There are many kinds of motors on electric locomotives, the most important and important is the traction motor, which is the core power source of the electric locomotive, and there are generally six traction motors in a car.

Such a large motor, with high technical content and high value, will definitely not be given to Tang Fei for the time being, but has a fixed traction motor supplier.

In addition to the traction motor, there are other motors, such as the main cooling motor, which can be heard from Chen Guihong's tone just now, it seems that in addition to the previous main cooling motor, there are other types of motors that will be made for Tang Fei.

"Brother Chen, don't hang my appetite, talk to me quickly. ”

Chen Guihong said: "The leader has approved, and then purchase 2,000 main cooling motors from you, in addition, there are two models of motors for you to try, temporarily do a few samples, after loading and verification, it is estimated that a large number of purchases will be made from you." ”

Two thousand!

There's also a new motor to try out for yourself!

Hearing this, Tang Fei was overjoyed in his heart, this trip was really worth it, and there was such a big order. The 2,000 main cooling motors exceeded Tang Fei's expectations, and he originally thought that the Red Star Factory would order another 1,000 to 1,500 units, but he didn't expect it to be 2,000 units.

In addition, I actually made two other types of motors for myself, although this can only be regarded as a small and medium-sized motor, but each one sells thousands of dollars for sure.

I have succeeded in making these two motors, and there will definitely be a large number of orders in the future, because these two motors must be used in several cars in each car.

"Brother Chen, thank you so much. ”

Chen Guihong said: "Don't thank me, the main thing is to thank the chief engineer for the public opinion, and he insists on handing over the two kinds of motors to you to try." ”

Xie Zhenhua!

In his heart, Tang Fei's good impression of Xie Zhenhua increased again, this is a leader worthy of his respect, and he has helped him a lot several times.

Tang Fei didn't know, Xie Zhenhua insisted on doing this, and gave the two types of motors to Tang Fei to try to do, as long as it was because of the last time I read the "Qingjiang Daily", even the Americans introduced Tang Fei's frequency conversion speed regulation technology, Xie Zhenhua knew that Tang Fei's comprehensive performance of their speed regulating motors was world-class.

Such a motor manufacturing enterprise that has mastered the key technology of speed regulating motors, if you don't do it for them, who will do it? Under Xie Zhenhua's strong advocacy, these two motors were given to Tang Fei and their approval to try to make.

The above leaders have approved, but it does not mean that the order can be signed immediately, and the contract needs to be drafted. Chen Guihong communicated with Tang Fei and came over tomorrow to sign a formal contract.

Tang Fei readily agreed, anyway, he was not in a hurry for this day, tomorrow would be tomorrow.

The next day, Tang Fei went to the procurement center as promised, and signed a procurement contract with Chen Guihong for 2,000 main cooling motors, and also signed a trial production contract for the other two types of motors.

For the trial production of the new motor, the Red Star Factory did not provide specific design drawings, but only put forward the relevant technical performance requirements, installation interface size, etc.

This is what Xie Zhenhua meant.

Xie Zhenhua did not want to make a motor that was exactly the same as the original supplier, but asked Tang Fei to develop and design a better motor.

Re-research and development of two motors, Tang Fei said that there is no slightest pressure on technology, he not only has an authoritative expert in the field of motors like Luo Dong, but also three specialized motor technical personnel, will definitely be able to develop a motor with very good performance.

After the order was signed, Tang Fei started production at full capacity. Not only continued to make the main cooling motor for the Red Star Factory, but also began to develop those two motors.

Of course, the construction has also been going on, the foundation of the two large factories has been completed, and the workers of the construction team have been installing the steel frame, according to this progress, it is estimated that the main body of the two factories will be completed in another one or two months.

As for the Red Star Factory, in addition to normal scientific research and production, the focus is on technology introduction, hoping to introduce an electric locomotive from Ximen Company.

This is a relatively mature AC electric locomotive in the European market, with a relatively high technical content, which is a generation ahead of the current Shaoshan electric locomotive.

This kind of negotiation involves a lot of technical problems, Xie Zhenhua has almost become the main representative of the Red Star Factory, there are some things, especially technical things, even Chang Jinlin has to consult Xie Zhenhua's opinion.

Since last year, the Red Star Factory began to contact Siemens, more than a year has passed, and now it has begun to enter the substantive stage, many problems have been exposed, and the differences are relatively large, Xie Zhenhua feels very irritable.

As a reborn, Tang Fei remembers the events of the year more clearly.

In the matter of technology introduction, the Red Star Factory suffered a dumb loss, and after paying a huge price, it finally failed to introduce the core technology of others.

Without core technology, the Red Star Plant could only build a car shell, and the core components of the electric locomotive needed to be provided by Siemens, which seemed to have lasted for many years.

After many years of hard work, the engineering and technical personnel of Hongxing Factory basically studied each other's technology, cooperated with another large electric locomotive factory in China, and finally succeeded in producing the later Harmony series electric locomotives.

Watching Hongxing Factory and Siemens in contact, conducting rounds of negotiations, Tang Fei often thinks, what should I do?

Is it to watch the Red Star Factory pay a huge price and suffer a dumb loss, or is it appropriate to "remind" it?

Tang Fei was worried that his people would speak lightly, and the senior management of the Red Star Factory would not necessarily listen to his words. This is the main reason why Tang Fei has always maintained a wait-and-see attitude and has not taken action for a long time.

It wasn't until there was such an incident that Tang Fei decided to give it a try.

On the weekend, Tang Fei and Li Xueyan had dinner together in a Western restaurant with a good environment in the city center, which should be the first Western restaurant opened in Qingjiang City.

The business of this restaurant is not bad, Tang Fei ordered steaks, salads, appetizers and desserts, etc., and chatted with Li Xueyan while eating.

"Brother Fei, you don't know, my dad has been busy lately, he goes to work early every morning and comes back very late, I feel distressed when I look at it. ”

Tang Fei said: "It's a matter of technology introduction." ”

"Hmm. Li Xueyan said: "A working group has been set up in the factory, and my father and Chief Engineer Xie are both deputy team leaders, and they are very busy. ”

Li Xueyan added: "Not only are they busy, but they also seem to be under a lot of pressure, because Siemens does not compromise on some key and core technologies, and only agrees that they will provide these key and important parts, and our Red Star factory will assemble them, without providing specific technical drawings." ”

It's definitely not going to work.

Without key and core technology, you can only build a car shell, and the key and important parts have to rely on others, which is equivalent to being controlled by others.

Tang Fei said: "Harmony is definitely not good, since we want to introduce technology, we must introduce it together with their key and core technologies." ”

Li Xueyan shook her head and said, "Listen to my dad, it's difficult, and there's not much hope." ”

It's not that it's incomprehensible that if Siemens gives the key technology to the Red Star Plant, then they will lose their technical advantage in electric locomotives.

Siemens is sure to pursue the maximization of profits, not only to collect the high technology transfer fee of the Red Star Plant, but also not to give the specific technical drawings of the key and core components, but to provide the parts, the Red Star Plant is only responsible for the assembly, and finally assemble the electric locomotive in the Red Star Plant.

Red Star Factory.

Even if today is the weekend, several leaders have not rested, and are holding a meeting in a small conference room to exchange some opinions and opinions on the introduction of this technology.

Xie Zhenhua said with emotion: "After a few rounds of contact with others, I found that we have a gap in technology, they are AC electric locomotives, ours is DC electric locomotives, and the gap during this period is very large." ”

Chang Jinlin is the number one, he is an expert in business management, but he is worse than Xie Zhenhua in technology.

Chang Jinlin said: "Lao Xie, let me tell you, where is the gap in our technology?"

Xie Zhenhua said: "We use a DC motor, and people use an AC motor, which is the biggest difference. The motor used is different, the control mode is different, the DC motor uses the voltage change of the armature end of the motor, so as to achieve speed regulation, and the AC motor is the use of VVVF (variable voltage and frequency conversion speed regulation) for speed regulation, through the VVVF speed regulation mode, the control range is wide, and the AC motor is larger than the DC motor of the same volume, so their technical advantages are obvious. ”

"In addition, the control system is different, we know that the control system of the electric locomotive is one of the cores of the electric locomotive, and the control system is the most important in addition to the traction AC motor. The control systems we use are electronic cabinets and microcomputer cabinets. The people use a distributed network control system, which is a generation ahead, and I won't talk about the advantages of the control system. ”

After everyone listened to Xie Zhenhua's speech, there was a brief silence in the conference room.

After a long time, Chang Jinlin said firmly: "In this way, we must introduce their full set of technology at all costs." ”

Xie Zhenhua smiled bitterly.

Li Weibin said: "Mr. Chang, now our differences are mainly on the core and key technologies. The traction motor system of the electric locomotive and the control system of the electric locomotive are all core technologies on the electric locomotive, and Siemens does not agree to transfer these technologies to us. ”

A leader said angrily: "What kind of reputation is this, if the key technology is not transferred to us, then we can only build a car shell, and the key things still depend on others." ”

That's true.

This meeting has been held for a long time, but in the end there is no result, so we can only work harder, pin our hopes on another negotiation of Siemens, hoping that the next negotiation can resolve differences and achieve our own goals.

The Red Star plant was in a meeting, and several people from Siemens were also in a meeting.

They stayed at the Qingjiang Hotel, and several people spent the weekend summarizing the results of the previous rounds of negotiations and discussing what to do in the next round.

If there are leaders of the Red Star Factory next to them, after listening to the content of their conversations, it is estimated that they are in the mood to hang themselves.
