The first thing he wanted to make was to make a radial electric bearing device inside the ball, and the first step was cumbersome - the coil!

Wrap the copper wire around the coil along the inner wall of the ball

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. Please search () to see the most complete!

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, Ning Feng should wrap a coil of a specific length and number of turns inside the bead, and it can be attached to the standard.

Fortunately, Ning Feng, who has artificial intelligence, doesn't have to do a little bit of calculations by himself like those ordinary scientific researchers. Xiao Qi, who has a complete data source, will soon be able to sort out all the data in combination with the actual conditions.

Ning Feng 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 Ning Feng.

Winding the coil is a technical task, especially since the winding part is still inside a ball that is only about two centimeters.

After the length and number of turns given by Xiao Qi, Ning Feng began to cut the copper wire. The cut copper wire is then split in two and wound around two screwdrivers. Winding requires a dense and void-free process, just one step. It took Ning Feng more than forty minutes to complete.

Carefully squeeze the coil from the screwdriver to the inside of the ball, then apply the insulating varnish. In the end, Ning Feng 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.

Inside a bead. Four small stators are installed, and the role of the stator is to rotate the magnetic field. 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.

A small core, wound coil, and then welded with small electric welding, mounted on the outer coil, four stators are installed in four directions, southeast, northwest and northwest, and then the center rotor is embedded in it.

A simple radial electromagnetic bearing ball is thus made.

Carefully putting down the small thing he had spent nearly two hours making, Ning Feng began to test.

However, he also needed to make an external controller before testing it, before he could install it on the palm of Panda Mengmeng's hand. Ning Feng could only make one controller alone to test. The making of the controller is simple, two displacement annunciators and sensors are connected to a magnet wound around the coil, and then the power is applied.

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

Ning Feng only needs to control the size of the magnetic field through the controller to make the bead make different movements. Even though they are all round, you can't see anything, but as long as the beads can turn. It proves that there are no flaws in his production.

"Xiao Qi, start the test and scan the internal electromagnetic field operating state. ”

With everything ready, Ning Feng pressed the power-on switch!

"No problem, sir. ”

Xiao Qi replied softly.

Silently!

After Ning Feng turned on the switch, there was no current shuttle or special sound. Only in the middle of the two magnets, the electromagnetic bead rotated suddenly, but the bead did not pop out or deviate from the position, under the equal magnetic attraction on both sides, the bead was firmly set in the middle of the two magnets for rotation.

Seeing this scene, Ning Feng immediately smiled.

"It worked, Little Seven. Ning Feng let out a light sigh.

"Yes. Mr. The internal magnetic field behaves intact, the stator behaves steadily, and there is no short circuit. Xiao Qi cooperated in time.

Hearing Xiao Qi's report, Ning Feng 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 panda Meng Meng needs twenty-eight.

Ten pandas need 280 pieces, except for the first time it takes two hours to be unskilled, and the fastest one needs 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, Ning Feng 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 Ning Feng already has complete data, if he is asked to produce it by those who have nothing, it will take an unknown amount of time just to research!

Shaking his head, Ning Feng began to devote himself to his research work.

......

In the hotel in the capital, Lincoln got what he had always thought of from Ning Feng 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, Lincoln asked his assistant Corey to bring over the computer he had prepared as fast as he could.

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

Standing behind Lincoln, Ke glanced at Lincoln 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 retracted and said respectfully: "Mr. Lincoln, let's finish our business as soon as possible, they may be in a hurry." ”

Cory reminded vaguely.

Lincoln woke up and said, "You're right, they should be in a hurry, and I'd love to see what kind of technology is in here." Ning Feng, what an amazing genius!"

Muttering to himself, Lincoln carefully plugged the USB flash drive into the computer, connected to the Internet, and opened a video communication software.

"Mr. Lincoln, 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" Lincoln 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 he knew how rich the other party was.

Pooh, the surname is not just an old one, it's a name for wealth, even though 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 Winnie hissed: "The 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, Lincoln took a breath and quickly began to inquire about 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!" Lincoln hurriedly copied the information in the USB flash drive, and then packaged it and sent it by email.

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

When the screen went black, Lincoln jumped to his feet, looked at Corey with excitement, and shouted, "Corey! See? 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! Oh my God! I'm going to think about how I'm going to spend this money, a cottage on the mountain, or a cottage with a sea view?" Lincoln completely lost his original elegance, and he tore at his own light with a maneuver, threw the eyes on the bridge of his nose onto the bed, and walked frantically around the room, muttering incessantly.

On the side, Lincoln's assistant watched Lincoln's crazy movements and expressions coldly, and he waited quietly for a moment, waiting for Lincoln to gradually recover from the huge money figures, and then 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, Lincoln quickly came back to his senses, calmed his emotions, and sent the email to the internal mailbox of the World Health Organization, which connected to the World Health Organization headquarters.

Soon, the video was connected.

"Well done, Lincoln, we have received the information you sent, and 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, Lincoln heard the continuous admiration from the other end, and an elegant smile suddenly appeared on his face.

"This is not my credit alone, although you did not come to Hua*Xia, but your influence is still there. Lincoln was no longer as crazy as he had been, and looked at his colleagues very modestly.

After some false communication with the snake, Lincoln 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, "Corey, destroy it." Until then, you have the right to use it. Lincoln looked at his assistant meaningfully.

"Yes, sir!" said Corey, his eyes flickering.

Corey took a deep look at Lincoln, and then took the USB flash drive from the other party's hand, and when the USB flash drive was squeezed tightly in his hand, a flash of joy flashed in his eyes. ↑，

He had waited for this moment for too long!

Thinking of what he was about to get, Corey couldn't hold back his excitement and quickly left Lincoln's room, then hurried back to his room.

Lincoln looked at Corey, who was walking away, shook his head and didn't say anything, after all, everyone earns money together, and this is the best situation.

Dodging and hiding will only make something worse.

......

Japan, World Health Organization Headquarters.

A group of officers and organization experts gathered in front of the computer, staring in amazement at the tight cellular data structure on the screen.

"It's really ingenious design, that Hua * Xia's genius is really amazing, I have never seen such a tight cellular data structure, he is more than ten times tighter than any similar structure in the world!"

A computer scientist sat in front of the computer, looking at the pale blue hexagonal structure on the screen with his eyes mesmerized, and finally let out a sigh.
