Seeing Yang Chenglin's happiness, Tang Fei was happy, and couldn't help but ask, "What's the matter, so happy!"

Yang Chenglin said: "Boss, a businessman from the south took the initiative to come to the door and asked to order 500,000 USB flash drives from us. ”

"Oh, and such good things. ”

Yang Chenglin nodded and said: "Yes, he is in my office, just now we were talking about the U disk order, I heard that you went back to the office, I came over to tell you about this great thing." ”

It seems that their own USB flash drive is becoming more and more popular, and more than one million were ordered at the three-day industrial exhibition in Shenhai City, not long after returning from Shenhai City, someone actually took the initiative to find the door, and as soon as I opened my mouth, it was 500,000 USB disks.

500,000 USB flash drives, which should be the largest single large order received so far. Tang Fei said happily: "It's okay, you negotiated with the other party and signed the contract." ”

There are some things that Tang Fei doesn't need to do personally. For the signing of a contract like this, the price basically does not need to be discussed, it has already been set, and all that needs to be negotiated is the delivery period, which Yang Chenglin can handle.

For the cadres of the summoning department, Tang Fei was very relieved, and this matter was handed over to Yang Chenglin to do.

Yang Chenglin happily returned to his office, and the big boss from the south drank tea and settled the business.

The boss is also very happy, because Jiuzhou Industrial Co., Ltd. clearly marked the price, Tong Su is not bullied, and anyone who comes to the door is this price.

As for taking the initiative to send a car to Jiuzhou Industrial Co., Ltd. to pull goods, he seems to have heard of this rule and has long been surprised.

The two negotiated everything and signed this order for 500,000 USB flash drives.

In this way, Jiuzhou Industrial Co., Ltd. holds more than 2 million U disk orders, and in the huge U disk manufacturing workshop, the production line is constantly producing and manufacturing U disks, so busy.

Workers pack the packaged USB flash drive and transport it to the large warehouse in the logistics and warehousing center one by one, and the customer will send a car or entrust a team to pull their goods from there.

Red Star Factory.

These days are particularly important to the Red Star Factory, and there is also a hint of festivity in this grandeur.

The first DJ4 electric locomotive has finally been successfully dismantled, and an expert team composed of a number of well-known domestic experts, plus several senior engineers from Siemens, is conducting a joint acceptance of this car.

Judging from the current acceptance situation, it is very gratifying, this car can fully meet the original expectations, and the indicators are basically qualified.

A second DJ4 locomotive was not far from the next station, where a series of assembly work was underway, and some specialists were also on board.

They saw that the traction motor system on this car seemed to be different, and hurriedly inquired, and learned that this was a joint development of Hongxing Factory and Jiuzhou Industrial Co., Ltd., and they were very interested.

As the chief engineer of the Red Star Factory, Xie Zhenhua introduced the main performance of this traction motor system to the experts, and after listening, many experts gave a thumbs up.

An expert with gray hair and reading glasses said that he did not expect that in his lifetime, he could see such an advanced and excellent traction motor system in our country.

Seeing the old expert like this, Xie Zhenhua felt sincerely proud. At the same time, I also know in my heart that the Red Star Factory is stained with light, and this traction motor system is actually developed by Jiuzhou Industrial Co., Ltd., but it is only a joint development.

Some experts suggest that since the performance of this traction motor is so good, the third DJ4 electric locomotive can be equipped with our domestic traction motor system, and there is no need to install Siemens.

As we all know, the sooner the DJ4 electric locomotive is made in China, the better, and experts wish that all the important parts on the electric locomotive are domestic.

At present, the degree of localization of the DJ4 electric locomotive is too low, and the slightly more important parts are provided by Siemens, and the Red Star Plant is only responsible for assembly.

After a few days of joint acceptance, the Red Star Plant successfully passed.

The first DJ4 electric locomotive was draped in red and was very festively pulled out of the assembly workshop and began to enter the delivery workshop.

Soon after, it will begin a series of performance verification tests, including form tests, and finally will also be run on the railway.

Looking at the electric locomotive that was slowly being pulled out amid everyone's cheers, Xie Zhenhua felt that the corners of his eyes were a little moist.

I think back to the scenes, from the beginning of contact with Siemens, to the beginning of substantive negotiations, to the conclusion of an agreement, to the start of manufacturing, and so on......

It's not easy!

Among the hardships, Xie Zhenhua has the most right to speak, but now it's okay, the first car finally got off the car and successfully passed the joint acceptance of the expert group.

Xie Zhenhua's eyes were retracted, looking at the second DJ4 electric locomotive in assembly, and said in his heart, with the experience and foundation of the first unit, the second and third units, the assembly progress will be smooth, and the process should be faster.

Thinking that from the second unit, the traction motor system will be completely localized, Xie Zhenhua has a little expectation, what will the DJ4 electric locomotive with our localized traction motor system look like?

These days, the Red Star Factory is very lively.

Tang Fei also took the time to go there to feel the lively atmosphere, and also saw the first DJ4 traction motor that had been dismounted.

However, Tang Fei spent most of his time in his own company, in addition to paying attention to the production and construction of his own company, he was also concerned about the development of his first servo motor.

For this motor, Tang Fei had already figured out the general design ideas and built a general design framework, which was developed by Luo Dong, a motor expert, and jointly developed by several motor experts, including Zhengcheng, Wang Weixin and Ma Kang.

Because of Tang Fei's design ideas, everyone started the design on this basis, and the progress has been good, and many things have been completed.

If you don't break the technical things, you may find it difficult, but once they are broken by others, you will suddenly realize.

Several experts such as Zhengcheng, Wang Weixin and Ma Kang felt this way, and after they digested and fully understood Tang Fei's design, they immediately understood it, and the design was also smooth.

This is a very good servo motor, although Ian Donnelly did not say exactly what it will be used for, but it is clear from the technical requirements he provided that this servo motor will definitely be used in CNC machines.

With the cooperation with Ian Donnelly for a long time, Tang Fei knew that the company to which Ian Donnelly belonged had a relatively miscellaneous business, providing accessories for many large companies in the world, and this motor should also be supplied to a famous machine tool manufacturing company.

When the first DJ4 motor of Hongxing Factory drove out of the delivery workshop in a cheer, the design and development of Tang Fei's servo motor was also nearing the end and was basically completed.

A large number of design drawings, technical data, placed on Tang Fei's desk, as the real chief designer of this motor, Tang Fei wants to personally take a look at everyone's design results.

The advanced thing about this motor lies in its control system, which is equipped with a microprocessor and a new digital signal processor, a digital control system in the true sense, and the control part can be carried out with software.

The chip adopts the current mainstream industrial control chip, which is a servo motor developed by Jiuzhou Industrial Co., Ltd.

Tang Fei has his own plan, planning to develop a total of eight series of servo motors, the power range of 0.05~10k, to form a relatively complete system, to meet the different needs of working machinery, handling mechanisms, welding robots, assembly robots, electronic components, processing machinery, printing machines, high-speed winding machines, winding machines, etc.

This is its first servo motor, temporarily classified as a member of the A series, in the future will develop B, C, D, E, F, G, H and other series, with different power, different speeds, for different fields.

Tang Fei's own technical skills are very profound, and he personally carefully reviewed everyone's designs, which took a few days, and after reading it, he was very satisfied on the whole, just combining the knowledge in his mind, and slightly improving a few small places.

After reading it, the design is basically settled like this.

Obviously, Ian Donnelly is very concerned about the design and development of servo motors, listening to Yang Chenglin, he has completed the design and development, and has begun to prepare for manufacturing, he immediately rushed to Qingjiang City, accompanied by a senior engineer in the field of motors in their company - Steve James.

Unexpectedly, as soon as he heard that the servo motor was designed, Ian Donnelly hurried over, and the efficiency was so high that it was a little beyond Tang Fei's expectations.

Sometimes, Tang Fei will think, what's wrong, Ian Donnelly is so concerned about this motor, is this motor important to them.

Well, very likely.

Ian Donnelly came, and also brought a senior engineer in the field of servo motors, as soon as they arrived at Jiuzhou Industrial Co., Ltd., they immediately entered the working state.

In the conference room, the materials are also prepared, including the basic introduction of this motor, as well as technical information, which are displayed in front of Ian Donnelly and Steve James through projection.

The first is a basic introduction to this motor.

Luo Dong also came over and personally introduced the motor he presided over the research and development.

Ian Donnelly isn't very good at technical things, he's mostly a businessman, and his expression is normal.

But Steve James is different, he is a senior engineer in the field of servo motors, and after listening to Luo Dong's introduction, his face gradually changed.

From calm at the beginning, to surprise, to disbelief, and now with a face full of shock, he looked at Luo Dong, and then at several motor experts sitting in Jiuzhou Industrial Co., Ltd.

Ian Donnelly finally noticed that Steve James's face was a little abnormal, and quickly turned his head sideways and asked in a low voice.

Gradually, Ian Donnelly's face also changed, and he asked in a low voice, "Steve, you are sure, there is no mistake." ”

Steve James affirmed: "There is no mistake. ”

Ian Donnelly nodded, he brought it up, he had something to discuss with Steve. Tang Fei nodded and motioned for the two of them to please.

The two of them walked out of the conference room together, and talked in a low voice in the corridor outside, and they didn't know what they were talking about, and it took ten minutes before the two entered the conference room and sat down again.
