Chapter 222 Surprise
Chapter 222 Surprise
460Ps maximum horsepower is more than enough for a family car, but it is obviously not enough for a heavy truck of dozens or even hundreds of tons.
Therefore, Kang Chi directly upgraded the motor and kept an eye on its parameters. After two upgrades, its parameters have become:
[Maximum speed 30000RPM, maximum horsepower 1500Ps]
Well, 1500Ps horsepower is enough even for a heavy truck.
So Kang Chi directly analyzed it.
Structural analysis, mastery points -5,
Material analysis, mastery points -10,
Process analysis, mastery points -10.
After investing 25 mastery points, a lot of information began to flow into Kang Chi’s mind, and because the technical level leap was not large, Kang Chi easily mastered the technical information in this motor.
The structure and process are not a big deal, but what surprised Kang Chi was the magnet material of this motor.
If we talk about limiting the development of human technology, it must be the material.
Humanity does not lack cutting-edge scientific and technological theories, but the biggest limitation to applying theories is actually the material.
Whether it is the permanent magnet synchronous motor or the synchronous reluctance motor mentioned above, they actually use the same material to achieve performance improvement through design optimization.
When the performance reaches a limit, it is difficult for people to break through this performance barrier through design.
The only thing that can be done at this time is to change the material and improve the performance of the material itself.
Not only motors, but also chips are the same. If semiconductor materials are not further improved, the chip manufacturing process will be limited by the size of silicon atoms and will always be locked at 1.5-2nm.
Similar examples are numerous in the development of science and technology. The performance of the motor in front of Kang Chi is almost 500Ps higher than that of Tesla’s IPM-SynRM. In addition to the more sophisticated design, the performance improvement of the magnet material is the most important factor.
There are many kinds of magnet materials known in the world. The most common ones are injection molded ferrite, bonded NdFeB, and sintered ferrite.
And the strongest magnetism must be sintered NdFeB magnets, also called neodymium magnets.
Neodymium magnets are made of alloys such as neodymium, iron and boron to form a tetragonal crystal structure of Nd2Fe14B. The maximum energy product MGOe (mega gauss oersted) can reach N55, which is the highest magnetic material that humans can currently create.
And from the neodymium in its name, it can be seen that it is a rare earth magnet.
Old M and other countries are very afraid that China will hold their rare earth resources neck, and strong magnetic materials account for a large part of the reason.
Without neodymium, they can’t even make a good motor!
The magnet in Kangchi’s motor is also a neodymium magnet.
It’s just that it adds two other rare earth materials: erbium and dysprosium on the basis of the original alloys of neodymium, iron and boron. This not only strengthens the magnetism, but also improves the coercive force.
In addition to the improvement of the material formula, in the manufacturing process, it also uses smelting equipment similar to the floating belt method single crystal furnace used to manufacture semiconductor-grade silicon rods. Through hundreds of repeated refining, it pursues the ultimate material purity of 16 nines.
This makes its maximum energy product MGOe (mega gauss oersted) directly as high as N90, which is 63% higher than the ordinary sintered iron boron neodymium magnet!
This made Kang Chi couldn’t help but secretly exclaim: “Awesome!”
You know, the difficulty and significance of improving the performance of magnetic materials to this extent is no less than the development of the next generation of semiconductor materials.
With this super-strong magnet, not only will the performance of the motor be stronger, but the motor with the same performance can also be made smaller and lighter.
However, the addition of two rare earth materials and the increased difficulty of the process make its manufacturing cost higher, and it is only suitable for more advanced civilian fields. And its role in the military field is needless to say.
The simplest thing is to replace the magnets on the electromagnetic catapult of the aircraft carrier with this super-strong magnet, which can greatly improve the efficiency and performance of the catapult.
Things that could not take off on the aircraft carrier before may be able to take off in the future, and now the carrier-based aircraft can also hang more ammunition when taking off.
In addition to the electromagnetic catapult device, including electric equipment such as drones and remote-controlled robots,They can also enjoy the performance improvement brought by this material.
The military bosses will definitely like this thing!
In order to thank the military for its protection and for helping him build the Pangu base, Kang Chi plans to convert the sodium battery production line of Datang Heavy Industry into a lithium battery production line, and use the sodium battery technology with an energy density of 500wh/kg to manufacture ultra-high-end solid-state lithium batteries for the military.
Now there is this super strong magnet, and the surprise is doubled!
In fact, in addition to the military field, this super strong magnet will also have a place in many cutting-edge fields. For example, if the device of controlled nuclear fusion is replaced with this magnetic material, the magnetic confinement performance can be further enhanced, and the duration of ignition is likely to be further improved.
Kang Chi wanted to continue upgrading, but when he saw the remaining 14 mastery points on the system panel, he silently gave up the idea…
Recently, in order to quickly promote the battery swap mode, he has been using too many plug-ins. Not to mention mastery points, even general experience is almost a bit overwhelmed.
In the next few days, except for taking the elevator back to the villa for dinner, Kang Chi stayed at the Pangu base all the time and used a plotter to draw the production equipment drawings for manufacturing this motor.
Of course, not every link of the equipment needs to be rebuilt. Most of the equipment is ready-made. Some special ones, such as the floating belt purification furnace, only need to be improved on the basis of the original single crystal furnace.
In order to accumulate more mastery points, after the drawings were drawn, Kang Chi only asked Yan Hui to make the parts according to the drawings, and then transported them all to the Pangu base, and he completed the assembly and manufacturing by himself.
In order to improve efficiency, Kang Chi also asked Bai Niu to manufacture three level 1 industrial robots, and then through upgrading, they obtained Bai Niu No. 2, No. 3, and No. 4.
With these four intelligent robots, the manufacturing speed of this motor production line immediately increased several times. Basically, a truckload of new parts was shipped in every day, and they were digested in less than half a day. Kang Chi even had plenty of time to use the learning machine to recharge and learn.
……
A new fighter aircraft research and development base in the northwest region.
After inspecting the improved test of the WS-20 engine, Cai Yaobin was about to attend the next technical analysis meeting. His deputy suddenly ran over and whispered in his ear: “Mr. Cai, Dr. Kang just called you.”
”Kang Shengyu? What did he want to talk to me about?”
”Not Dr. Kang Shengyu, but Dr. Kang Chi…”
”Kang Chi?!”
Cai Yaobin was immediately surprised and asked: “What did he say?”
”He said he had a surprise for you and asked if you had time to go to Dongyang to play.”
”Of course!”
Cai Yaobin quickly patted his deputy’s shoulder: “Hurry up and prepare the car… No, let’s go directly by plane!”
”Then the next technical analysis meeting…”
Speaking of this, Cai Yaobin’s mood suddenly became a little depressed, and he sighed: “The test results are not in line with expectations, let them analyze the reasons themselves, and we will go to Dongyang first!”
