, and it is impossible to know whether it is successful or not with the naked eye.

But who is Li Chengqian? Cheng Fairy's mouth is a character with a ghost head and toad eyes.

How could such a person be so simple to ask.

So Li Chengqian patted Tang Shanzhi beside him: "Shanzhi, go and help me bring the thread on the ground." ”

Following the direction of Li Chengqian's finger, Tang Shanzhi really saw a copper wire.

Poor little Tang didn't know the danger because of his lack of physical knowledge, so he walked over with a hum, bent over, stretched out his hand to ......, and then only heard a 'pop' sound, plus a sheep voice that made the listener cry: "Ah......"

"It worked, I made it!" Looking at Xiao Tang, who was trembling with electricity, Li Chengqian clenched his fist fiercely, and then picked up a wooden stick on the ground and hit Xiao Tang's hand holding the copper wire.

Why is there a stick on the ground? It's weird! After beating Xiao Tang, Li Chengqian thought so.

But these don't matter anymore, the important thing is that the generator succeeded, and although there is a lot of fluke in it, it is undeniable that it is indeed working.

How much current does a generator have? How much voltage is there? Li Chengqian didn't know any of this.

But what does it matter, Xiao Tang was not electrocuted anyway, which is enough to show that the power of the generator will not be very large.

In other words, he doesn't need to make any step-down devices in the future, just use this generator directly.

And just when Li Chengqian was excitedly circling the ground, he heard a sheep's voice behind him: "Li, Cheng, Qian, you, big, master, of, I, with, you, fight, fight!" ”

Looking back, Li Chengqian realized that it was the tragic male Tang Shanzhi's classmate.

I saw Xiao Tang at this time, his hands and feet were trembling, his hair was standing on end, and saliva was flowing out of the corners of his mouth uncontrollably, which was completely a sign of a sheep epilepsy.

So, Li Chengqian shouted decisively: "Come on, the Tang Yuan is crazy, quickly tie him up!" ”
