Chapter 160:

Winding a coil sounds very simple, that is, winding a copper wire into a spiral to strengthen the magnetic field, using the smallest space to achieve the highest magnetic field strength. Please search for the most complete!
However, electromagnetic forming can effectively improve the forming properties of lightweight alloys, and the coil structure is one of the key factors affecting the forming quality.
So the coil is not what you want to make a few turns, but to determine the distribution of electromagnetic force according to the needs of the deformed part of the workpiece and design a suitable coil.
In other words, Cheng Yuan has to wind a coil of a certain length and number of turns inside the ball, which can conform to the standard.
Fortunately, Cheng Yuan, who owns artificial intelligence, does not have to be like those of ordinary scientific researchers, and has to do a little calculation by himself. Zero with a complete data source will soon be able to sort out all the data in combination with actual conditions.
Cheng Yuan glanced at the data displayed on the computer and started winding 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 strength, and magnetic pole area. Therefore, proper selection of electric or magnetic field parameters and geometric dimensions can obtain a certain bearing capacity and stiffness.
The electrostatic attraction or magnetic attraction is inversely proportional to the square of the distance between the objects. According to Anjou's theorem, this static system is static. In order to make the electromagnetic bearing work stably, it is necessary to use servo devices or adjust circuit parameters. control.
Electromagnetic bearings are generally composed of radial bearings, thrust bearings, servo control loops, dampers, speed sensors or position sensors.
However, these problems are very simple things for Cheng Yuan.
Although he can't do the ultra-large-scale magnetic bearing cluster control in the movie, but only five or six, for the intelligence in his hands, it can still be mastered.
Therefore, the technical difficulty is even higher than countless grades in movies.
Winding a coil is a technical task, especially the winding part is still inside a bead only about two centimeters.
After the length and number of turns given by zero, Cheng Yuan began to cut the copper wire. Then cut the cut copper wire into two and wind it around two screwdrivers. Winding requires dense and no voids, just this one step. It took Cheng Yuan more than 40 minutes to complete.
Carefully squeeze the coil slowly from the screwdriver into the inside of the ball, and then apply insulating paint. In the end, Cheng Yuan stuck a careful magnet on the poles of the two semicircles, and the first step was not completed.
The next step is to install the rotor and stator. This part is much simpler than the first part, but the workload is not much less, but it has increased a lot.
Inside a round bead. Four small stators need to be installed, and the role of the stator is to rotate the magnetic field. Ensure that the internal magnetic force is not leaked. The main role of the rotor is to be cut by the magnetic field lines in the rotating magnetic field to output current, which is the entire electromagnetic bearing work.
The small iron core is wound with a coil, and then welded with small electric welding, and is mounted on the external coil. After the four stators are installed in the four directions of southeast, northwest and northeast, the center rotor is inserted into it.
A simple radial electromagnetic bearing ball is thus made.
Carefully let go of the little thing that he spent almost two hours making, and Cheng Yuan started testing.
But before testing, he still needs to make an external controller, before he can install it on Dabai's palm. Cheng Yuan can only make a single controller to test. The manufacturing of the controller is simple. Two displacement annunciators and sensors are connected to a coil-wound magnet and then energized.
If it succeeds, the attraction force inside the electromagnetic ball will firmly hold the two magnets, and then the ball will start to move on its own at high speed.
Cheng Yuan only needs to control the size of the magnetic field through the controller to allow the ball to make different actions. Although they are all round, nothing can be seen, but as long as the ball can rotate. It can be proved that there are no flaws in his production.
"Zero, start the test and scan the operating status of the internal electromagnetic field."
Ready everything, Cheng Yuan press the power switch!
"No problem, sir."
Zero lightly answered.
quietly!
After Cheng Yuan turned on the switch, there was no current shuttle or special sound. Only the middle of the two magnets, the electromagnetic ball turned suddenly, but the ball did not pop out or stray away from the position. Under the equal magnetic attraction on both sides, the ball was firmly set to rotate between the two magnets.
Seeing this scene, Cheng Yuan immediately smiled.
"Successful, zero." Cheng Yuan sighed.
"Yes. Sir. The internal magnetic field is intact, the stator is stable, and there is no short circuit." Zero timely cooperation.
After hearing the zero report, Cheng Yuan was relieved, then turned the switch off, carefully placed the completed electromagnetic ball, and then began to repeat the production. Four palms were needed for one palm, and one large white You need twenty-eight.
Ten Dabai requires 280 tablets. In addition to the first unskilled hands, it takes two hours, and the fastest time is more than an hour. In this case, it will cost at least 300 yuan. Hours.
This is just an electromagnetic ball, not counting aluminum alloy finger knuckles!
Thinking of this, Cheng Yuan felt how heavy he was. At the same time, I felt that scientific research really took time.
This is still the case where Cheng Yuan already has complete data. If those people have nothing to produce, the research alone will take a lot of time!
Shaking his head, Cheng Yuan began to devote himself to his research work.
...
In the hotel in the Hi-Tech Park, Fabio got what he had always thought of from Cheng Yuan after the press conference.
The moment he got the things, his face suddenly showed an extremely brilliant smile, his face flushed with excitement.
After returning to the hotel, Fabio brought his assistant Cory to the prepared computer as fast as possible.
"Cori, I can't imagine this operation will be so smooth!" Fabio squinted his eyes, carefully hit the USB flash drive that he had given to him, and said to Curry standing aside.
Standing behind Fabio, he could glance at Fabio coldly, and when he looked at the USB flash drive in his hand, a greedy color appeared in his eyes, and he quickly converged. "Fabio Sir, let's finish our work as soon as possible, they may be anxious. "
Corey reminded vaguely.
Fabio suddenly woke up and said, "You're right, they should be impatient. I also want to see what kind of technology is inside. Cheng Yuan, really a great genius!"
Muttering to himself, Fabio carefully inserted the USB flash drive into the computer, connected to the network, and opened a video communication software.
"Mr. Fabio, is it already there?"
As soon as I opened the software, an old face that appeared more than a year old appeared on the opposite side. The dark green eyes were shining brightly, showing a trace of anxiety.
"Yes, Mr. James, things have already been obtained. It's just between us ..." Fabio smiled at the old man across the video with a smile on his face. The old man's identity was clear, but he It was because he was clear that he knew how rich the other party was.
DuPont, this surname is not only an ancient pronoun, but also a synonym for wealth, although they are always silent.
Of course, he also considered that he might have money to take, but didn't spend it. But driven by his interests, he still released his greed.
"Huh, rest assured." He snorted coldly, and James DuPont hissed, "Five million dollars has been remitted to your account. I will verify the remaining five million dollars and remit them to you!"
Hearing that five million US dollars had arrived, Fabio took a breath and quickly began to check his own private account. When he saw the length of the number in the account, his face exulted.
"Thank you, Mr. James, you are so generous, I will pass the information over here!" Fabio quickly copied the information in the USB flash drive, and then packed it and sent it by mail.
"Very well, I hope you don't do some conscious and clever gestures!" Ten seconds or so after Fabio's email was sent out, James at the end of the video snorted and then cut off the communication.
The screen turned black, Fabio suddenly jumped up, looked at Corey with excitement, and shouted, "Corey! Did you see it? Five million! This is something I can't turn over for 50 years. Numbers! And five million more! "
"Oh! God! I have to think about how I should spend this money, buy a villa or a sea view villa?" Fabio completely lost his original temperament, and he ripped apart his bright light. , Throwing the eyes on the bridge of the nose to the bed, walking frantically in the room, muttering in his mouth.
Aside, Fabio's assistant looked coldly at Fabio's crazy movements and expressions. He waited quietly for a while, when Fabio gradually recovered from the huge number of money, he said in a low voice: " We're going to send this information back to headquarters now, sir, and they're waiting for you. "
"Yes, you are right. We are not happy now, we will send this information back to the headquarters." Reminded by Corey, Fabio quickly returned to God, calmed his emotions, and he sent the email to This was connected to the WHO headquarters after the internal mailbox of the World Health Organization.
Soon, the video switched on.
"Good job ~ EbookFREE.me ~ Fabio, we have received the information you sent, the technician has successfully opened the internal data of the medical chip, you are doing a good job!" Once you connect the video, Fabio O heard the continuous admiration from that end, and his face suddenly showed an elegant smile.
"This is not my credit. Although you haven't been to Huaxia, your influence is still there." Fabio went crazy and looked at the colleagues very modestly.
After some imaginary communication with the snake, Fabio cut off the communication with a smile, and then handed the USB disk with the information in his hand to his assistant, "Corrie, destroy it. Until then, you have the right to use it. Fabio looked at his assistant with deep thought.
"Yes, sir!" Corey finally flashed his USB flash drive.
