Yesterday, Chang Jinlin and others returned to the Red Star Factory with the joy of signing the contract, and it seems that the whole factory area is celebrating, even ordinary workers know that the contract is successful, and in the near future, their factory will be an AC electric locomotive.

In the office.

Chang Jinlin made two cups of hot tea, one for himself and the other for Tang Fei. Picking up one of the cups and drinking it, Chang Jinlin thought.

The scene in the capital still comes to mind, and until now there is an unreal feeling, I thought that it would be a long negotiation like a long run to finally reach an agreement, but I didn't expect it to be so fast and so smooth.

Xiao Tang's head is flexible, and he suggested a change of strategy, and he reached an agreement with Siemens in such a short time, and a formal agreement has been signed in Beijing.

"Knock, knock, knock!"

There was a knock on the door of the office, Tang Fei came as promised, pushed the door in, and said loudly in an extremely festive tone: "Mr. Chang, congratulations!"

Chang Jinlin was in a good mood and smiled, "Xiao Tang, there is also your share of credit for this, if it weren't for your suggestion, things would not have gone so smoothly." ”

Chang Jinlin talked about their affairs in the capital, including some of the contents of this negotiation.

The Red Star Plant cooperates with Siemens Corporation, and Siemens provides technical guidance, and the Red Star Plant absorbs and consumes the technology of an AC electric locomotive of Siemens, and manufactures the AC electric locomotive at the Red Star Plant.

The only regret is that Siemens is still conservative in technology, and some key technologies have not been provided to the Red Star Factory, but only to supply spare parts to the Red Star Factory.

However, there is finally a perfect start, the cooperation between the two parties can be carried out, and the Red Star Plant will also be able to manufacture AC electric locomotives in the near future, provided that the technical guidance of Siemens AG is provided.

It is estimated that it will take many years for the Red Star Plant to independently develop and manufacture AC electric locomotives. Chang Jinlin's plan is five years, and within five years, the Red Star Factory can manufacture its own AC electric locomotive.

"Xiao Tang, now that the cooperation agreement has been officially signed, from today onwards, we will work hard and strive to make our first AC electric locomotive as soon as possible. ”

Tang Fei said: "Mr. Chang, I believe that your technical strength will definitely be able to develop your own electric locomotive." ”

At the same time, Tang Fei suggested: "Hongxing Factory should use this AC electric locomotive as a technical platform to carry out in-depth research and research, and on this basis, develop its own electric locomotive." ”

Historically, with this AC electric locomotive as a technical platform, Hongxing Factory developed the Harmony Electric 1 electric locomotive, followed by the in-depth localization, and successively developed a number of models, and finally had a Harmony series locomotive composed of many models.

Listening to Tang Fei's suggestion, Chang Jinlin nodded, "Well, I also plan to do this, the technical difficulty we are facing at present is the traction system of the electric locomotive, the control system and other core systems, and Siemens must have reservations in this regard, and we must rely on us to explore and tackle key problems." ”

Tang Fei replied with confidence: "Mr. Chang, and us, don't forget, we are a motor company, we have mastered the frequency conversion speed regulation technology of speed regulating motors, and there are experts like Luo Dong as technical consultants, we want to try the traction motor system of electric locomotives." ”

"Oh. ”

Feeling the strong self-confidence that erupted from Tang Fei's body, Chang Jinlin was slightly stunned at first, and soon smiled happily, "Xiao Tang, we almost thought of going together." ”

"Do you remember the phone call I gave you yesterday, saying that I had something important to look for you, but in fact, this is the case? Since Siemens does not provide us with the key technology of the traction motor system, then we will study it ourselves, I want to discuss it with you, and we will study it together, how about it?"

Chang Jinlin put forward such a request, mainly because of Tang Fei's technical strength in the field of motors. The Red Star Plant has experience in making electric locomotive traction motor systems, at least the motor traction systems of the Shaoshan series of electric locomotives are all developed by the Red Star Plant itself.

Tang Fei was overjoyed.

At present, we are building two large factories, and we want to do a big job in the field of motors, of which the field of electric locomotives is indispensable, and I have also had the idea of trying to make a traction motor system for electric locomotives.

The traction system, which is one of the core systems of the electric locomotive, is as important as the control system of the electric locomotive.

For example, Shaoshan series electric locomotives, each car generally has 6 high-power motors, which can achieve stepless speed regulation. They are the power source of electric locomotives, and the traction power of each car depends on these six high-power motors.

Each of these motors is large, high-tech, and valuable, and each one is worth hundreds of thousands.

Making such a motor has a great future and a lot of money to make, Tang Fei has long wanted to give it a try, and now seeing Chang Jinlin take the initiative to mention it, there was a burst of ecstasy in his heart.

Tang Fei said in a big way: "Well, let's cooperate well, let's start with the traction motor system of the Shaoshan series of electric locomotives, let's do the Shaoshan series of motors first, and after accumulating certain experience, we will work together to make the traction motor system of AC electric locomotives." ”

"Okay, that's it!"

Chang Jinlin agreed. In his opinion, the traction motor system technology of Shaoshan series electric locomotives is relatively mature, designed and developed by Hongxing Factory, and manufactured by Jiuzhou Industrial Co., Ltd. according to the drawings by a complete set of technical specifications and design drawings, so there should be no big problem.

As for the traction motor system of AC electric locomotive, the technical content is much higher, and Jiuzhou Industrial Co., Ltd. has accumulated a certain amount of traction motor manufacturing experience, and then we will study and tackle key problems together, and finally make the traction motor of AC electric locomotive.

The two negotiated the partnership.

For the time being, the technical specifications and technical drawings are provided by the Red Star Factory, and the traction motors of the Shaoshan series of electric locomotives are manufactured by Jiuzhou Industrial Co., Ltd., and the first batch is made, and then the mass production and manufacturing are carried out after passing the review.

When he came out of the Red Star Factory, Tang Fei couldn't help but want to laugh, Lao Tzu is finally going to start making traction motors.

Back to his company, Tang Fei immediately convened a meeting and announced that he would start making traction motors for Shaoshan series electric locomotives.

Some technical preparations were handed over to Zhao Ke and them to be responsible. Such as the industrial layout of the plant, what production equipment is needed, what tooling is needed, what raw materials are purchased, and so on.

Jiuzhou Industrial Co., Ltd. has two new factories, one of which will be used for traction motors, and the other for electric bicycle motors.

Don't underestimate the motor of the electric bicycle, although its value does not seem to be high, each unit is less than a thousand yuan, but the future market demand is very large.

Layout in advance, master the key and core technology of this brushless high-efficiency motor, and apply for a patent technology, even if you don't make this kind of motor in the future, it is estimated that you will make a lot of money just by relying on patent authorization.

Therefore, this kind of motor must be made, and the best electric bicycle motor must be produced and patented, which should be regarded as Tang Fei's advance layout.

What the!

We are going to make traction motors for electric locomotives, and some workers are shocked when they hear the news.

This is no ordinary thing. It's not that the workers don't know anything, some of their friends, relatives who work at the Red Star Factory, know exactly what a traction motor is.

"I heard you right, we're going to make traction motors!"

"There will be no mistake, this morning the boss called a meeting and it was formalized. ”

"Yes, I also heard that one of our two new factories will be used to make traction motors. ”

Such good news is inspiring, many people's spirits are shocked, and their hearts are full of emotion, especially some old employees of Jiuzhou Industrial Company, remember that a year ago, their factories were only dozens of people, and it was only how long it took to make traction motors.

Tang Fei is really going to make a traction motor!

One of the new buildings is completely in accordance with the process layout of the production and manufacturing of traction motors, which fully meets the manufacturing requirements of traction motors.

In the office.

Tang Fei roughly looked at the design drawings of the traction motor he got back from the Red Star Factory, but he just looked at it superficially, because there were indeed too many drawings, and in addition, Tang Fei had one more important thing.

Taking out white paper, pencils, erasers and rulers, Tang Fei sat down at his large desk and began to draw sketches of the design in earnest.

With his own memory, combined with the technical knowledge in his mind, Tang Fei is personally drawing a sketch of the motor design of the electric bicycle.

As long as the sketch is sufficient, the design principle is drawn clearly, and the relevant technical requirements are proposed, and the specific things should not be done by Tang Fei himself, and the following technicians can be handed over.

In addition, the latest batch of college students, a total of six people have been recruited, all undergraduates, fresh graduates majoring in mechatronics.

Jiuzhou Industrial Co., Ltd. is developing and growing, the development speed is still so fast, the treatment is also good, there is no lack of vision among college students, they choose here, ready to do a good career here.

No one bothered, quietly, patiently drew a few design sketches. Looking at it with satisfaction, Tang Fei thought in his heart that this is definitely the world's first brushless high-efficiency motor dedicated to electric vehicles, and he must apply for a patent in the future.

After the drawings were completed, Tang Fei called Zhao Ke with a phone call and told him to explain, and Zhao Ke took the drawings and left.

With such a design sketch, it is not a big problem for them to further design detailed design drawings. Back to the engineering and technology department, Zhao Ke held a short meeting, carried out the division of labor, and everyone took action to start the design of the motor of this special electric bicycle.

Design work is in full swing.

"Huh!"

Liu Jian is a fresh graduate this year, originally assigned to work, but he still chose to choose his own career, because he took a fancy to the development prospects and treatment of Jiuzhou Industrial Co., Ltd., he came here and became a technician of Jiuzhou Industrial Co., Ltd.

At this moment, he looked stunned, looking at the design sketch of the electric bicycle in front of him, in his impression, the motor of the electric bicycle is not like this at all.
