Winding the coil, as simple as it sounds, is to wind the copper wire into a spiral shape to strengthen the magnetic field, and use the smallest space to achieve the highest magnetic field strength.

However, electromagnetic forming can effectively improve the formability of light alloys, and the coil structure is one of the key factors affecting the forming quality.

Therefore, the coil is not to go around a few times if you want to, but to determine the distribution of electromagnetic force and design a coil that adapts to it according to the needs of the deformed part of the workpiece.

That is to say, Cheng Yuan wants to wind a coil of a specific length and number of turns inside the bead, and it can be attached to the standard.

Fortunately, Cheng Yuan, who has artificial intelligence, does not have to do a little bit of calculation by himself like ordinary scientific researchers. Zero, who has a complete source of data, will soon be able to sort out all the data in context.

Cheng Yuan glanced at the data displayed on the computer and began to wind the coil!

The electric field force is proportional to the electric field strength, electrical displacement, and electrode area, and the magnetic field force is proportional to the magnetic field strength, magnetic induction intensity, and pole area. Therefore, the appropriate selection of electric or magnetic field parameters and geometric dimensions can obtain a certain bearing bearing capacity and stiffness.

The electrostatic attraction or magnetic attraction is inversely proportional to the square of the distance between objects, according to the Annshua theorem, this static system is static, in order to make the electromagnetic bearing work stably, it must be controlled by servo devices or adjusting circuit parameters.

Electromagnetic bearings are generally composed of radial bearings, thrust bearings, servo control loops, dampers, speed sensors or position sensors.

However, these questions are very simple things for Cheng Yuan.

Although he can't do the super-large-scale magnetic bearing cluster control in the movie, only five or six can still be controlled for the intelligence in his hands.

So this technical difficulty is countless notches lower than in the movie.

Winding a coil is a technical job. In particular, the winding part is still the inside of a bead that is only about two centimeters.

After giving the length and number of turns according to zero, Cheng Yuan began to cut the copper wire. The cut copper wire is then split in two and wound around two screwdrivers. The winding requirements are dense and there are no gaps, and this step alone took Cheng Yuan more than 40 minutes to complete.

Carefully squeeze the coil from the screwdriver to the inside of the ball, then apply the insulating varnish. At last. Cheng Yuan glued a careful magnet to each of the poles of the two semicircles, and the first step of the work was completed.

This is followed by the installation of the rotor and stator, which is much simpler than the first part, but the workload is not much less, but it has increased a lot.

Four small stators need to be installed in a bead, and the function of the stator is to rotate the magnetic field to ensure that the internal magnetic force will not leak out. The main function of the rotor is to be cut by the magnetic field line in the rotating magnetic field and then output current, which is the work of the entire electromagnetic bearing.

Small cores. The coil is wound, then welded with a small electric weld, mounted on the outer coil, and the four stators are installed in the four directions of southeast, south, north, and west, and then the center rotor is embedded into it.

A simple radial electromagnetic bearing ball is thus made.

Carefully putting down the small things he had spent nearly two hours making, Cheng Yuan began to test.

However, before the test, he also needed to make an external controller, and before installing it on Dabai's palm, Cheng Yuan could only make a separate controller to test. The making of the controller is simple. The two displacement annunciators and sensors are attached to a magnet wound around the coil and then energized.

If successful. The suction force inside the electromagnetic bead will hold the two magnets firmly, and then the ball will start to move itself at high speed.

Cheng Yuan only needs to control the size of the magnetic field through the controller to make the bead make different movements. Although they are all round and cannot be seen, as long as the beads can be turned, it proves that there are no mistakes in his workmanship.

"Zero, start testing. Scan the operating status of the internal electromagnetic field. ”

With everything ready, Cheng Yuan pressed the power-on switch!

"No problem, sir. ”

Zero replied softly.

Silently!

After Cheng Yuan turned on the switch, there was no current shuttle or special sound, only two magnets in the middle. The electromagnetic bead rotated suddenly, but the ball did not pop out or deviate from its position, and under the equal magnetic attraction on both sides, the ball was firmly fixed in the middle of the two magnets for rotation.

Seeing this scene, Cheng Yuan immediately smiled.

"It worked, zero. Cheng Yuan let out a soft sigh.

"Yes, sir. The internal magnetic field behaves intact, the stator behaves steadily, and there is no short circuit. Zero cooperated in a timely manner.

Hearing Zero's report, Cheng Yuan breathed a sigh of relief, then turned off the switch, carefully put the electromagnetic beads that had been made, and then began to repeat the production, one palm needs fourteen electromagnetic beads, and one big white needs twenty-eight.

Ten big whites need 280 pieces, except for the first time it takes two hours to be unskilled, and the fastest one for the rest also takes more than an hour, so it will take at least more than 300 hours to calculate.

This is just the electromagnetic ball, not counting the aluminum alloy finger knuckles!

As soon as he thought of this, Cheng Yuan felt how heavy his task was. At the same time, I also feel that scientific research is really time-consuming.

This is still the case that Cheng Yuan already has complete data, if those who have nothing to make it, it will take an unknown amount of time just to research!

Shaking his head, Cheng Yuan began to devote himself to his research work.

......

In the hotel of the high-tech park, Fabio got what he had always thought of from Cheng Yuan after the press conference.

The moment he got the thing, he immediately showed an extremely bright smile on his face, and his face turned red with excitement.

Back at the hotel, Fabio asked his assistant Corey to bring over the prepared computer as quickly as he could.

"Cory, I can't imagine that this operation will go so smoothly!" Fabio squinted his eyes, carefully looked at the USB flash drive that Cheng Yuan handed him, and said to Corey who was standing aside.

Standing behind Fabio, he glanced at Fabio coldly, and when he looked at the USB flash drive in his hand, a look of greed appeared in his eyes, and then he quickly reined in and said respectfully: "Mr. Fabio, let's finish our business as soon as possible, they may be in a hurry." ”

Cory reminded vaguely.

Fabio suddenly woke up and said, "You're right, they should be impatient, and I want to see what kind of technology is in here." Cheng Yuan, what an amazing genius!"

Muttering to himself, Fabio carefully inserted the USB flash drive into the computer, connected to the network at the same time, and opened a video communication software.

"Mr. Fabio, have you got it?"

As soon as I opened the software, an old face appeared on the opposite side, and the dark green eyes were full of light, revealing a trace of undetectable anxiety.

"Yes, Mr. James, the thing has been obtained. It's just a ...... between us" Fabio smiled and looked at the old man on the other side of the video, the smile on his face was even worse, he knew the identity of this old man very well, but it was precisely because of it that he knew how rich the other party was.

DuPont, the surname is not just an old name, it is also a synonym for wealth, although they are always quiet.

Of course, he also considered that he might have money to take and not be able to spend it. But driven by interests, he still released the greed in his heart.

"Hmph, don't worry. With a cold snort, James Dupont hissed: "Five million dollars have been remitted to your account, and I will send the remaining five million dollars to you after verification!"

Hearing that five million dollars had arrived, Fabio took a breath and quickly began to check his other private account, and when he saw the long list of numbers in the account, his face showed ecstasy.

"Thank you, Mr. James, you are so generous, I will pass the information over!" Fabio hurriedly copied the information from the USB flash drive, and then packaged it and sent it by email.

"Very good, I hope you don't do some smart little actions!" More than ten seconds after Fabio's email was sent, James on the other end of the video snorted coldly, and then cut off the communication.

When the screen went black, Fabio jumped up, looked at Corey with excitement on his face, and shouted, "Cory, do you see it? Five million! This is a number that I can't turn around in 50 years of work! And there will be five million in the future!"

"Oh my God! I'm going to think about how I'm going to spend this money, a cottage in the mountains, or a villa with a view of the sea?" Fabio lost all his graceful temperament, and he tore at his own light with a manoeuvre, threw the eyes on the bridge of his nose onto the bed, and walked frantically around the room, muttering incessantly.

On the side, Fabio's assistant watched Fabio's crazy movements and expressions coldly, he waited quietly for a moment, and when Fabio gradually recovered from the huge amount of money, he said in a low voice: "Sir, we are going to send this information back to the headquarters now, and they are also waiting for you." ”

"Yes, you're right, now is not the time to be happy, we need to send this information back to headquarters. Reminded by Corey, Fabio quickly came back to his senses, calmed his emotions, and after he sent the email to the internal mailbox of the World Health Organization, he was connected to the headquarters of the World Health Organization.

Soon, the video was connected.

"Good job, Fabio, we have received the information you sent, the technician has successfully opened the internal information of the medical chip, you have done a good job!" As soon as the video was connected, Fabio heard the continuous admiration from the other end, and his face suddenly showed an elegant smile.

"This is not my credit alone, although you did not come to Huaxia, your influence is still there. Fabio stopped his previous madness and looked at his colleagues very humbly.

After some exchange with the snake, Fabio cut off the communication with a smile on his face, and then handed the USB flash drive containing the information in his hand to his assistant, "Cory, destroy it." Until then, you have the right to use it. Fabio looked at his assistant meaningfully.

"Yes, sir!" Corey's eyes flickered.
