The maximum horsepower of 460Ps is more than enough for a family car, but it is obviously not enough for a heavy truck of tens or even hundreds of tons.

Therefore, Kangchi directly upgraded this motor, and always paid attention to its parameters, until after two upgrades, its parameters have become:

[Maximum speed 30000RPM, maximum horsepower 1500Ps]

Well

1500Ps horsepower, even for heavy trucks, is completely sufficient.

So Kangchi directly analyzed it.

Structural Analysis, Mastery Point-5,

Material analysis, mastery point-10,

Process analysis, proficient point -10.

After 25 points of mastery, a large amount of information began to pour into Kangchi's mind, and because the technical level was not large, Kangchi had to master the technical information in this motor very easily.

The structure and process are nothing, what surprises Kangchi is the magnet material of this motor.

If you want to say that the development of human science and technology is limited, it must be the material.

In fact, there is no shortage of cutting-edge scientific and technological theories, but the biggest limitation in applying theories is actually materials.

Whether it is a permanent magnet synchronous motor or a synchronous reluctance motor mentioned above, they are actually made of the same material, and the performance is improved through design optimization.

And when performance reaches a limit, it's hard to design to break through this performance barrier.

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

Not only motors, but also chips, if the semiconductor material is not further improved, the chip manufacturing process will be limited by the size of silicon atoms, and forever locked at 1.5-2nm.

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

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

At present, there are many kinds of magnet materials known in the world, the most common ones are injection ferrite, bonded NdFeB, sintered ferrite,

And to say that the magnetism 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 a tetragonal crystal structure of Nd2Fe14B, and the maximum energy product MGOe (megagaussian auster) can reach N55, which is the highest magnetic material that human beings can make at present.

And from the neodymium in its name, it can be seen that it is a rare earth magnet.

Lao M and other countries are very afraid of Huaguoka's rare earth resource neck, and strong magnetic materials occupy a large part of the reason.

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

The magnet in Kangchi's motor also belongs to neodymium magnets.

It's just that on the basis of the original alloys such as neodymium, iron and boron, it has added two other rare earth materials: erbium and dysprosium.

This strengthens the magnetism and also improves the coercivity.

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, and pursues the ultimate material purity of 16 9s through hundreds of repeated refining.

This makes its maximum energy product MGOe (mega-Gaussian Oersted) directly up to N90, which is 63% higher than ordinary sintered FeB neodymium magnets!

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

You must know that the difficulty and significance of this degree of performance improvement of magnetic materials are no less than the development of next-generation semiconductor materials.

With this super strong magnet, not only the performance of the motor will be stronger, but the motor with the same performance in the past can also be made smaller and lighter.

However, there are two more rare earth materials, and the difficulty of the process has increased, making it more expensive to manufacture and only suitable for more sophisticated civilian fields.

And its role in the military sphere, needless to say.

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

What could not take off on an aircraft carrier in the past may be able to take off in the future, and now carrier-based aircraft can also hang more ammunition when they take off.

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

The military bigwigs of this thing must like it!

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

Now that there is this super strong magnet again, the surprise is directly doubled!

In fact, in addition to the military field, this super magnet will also have a place in many cutting-edge fields, such as the controllable nuclear fusion device If it is replaced with this magnetic material, the magnetic confinement performance can also be further enhanced, and the duration of ignition is likely to be further improved.

Kangchi originally wanted to continue to upgrade, but seeing the only 14 mastery points left on the system panel, he silently dismissed this idea......

Recently, in order to quickly promote the battery swap mode, it has been opened a little too much, not to mention proficient, and even the general experience is almost a little unbearable.

In the next few days, except for taking the elevator back to the villa during dinner, Kangchi spent the rest of the time at the Pangu base, using a drawing machine to draw the drawings of the production equipment for making this motor.

Of course, not every link of the equipment has to be rebuilt, most of the equipment is ready-made, some more special, 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 proficient points, after the drawings were drawn, Kangchi just asked Yan Hui to build the parts according to the drawings, and then transported them all to the Pangu base, where he completed the assembly and manufacturing.

In order to improve efficiency, Kangchi also asked Bainiu to manufacture three Level 1 industrial robots, and then through upgrades, Bainiu No. 2, No. 3, and No. 4 were obtained.

With these four intelligent robots, the manufacturing speed of this motor production line has immediately increased several times, basically a car of new parts are shipped in every day, and it is digested in less than half a day, and Kangchi even has a lot of time to use the learning machine to charge and learn.

……

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

After Cai Yaobin inspected the improvement test of the WS-20 engine, he was about to participate in the next technical analysis meeting, when his deputy suddenly ran over and whispered in his ear: "Mr. Cai, Dr. Kang just called you. ”

"Kang Shengyu? What is he looking for me? ”

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

"Kangchi?!"

Cai Yaobin's expression was immediately surprised: "What did he say?" ”

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

"Absolutely!"

Cai Yaobin hurriedly patted his deputy's shoulder: "Hurry up and prepare the car...... No, we'll fly straight to it! ”

"Then the next technical analysis meeting ......"

Speaking of this, Cai Yaobin's mood suddenly became a little lower, and he sighed: "The test results do not match expectations, just let them analyze the reasons themselves, let's go to Dongyang first!" ”
