The technological empire begins with polymer materials

Gao Yuan was calm and immediately revealed the core parameters of Kunlun Aurora.

Then, he glanced at the screen of his mobile phone and found that the barrage was not as enthusiastic as he had imagined. It seemed that people were still thinking about the concept of thirty kilowatts per kilogram.

The next second, a raging barrage spewed out like a flood, and the speeches that blocked the sky plunged the entire screen into chaos.

"I'll go! Thirty kilowatts per kilogram!?"

"Equivalent to 40.8 horsepower!?"

"A motor weighing only ten kilograms can provide three hundred kilowatts of power!?"

“Oh my God, that’s crazy, isn’t it!?”

This is called not knowing, but it is shocking. According to the parameters of Kunlun Aurora, basically a fist-sized motor can easily drive the car and speed on the highway.

Gao Yuan smiled and continued: "In 2014, the German BMW company launched the world's most advanced LifeDrive motor structure, which can provide an average of three kilowatts of power per kilogram. In the following years, three kilowatts per kilogram has been It is a benchmark parameter in the motor field.”

Having said that, Gao Yuan stretched out ten fingers and said, "Now, through Kunlun Aurora technology, we have increased the energy density of the motor ten times! It reaches thirty kilowatts per kilogram!"

"As for why we can achieve such an energy density, it actually stems from the advanced material technology we have mastered. Please take a look."

Gao Yuan took out the ink pen from his jacket pocket, and the staff who had been waiting aside brought over the internal schematic diagram of the overclocked permanent magnet motor.

Gao Yuan held a pen and quickly wrote and drew on the drawing. At the same time, he said: "Everyone should have seen the Ferris wheel. The most fearful thing after sitting on it is the centrifugal force. If the speed is too fast, people will be thrown away. "Similarly, when the motor rotates at high speed, the conventional laminated rotor cannot withstand the huge centrifugal force, so special high-strength laminated or solid rotor structures need to be used."

"For permanent magnet motors, the problem of rotor strength is more prominent, because the sintered permanent magnet material cannot withstand the tensile stress generated by the high-speed rotation of the rotor, and protective measures must be taken for the permanent magnets; at the same time, because the motor rotor is in contact with the air High-speed friction in the gap will cause friction loss on the rotor surface, which will be much greater than that of a normal-speed motor..."

Gao Yuan wrote quickly. He used complicated mathematical formulas to calculate the stress, tension, heat, and resonance frequency that the overclocked permanent magnet motor needs to withstand when it is running.

"You see, ordinary materials cannot support such a high energy density. Although in 2002, the Swedish ABB Group launched an induction motor with more than 200,000 revolutions per minute, and the Japanese Mitsubishi Group also introduced high-speed switching reluctance. The motor can reach over 300,000 revolutions per minute.”

"However, due to material science limitations, such high-speed motors generally have low power and have little practical value."

"And our Kunlun Aurora technology uses a rotor made of super carbon materials that is not afraid of pulling force and high temperature at all! It is not a high-frequency motor, but a real over-frequency motor! It has a crazy speed that surpasses everything! If the torque is not considered Next, we can even make the Kunlun Aurora run at more than one million revolutions per minute!"

"The reason for all this is not only the mastery of materials science, but also because we use the world's unique multi-surface permanent magnet inner rotor technology!"

Boss Gao's small class has started again. He hardly gives people any time to think, and goes directly to the core part of Kunlun Aurora, quickly showing everyone the content that is not confidential and can be discussed.

"I was so confused that I only remembered one million revolutions per minute."

"I can't understand the concept of turning a million times a minute?"

"It's just a motor, does it need such a high speed?"

"Please listen carefully, okay? Boss Gao made it very clear that he will only do this if necessary. Normally, it is not necessary, so naturally the speed will not be so high."

"It's like Bolt can run 100 meters within ten seconds, but he will only go all out in the game. If he even buys fried chicken and runs like this, wouldn't he be crazy?"

Every time Gao Yuan starts a class, it always causes some students to think, which is a good thing.

"We are now calculating the torque of Kunlun Aurora." During the live broadcast, Gao Yuan continued to write furiously, "The friction coefficient of the permanent magnet rotor F=μm·g=0.3×10×9.807=29.4[N], and the load torque TL=F ·D/2·η=(29.4×10-3)/(2×20×0.9)=0.326[N·m]…”

"Blessed! It feels like I have entered the stage of listening to heavenly scriptures..."

"I could understand a little bit just now, but now I'm just confused..."

"Can anyone explain to me? What is torque?"

"How can a real boss have time to post barrages now? He is busy writing."

Phew~

Gao Yuan casually threw the ink pen in his hand and let out a sigh of relief.

"The above is about the principles of Kunlun Aurora. I have basically mentioned everything that can be said. If you can't talk about it, you can go back and think about it slowly. If you can figure it out, I will lose."

"In addition, relevant papers will be published on the Kunlun Wendao website and the March issue published next month. Everyone is welcome to check and order."

"As an important technology demonstration program of Kunlun Company, we not only target professional audiences, but also ordinary technology enthusiasts."

"After all, the reason why technology exists is to make everyone's life better, so next, we will play a short video to explain to everyone the changes that Kunlun Aurora technology will bring to everyone's lives."

Huh~

As Gao Yuan finished speaking, a promotional video began playing in the front.

In general, the Kunlun Aurora meets all the requirements for future power systems. The energy density is abnormal, the shape is changeable, the weight is light, the speed is high, the torque is high, the wear resistance is high, and the temperature resistance is high. Due to the extensive use of carbon materials, the Kunlun Aurora even It is also waterproof, even if it is thrown into the Mariana Trench, it will work continuously for decades without any problem.

As the short video played, everyone felt an unparalleled and huge shock.

The Aurora motor, which is made of carbon material as the main body, can even penetrate deep into volcanic lava and continue to work, as if there is no difficulty in this world that can stop it.

"I understand! The greatest ability of the Aurora Motor is not how fast it is or how powerful its torque is, but its indestructibility!"

"Heaven and earth! Omnipotent!"

"This is the exploration motor of the new era! It is specially designed for the harshest environments!"

"It's like an interstellar motor! Even if it's thrown to Jupiter, which has a harsh climate, it can continue to run for many years, right?"

"Not bad, if I have a spaceship, I will definitely use this kind of motor!"

The audience was excited. In terms of motor design and structure, Kunlun Aurora is certainly unparalleled in the world, but what really gives the motor its powerful superpowers is essentially the foundation of materials science.

Listening to the cheers from Chinese netizens, many Western netizens made bitter complaints.

"In the final analysis, it's just a motor, not a real black technology."

"It's just smaller in size, more powerful, and the materials are more durable."

"It's not that it can't be used! Take our multi-axis milling machine made in Germany as an example. The existing motor technology is enough. It doesn't mean that we can't survive without Huaxia Motor."

"It makes sense. Even if China masters Aurora Motor, will it be able to break our monopoly on high-end machine tools? Of course it's impossible, because machine tools are a huge whole, and motors are only part of it."

At this time, the five-minute short film had just finished playing, and the plateau appeared in the screen again.

For some reason, he changed his place, not on the road outside the company, but to the indoor sports ground.

"Welcome everyone back to the live broadcast." Gao Yuan said with a smile: "I believe that through the short video just now, everyone has understood that Kunlun Aurora technology is a huge upgrade to the earth's existing power system, ranging from aircraft and tanks to as small as shaving. The performance of knife vibrators will be doubled due to the emergence of a new motor."

"Nani? Vibrator?"

"The rhythm of driving when you have a disagreement?"

"Hahahaha, it turns out that Boss Gao is also an experienced driver!"

"The performance of the vibrator is doubled!"

"I'm so looking forward to it, sister, I'm getting wet..."

By accident, the barrage suddenly became dirty, but Gao Yuan remained unmoved and continued to speak in a calm tone.

"Please believe that the birth of a new technology is not just about transforming previous scientific and technological achievements. Many things that we did not dare to think about and could not do in the past will also be made possible by the emergence of new technology. Dreams come true again.”

“For example, the device I’m going to show you next, before there was an overclocking permanent magnet motor, it only existed in science fiction movies and people’s imaginations.”

“And once the Kunlun Aurora technology with incredible energy density becomes available, it will truly come into our lives from science fiction movies!”

After saying that, Gao Yuan smiled and raised his right arm to point to the end of the gymnasium.

Bang~

Bang~

Bang~

Following the sound of heavy footsteps, an employee of Kunlun Company was seen, wearing a powered exoskeleton similar to Iron Man, approaching the camera step by step.

This feeling of weakness is really uncomfortable. Even if you give me a peerless beauty at this moment, I can only look at it.

As winter approaches, everyone must remember to keep warm.
