Gate of Technology

Winding a coil, it sounds very simple, 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 forming properties of light alloys, and the coil structure is one of the key factors affecting the forming quality.

Therefore, the coil is not to be wound as many times as you want, but to determine the distribution of the electromagnetic force according to the needs of the deformed part of the workpiece and to design a coil that is suitable for it.

That is to say, Cheng Yuan needs to wind a coil of a specific length and number of turns inside the ball, so as to be able to comply with the standard.

Fortunately, Cheng Yuan, who has artificial intelligence, does not have to be willing to do a little calculation by himself like ordinary scientific researchers. Zero, who has a complete source of data, will soon be able to put all the data together 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, the electric displacement and the electrode area, and the magnetic field force is proportional to the magnetic field strength, the magnetic induction intensity and the magnetic pole area. Therefore, appropriate selection of electric field 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 Aner Hugh's theorem, this static system is statically indeterminate. 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.

But these problems are very simple things for Cheng Yuan.

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

Therefore, the technical difficulty is many levels lower than in the movie.

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

After the length and number of turns given by zero, Cheng Yuan starts to cut the copper wire. Then split the cut copper wire in half and wrap it around the two screwdrivers respectively. Winding requires dense and no voids, just this one step. It took Cheng Yuan more than 40 minutes to complete.

Carefully squeeze the coil from the screwdriver to the inside of the ball, then apply insulating paint. Finally, Cheng Yuan glued a careful magnet to each of the poles of the two semicircles, and the first step was 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 has increased a lot.

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

The small iron core is wound with coils, then welded with small electric welding, and installed on the outer coils. After the four stators are installed in four directions, the center rotor is inserted into it.

A simple radial electromagnetic bearing ball is thus made.

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

Before testing, though, he also needed to make an external controller, before installing it on Dabai's palm. Cheng Yuan can only make a single controller to test. The making of the controller is simple, attach two displacement annunciators and sensors to a magnet wrapped around a coil, and then energize.

If successful, the suction force inside the electromagnetic ball will firmly attract the two magnets, and 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 make the ball 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 mistakes in his production.

Zero, start the test, scan the operating state of the internal electromagnetic field.

Get everything ready, Cheng Yuan presses the power switch!

No problem, sir.

Zero responded lightly.

quietly!

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

Seeing this scene, Cheng Yuan immediately smiled.

Success, Zero. Cheng Yuan let out a sigh.

Yes. Sir. The internal magnetic field is in good condition, the stator is stable, and there is no short circuit. Zero cooperated in time.

Hearing Zero's report, Cheng Yuan breathed a sigh of relief, then turned off the switch, carefully placed the finished electromagnetic bead, and started repeating the production. One palm requires fourteen electromagnetic beads, and one large white Twenty-eight are needed.

Ten Taibais will cost 280 pieces. Except for the first time, it takes two hours to be unskilled, and the rest will take more than an hour at the fastest time. If you calculate this, you will have to pay at least more than 300. Hours.

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

Thinking of this, Cheng Yuan felt how heavy the task was. At the same time, I also feel that scientific research is really time-consuming.

This is still under the circumstance that Cheng Yuan already has complete data. If it is made by those who have nothing, it will take an inexplicable amount of time to research!

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

...

In the hotel in 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, a bright smile appeared on his face, and his face flushed with excitement.

After returning to the hotel, Fabio asked his assistant Corey to bring the prepared computer as quickly as possible.

Corey, I can't imagine that this operation will be so smooth! Fabio squinted his eyes, carefully scanned the USB flash drive that Range Yuan gave him, and said to Corey who was standing beside him.

Standing behind Fabio, you glanced at Fabio coldly, and when he looked at the USB flash drive in his hand, there was a look of greed in his eyes, and then quickly restrained, respectfully said: Fabio Sir, let's finish our business as soon as possible, they may be impatient.

Corey gave a vague reminder.

Fabio suddenly woke up and said, You're right, they should be impatient, and I really 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 the things arrived?

As soon as the software was opened, there was an old face that was more than a decade old, and the dark green eyes were full of light, revealing a trace of untraceable anxiety.

Yes, Mr. James, the things have been taken. It's just between us... Fabio looked at the old man opposite the video with a smile, and the smile on his face was even greater. He knew the identity of the old man, but he was It was because he was clear that he knew how rich the other party was.

DuPont, the surname is not only synonymous with old, but also synonymous with wealth, even if they are always silent.

Of course, he also considered that he might have the money to take it and spend it without life. However, driven by interests, he still released the greed in his heart.

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

Hearing that five million US dollars had arrived in the account, Fabio took a breath and hurriedly started to check the private account he had opened. When he saw the length of the long list of numbers in the account, his face showed ecstasy.

Thank you! Mr. James, you are so generous, and I'll pass the information on! Fabio hurriedly copied the information in the USB flash drive, packaged it, and sent it by email.

Very good, I hope you don't do some consciously clever 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 immediately, looked at Corey with excitement, and shouted: Corey! Do you see it? Five million! This is something I can't turn around in my fifty years of work. Numbers! And there are five million more to follow!

Oh! God! I have to think about how I should spend this money, buy a villa in a villa, or a villa with a sea view? Fabio completely lost his original elegant temperament, and he flexibly tore his own light. , threw the eyes on the bridge of his nose onto the bed, and frantically walked around the room, murmuring in his mouth.

On the side, Fabio's assistant looked at Fabio's crazy movements and expressions with cold eyes. He waited quietly for a while, and when Fabio gradually recovered from the huge amount of money, he said in a low voice: Sir, we are now sending this information back to headquarters, and they are waiting for you.

Yes, you are right, now is not the time to be happy, we are going to send this information back to headquarters. Remind by Corey, Fabio quickly recovered and calmed down his emotions. He sent the email to Only after the internal mailbox of the World Health Organization was connected to the World Health Organization headquarters.

Soon, the video is connected.

Good job, Fabio, we have received the information you sent, and the technicians have 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 other end. The continuous admiration brought an elegant smile on his face.

This is not due to me alone. Although you haven't been to China, your influence is still there. Fabio lost his previous madness and looked at his colleagues very modestly.

After a virtual exchange with Wei She, Fabio cut off the communication with a smile, and then gave the USB flash drive with the data in his hand to his assistant, Corey, destroy it. Until then, you have the right to use it. Fabio looked meaningfully at his assistant.

Yes, sir! Corey's eyes flashed when he found the USB drive.
