Technological power starts with upgrading lenses.

Chapter 222 Surprise

The maximum horsepower of 460Ps is more than enough for a family car, but it is obviously not enough for heavy-duty trucks with dozens or even hundreds of tons.

Therefore, Kangchi directly upgraded the motor and always paid attention to its parameters. After two upgrades, its parameters have become:

[Maximum speed 30000RPM, maximum horsepower 1500Ps]

Ok,

1500Ps horsepower is completely enough even for heavy-duty trucks.

So Kangchi analyzed it directly.

Structural analysis, mastery points -5,

Material analysis, mastery points -10,

Process analysis, mastery points -10.

After investing 25 proficiency points, a large amount of information began to pour into Kangchi's mind, and because the technical level did not jump much, Kangchi was able to master the technical information of this motor very easily.

The structure and craftsmanship are nothing. What surprised Kangchi was the magnet material of this motor.

Countries such as Lao M are very afraid that China will choke their rare earth resources, and strong magnetic materials account for a large part of the reason.

In fact, mankind does not lack cutting-edge scientific and technological theories, but when it comes to applying the theories, the biggest limitation is actually materials.

This makes its maximum energy product MGOe (Megagauss Oersted) directly as high as N90, which is a full 63% higher than ordinary sintered iron boron neodymium magnets!

This made Kang Chi couldn't help but secretly exclaim: "Awesome!"

Not only motors, but also chips. 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.

As you can see from the neodymium in its name, it is a rare earth magnet.

It’s just that based on the original alloys of neodymium, iron and boron, two other rare earth materials are added: erbium and dysprosium.

This not only strengthens the magnetism, but also increases the coercive force.

Whether it is the permanent magnet synchronous motor or the synchronous reluctance motor mentioned before, they actually use the same materials and achieve performance improvement through design optimization.

There are many kinds of magnet materials known around the world. The most common ones are injection molded ferrite, bonded NdFeB, and sintered ferrite.

The only thing that can be done at this time is to change the material and improve the performance of the material itself.

The magnets in the Kangchi motor are also neodymium magnets.

After the performance reaches a limit, it will be difficult for people to break through this performance barrier through design.

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 refinements, it has pursued the ultimate material with 16 nines. purity.

To say that the magnet is the strongest, it must be a sintered iron boron neodymium magnet, also called a neodymium magnet.

Neodymium magnets are made of alloys such as neodymium, iron and boron, forming an Nd2Fe14B tetragonal crystal structure. The maximum energy product MGOe (Megagauss Oersted) can reach N55, making it the highest magnetic material currently created by humans.

Without neodymium, they can't even make a good motor!

There are countless similar examples in the development of science and technology.

The performance of the motor in front of Kangchi is almost 500Ps higher than Tesla's IPM-SynRM. In addition to the more exquisite design, the performance improvement of the magnet material is the most important factor.

To say that what limits the development of human science and technology must be materials.

You must know that improving the performance of magnetic materials to this degree is no less difficult and meaningful than developing 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 as before can also be made smaller and lighter.

However, the addition of two more rare earth materials and the increased difficulty of the process make its manufacturing cost higher, and it is only suitable for more sophisticated civilian fields. And its role in the military field goes without saying.

The simplest thing is to replace the magnets on the aircraft carrier's electromagnetic catapult with this super-strong magnet, which can greatly improve the efficiency and performance of the ejection.

What could not take off from an aircraft carrier before might be able to take off in the future, and now carrier-based aircraft can also carry more ammunition when taking off.

In addition to electromagnetic ejection devices, electric equipment such as drones and remote-controlled robots can also enjoy the performance improvements brought by this material.

The military bosses will definitely like this!

In order to thank the military for protecting him all the time and for helping him build this Pangu base, Kangchi plans to change the sodium battery production line of Datang Heavy Industry into a lithium battery production line, using sodium batteries with an energy density of 500wh/kg. technology to manufacture ultra-high-end solid-state lithium batteries for the military.

Now with this super strong magnet, 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 for 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 improvement.

Kang Chi originally wanted to continue upgrading, but when he saw that there were only 14 mastery points left on the system panel, he quietly gave up the idea...

Recently, in order to quickly promote the battery swapping mode, there have been a lot of hang-ups. Not to mention being proficient, even the general experience is almost too much.

In the next few days, except for taking the elevator back to the villa when eating, Kang Chi stayed at the Pangu base the rest of the time, using a drawing machine to draw the drawings of the production equipment for the motor.

Of course, not every piece of equipment needs to be rebuilt. Most of the equipment is already available. Some of the more 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 proficiency points, after the drawings were drawn, Kang Chi just asked Yan Hui to make the parts according to the drawings, and then transport them all to the Pangu base for him to complete the assembly and manufacturing himself.

In order to improve efficiency, Kangchi also asked Bainiu to manufacture three level 1 industrial robots, and then upgraded them to get Bainiu No. , No. , and No. .

With these four intelligent robots, the manufacturing speed of this motor production line was immediately increased several times. Basically, a car of new parts was shipped in every day and was digested in less than half a day. Kangchi even had a lot of time. Use a learning machine to recharge your batteries and learn.

……

In the northwest region, a new fighter aircraft research and development base.

After Cai Yaobin inspected the improvement test of the WS-20 engine, he was preparing 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 does he want from me?"

"It's not Dr. Kang Shengyu, it's Dr. Kang Chi..."

"Kang Chi?!"

Cai Yaobin immediately looked surprised and said, "What did he say?"

"He said he had a surprise for you and asked if you have time to go to Dongyang."

"Of course!"

Cai Yaobin quickly patted the deputy on the shoulder: "Hurry and prepare the car... No, we will go directly by plane!"

"Then the following technical analysis meeting..."

Speaking of this, Cai Yaobin's mood suddenly dropped a bit, and he sighed: "The test results are not in line with expectations. Just let them analyze the reasons themselves. Let's go to Dongyang first!"
