The plateau was calm, and directly broke out the core parameters of Kunlun Aurora.

Then, he glanced at the screen of his mobile phone, but found that the barrage was not as enthusiastic as he imagined, and it seemed that people were still thinking about what kind of concept 30 kilowatts per kilogram was.

In the next second, the surging barrage tide gushed out like a flood, covering the sky and the sun, and plunging the entire screen into chaos.

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

"Forty .8 horsepower!?"

"A motor weighing only 10 kilograms can provide 300 kilowatts of power!?"

"Oh my God, that's crazy, isn't it!?"

According to the parameters of Kunlun Aurora, basically a fist-sized motor can easily drive a car and gallop on the highway.

Gao Yuan smiled and continued: "In 2014, BMW launched the world's most advanced LifeDrive motor structure at that time, with an average weight per kilogram, which can provide three kilowatts of power, and in the following years, three kilowatts per kilogram has been the benchmark parameter in the field of motors. ”

After that, Gao Yuan stretched out ten fingers, "Now, through Kunlun Aurora technology, we have increased the energy density of the motor by a full ten times!" Up to thirty kilowatts per kilogram! ”

"As for why we can achieve such energy density, it is actually due to our mastery of advanced material technology, please see."

I saw Gao Yuan take out an ink pen from his jacket pocket, and the staff who had been waiting early brought the internal schematic diagram of the overclocked permanent magnet motor.

Gao Yuan held a pen, wrote and painted quickly on the drawings, and said at the same time: "Everyone should have seen the Ferris wheel, the most afraid after sitting on it is centrifugal force, in case the speed is too fast, it will throw people away, in the same way, when the motor rotates at high speed, the conventional laminated rotor is difficult to withstand the huge centrifugal force, and special high-strength laminated pieces or solid rotor structure need to be used." ”

For permanent magnet motors, the rotor strength can be 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 magnet; At the same time, because of the high-speed friction between the rotor and the air gap of the motor, the friction loss caused on the surface of the rotor will be much greater than that of the normal speed motor..."

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

"You see, such a high energy density, ordinary materials must not be able to support, although in 2002, Sweden ABB Group launched an induction motor of more than 200,000 revolutions per minute, and Japan's Mitsubishi Group has also used high-speed switching reluctance motors, to achieve 300,000 revolutions per minute."

"However, due to material science limitations, such high-speed motors generally have little power and have no practical use value."

"And our Kunlun Aurora technology, which uses a rotor made of super carbon-based materials, is not afraid of tensile force and high temperatures! It's not a high-frequency motor, it's a true overclocking motor! Crazy revs that surpass it all! If we don't consider the torque, 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 material science, but also the use of the world's unique, multi-faceted permanent magnet internal rotor technology!"

Boss Gao's small class started again, he almost didn't give people time to think, went directly to the core part of Kunlun Aurora, and quickly showed everyone what could be said that was not confidential and could be talked about.

"I was confused, but I only remembered one million revolutions per minute."

"I can't understand what kind of concept it is to turn a million times a minute?"

"It's just a motor, do you need such a high speed?"

"Please, listen carefully, okay? Boss Gao said very clearly, if there is a need, he will do this, usually not need, naturally there is not such a high speed. ”

"It's like Usain Bolt can run 10 seconds in the 100 meters, but he will only give it his all in the race, and if he even buys a fried chicken and runs like crazy, isn't it a neurotic."

It is a good thing that Gao Yuan always arouses some students to think about every time a class starts.

"We now calculate the torque of the Kunlun Aurora." During the live broadcast, Gao Yuan continued to write hard, "The friction coefficient of the permanent magnet rotor is 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]…”

"It's a long life! It feels like I've entered the listening session..."

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

"Which big guy can explain? What is torque? ”

"How can the real bigwigs have the time to send barrages now, and they are all working hard to write."

Call~

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

"The above is the principle part about Kunlun Aurora, everything that can be said, I basically mentioned it, if you can't say it, go back and think about it slowly, if you can figure it out, I will lose."

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

"As an important technology display program of Kunlun Company, we are not only for professional audiences, but also for ordinary science and 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 you what changes will be brought to everyone's life after Kunlun Aurora technology."

Swish~

As Gao Yuan's voice fell, a promotional video began to play in front.

In general, Kunlun Aurora meets all the requirements of the future power system, the energy density can be called metamorphosis, the shape is changeable, the weight is light, the speed is high, the torque is large, the wear resistance, the high temperature resistance, due to the large use of carbon-based materials, the Kunlun Aurora is even waterproof, even if it is thrown into the Mariana Trench, there will be no problem in continuous work for decades.

As the short film played, everyone felt an incomparably huge shock.

The aurora motor, which is mainly composed of carbonaceous materials, can even go deep into the volcanic lava and work continuously, as if in this world, no difficulty can stop it.

"I see! The greatest ability of the Aurora motor is not how fast it is or how strong the torque is, but how indestructible it is! ”

"Heaven and earth! Omnipotent! ”

"This is the exploration motor of the new era! Built for the harshest environments! ”

"It's just an interstellar motor! Even if you throw it to Jupiter, which has a harsh climate, it can continue to operate for many years, right? ”

"Yes, yes, if I have a spaceship, I definitely need to use this kind of motor!"

The audience was excited, in terms of motor design and structure, Kunlun Aurora is of course unique in the world, but what really makes the motor gain powerful superpowers is essentially the foundation of materials science.

Listening to the cheers of Chinese netizens one after another, many Western netizens complained sourly.

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

"It's nothing more than a little smaller size, a little more horsepower, and a little more resistant to materials."

"It's not that it can't be used! Take our multi-axis linkage milling machine made in Germany as an example, the existing motor technology is sufficient, and it is not that it cannot survive without Huaxia Motor. ”

"It makes sense, even if Huaxia masters the Aurora motor, can it break our monopoly of high-end machine tools? Of course not, because the machine tool is a huge whole, and the motor is only one part of it. ”

At this time, the five-minute short film was just finished, and Gao Yuan appeared in the picture again.

For some reason, he changed places, not on the road outside the company, but to the indoor sports field.

"Welcome back to the live stream." Gao Yuan said with a smile: "I believe that through the short film just now, everyone has learned that Kunlun Aurora technology is a huge upgrade of the earth's existing power system, from aircraft tanks to razor shakers, and the performance will be doubled because of the emergence of a new motor." ”

"Nani? Vibrator? ”

"The rhythm of driving without saying a word?"

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

"The performance of the vibrator of the god meow has been doubled!"

"I'm looking forward to it, I'm wet with my sister..."

One was not careful, and the barrage suddenly became dirty, but Gao Yuan was unmoved and continued to speak in a calm tone.

"Please believe that the birth of a new technology is not only about the transformation of the previous scientific and technological achievements, but also many things that we did not dare to think of in the past, and we could not do things, but also because of the emergence of new technology, and the dream will be reflected into reality again."

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

"And once there is Kunlun Aurora technology with an energy density against the sky, it will really come into our lives from science fiction movies!"

With that, Takahara smiled and raised his right arm to point to the end of the gymnasium.

Bang~

Bang~

Bang~

With the sound of heavy footsteps, I saw an employee of Kunlun Company, wearing a powered exoskeleton similar to Iron Man, step by step, approaching the direction of the camera.
