The core of permanent magnet traction is a permanent magnet motor, and the core is a large permanent magnet.

It is easy to say, but it is indeed more difficult to build, not only to ensure that in the use environment, there will be no temperature changes, resulting in fluctuations in the magnetic field of permanent magnets, but also to solve a series of problems such as vibration, impact, strength, etc., only a handful of countries in the world can be built.

Huaxia has a great advantage in this regard, which is rich in rare earth resources.

The reason why an old pedant like Zhu Dada can be hungry is because the improvement it brings is comprehensive.

Not only high-speed rail, but all large electric power equipment will benefit, and the temptation to reduce volume and weight alone is irresistible.

"It's easy to say, isn't it permanent magnet traction, permanent magnet is a thing that kindergarten children often play. Zhou Xing said very unkindly, and his attitude of not caring made Zhu Changda angry for a while.

Tang Yu's lips twitched, kindergarten? This Mr. Zhou fell to the ground and figured it out, the good image just now suddenly collapsed, and this eighty percent is also a second generation.

"En......" Tang Yu pulled a nasal voice, pondering how to say it tactfully, Zhu Dada couldn't help but speak.

"Mr. Zhou, this permanent magnet is not an ordinary magnet, that... That...", Zhu Dada didn't figure out how to explain it, it's really hard to talk about it to the uninitiated.

Zhou Xing wanted to roll his eyes, he was originally pretending to be stupid with a gag, but he took this real man and treated him as a real fool!

Tang Yu almost pouted under the table, this Zhu Dada was too straight, didn't he see that Zhou Xing was sloppy.

He gestured to him with his eyes, but Zhu Dada didn't seem to see it, and was still explaining his technical standards.

Zhou Xing didn't listen, but picked up the information and read it carefully.

Not to mention, it's no wonder that these people are tempted, and there are really a lot of good things that my country has taken out this time.

Needless to say, permanent magnet traction has greatly improved the stability and energy consumption level of high-speed rail. Although the country has taken out small motors, and large ship equipment cannot be used, it is of great significance to learn from, and even Qiu Houze's side may not be able to resist such a temptation.

Duoling Electric's precision servo motor is even more difficult to refuse, this thing has a wider range of applications, and it is infinitely useful for precision manufacturing alone.

If it weren't for Zhou Xing holding the Tinder spaceship, I am afraid that he would also be excited.

"It's really a good thing, and it's not an exaggeration. Zhou Xing closed the material and said with a smile.

"Who said it wasn't that!" Zhu Dale almost slapped his thigh, but turned around, "This technology is too critical, we know that Mr. Zhou has no benefit in this project, so I studied it before I came, if we can really reach a deal, some products of the Iron Research Institute can be handed over to Huanyu for production in the future." ”

Tang Yu's eyes were straight, his face was red, he was not afraid of god-like opponents, he was afraid of pig-like teammates, and he would throw out his hole cards when he came up, how should he talk about it next?

Even Tian Yixiong was stunned, and rubbed his nose with the back of his hand in embarrassment, this Tang Yu, how could he bring him to negotiate that! Okay, anyway, your Iron Research Institute doesn't care, and he is happy to see it.

Tang Yu He once wanted to take Zhu Dada, but it was just a technical matter, others couldn't do it, and in the end, he had to rely on Lao Zhu to check it.

Zhou Xing thinks this person is cute, at first glance, he is a skilled person, and his mental skills are too poor, such a person speaks straight, but he has no bad intentions, which changes Zhou Xing's opinion of him.

"I understand Zhu Gong's eagerness to build high-speed rail, but these things are not the best today!"

Not the best?

Zhu Dada was stunned, indeed, when it comes to the level of motors, China is in the forefront of the world, but compared with Germany, it is really a line behind.

He nodded silently, "Could it be that Mr. Zhou has a way to get Momofuku's technology?"

Zhou Xing shook his head, leaned forward slightly, and said with a smile: "Zhu Gong didn't think about domestic motors?"

Domestic motors?

Everyone was stunned, they didn't know why Zhou Xing mentioned this, this wasn't a slap in the face.

Domestic motors, in addition to the advantages of cheap price, what else is there?

The reliability is not good, the failure rate is high, and the accuracy is ...... Not to mention, the controls are simple, but the software is really rough.

Zhu Dada wanted to speak and stopped, the little hope that had just risen was shattered again, Mr. Zhou is still young, this is not a patriotic thing, the project is good, if it doesn't work, it can't be affected, otherwise there will be a big problem!

As soon as he saw their expressions, Zhou Xing understood.

He smiled, the person who laughed was inexplicable, but Liao Fan, who was familiar with him, faded his worry in an instant, and his long-lost smile, this kid was holding back what bad it was!

"Motors, you should use domestic ones!"

"Everyone, look at this album, Huanyu Technology also wants to make a difference in the electronic control industry, this is the first batch of motor samples, including the high-speed rail motor and precision servo motor you need. ”

Zhou Xing picked up the bag on the ground, took out a dozen product samples, and handed them to everyone present.

Tian Yixiong looked confused, this meeting, wasn't it opened to persuade Huanyu to exchange, why did it become a Huanyu product promotion meeting.

Zhu Dada saw that everyone had taken the sample, and also stepped forward to take a copy, since it was from Huanyu, this bit of face still had to be given.

"Minister Tian, if it is appropriate, I hope you can also help us promote it to Huanyu, the products below the M grade number in this sample can be exported. ”

"Huh

Tian Yixiong is subconsciously looking at the patterns inside, technically involving details, he doesn't understand, but the things inside don't look simple.

"Then why can't you go above M?" asked Tian Yixiong casually.

"The above are all strategic products, and you need to be certified by Huanyu VIP to buy. ”

……

"President Inoue, I wonder if you have received an invitation letter from Huaxia?"

"About motor products? Yes, I received it as well. Inoue responded.

This morning, he actually received an invitation letter from the Ministry of Economic and Trade of China on the promotion of motor products.

This time, Duoling Electric was originally the most relaxed, and it was originally to invite them to complete the technical exchange, but now, he was the most embarrassed, and the other party actually fought back in his own way!

"Huaxia's motors, it's not that I look down on them, this infrastructure madman, there may be a means to engage in large items, but the precision equipment of the motor is not suitable for them. Yowato's tone was proud, and his words were full of disdain for this event.

It is no wonder that Duoling has been immersed in the field of motors for decades and has proud capital.

Unexpectedly, there was silence on the other end of the phone, and I didn't see Inoue Yuhiko reply for a long time.

"Inoue-kun, are you listening?"

"I'm sorry, I..."

"Forget it, anyway, this time we have a request, let's go, I'll send my assistant to go with the group. Heng Luo Yi said nonchalantly, and then hung up the phone.

Inoue Yuhiko looked at the invitation in a daze, inexplicably, he felt that this time things were worse, it was too coincidental!
