The car giant started by marrying the daughter of the king

Chapter 329 Strengthening the Motor Industry
"The motors used in the stamping machines purchased by the stamping workshop from the Ji'er Machine Tool Factory need to be developed by BMW Motor. The motors used in previous electric bicycles were also developed by BMW Motor."

"The development of various motors such as engine starter motors and air conditioning compressor motors for our BMW cars is also handled by BMW Motors."

"Now they have to work on the motors used in welding robots. I'm worried they won't be able to handle it."

Although Jiang Hui provided him with a solution idea, Wang Feng was not so confident about BMW motors.

Any one of the above projects would be enough for many scientific research institutes to work on seriously for several years.

It is no wonder that Wang Feng is worried about not being able to handle the BMW motor.

"Many motor technologies are common. Once you have mastered one type of product, you can adjust the size to meet the needs of many occasions."

"When the time comes, I will personally lead the motor's technical team to tackle the technical problems."

After Jiang Hui said this, Wang Feng naturally had no questions.

People outside don’t know how high Jiang Hui’s technical level is, but the people inside BMW are very clear about it.

No matter what type of technical problem it is, it can be easily solved in Jiang Hui's hands.

The most important thing is that Jiang Hui can always come in from some special aspects and provide everyone with a very effective solution that is in line with the current technological level.

To some extent, Jiang Hui deserves the greatest credit for the rapid development of BMW.

"Director, I will sort out the equipment needed to expand the production line and the bottleneck products, and then report to you in detail."

After saying this, Wang Feng left Jiang Hui's office.

In order to get the motor out as quickly as possible, Jiang Hui went directly to BMW Motor next door to confirm the situation with chief engineer Wu Wei.

"We can now produce engine starter motors at the same level as our domestic counterparts, but there is still some distance to go before the technical parameters you specified."

"Next, I plan to improve the overall performance of the motor by improving the copper wire winding method and the material properties of the silicon steel sheet."

"We have already contacted Shougang for the project to improve the performance of silicon steel sheets, and they are very interested in this project."

After Wu Wei was recruited by BMW Motor, he has now moved to Shenzhen with his family to work. All technical personnel with a certain level of skills in the affiliated factories of Huazhong University of Science and Technology have also moved to Shenzhen. The remaining production factories are still retained for the time being to produce motors for BMW and other customers.

After arriving in Shenzhen, Wu Wei felt like a fish in water. Without those constraints, he devoted almost all his energy to the research and development of motor technology.

Jiang Hui also provided great support to BMW Motors, purchasing several advanced testing equipment from Japan and Europe to support the development of motors.

It can be said that although BMW motors are not very famous in China, their technical strength is not low at all.

Especially in the automotive industry, it will definitely be a king in the future.

"Shougang has a relatively deep technical foundation in silicon steel sheets. When I cooperated with them to develop high-strength steel plates for automobiles, they were quite enthusiastic."

"But when they were developing bearing steel later, they were a bit complacent and lost an opportunity."

"I think they will take it seriously if I ask them for silicon steel sheets this time."

All domestic steel mills are now state-owned.

BMW Motor can only choose the most suitable partner from these state-owned enterprises, and there are not many other options in the short term.

Therefore, finding Shougang, with which we have cooperated before, is a relatively good option.

"It is indeed as you said, Director. Shougang is more proactive this time. Now their chief engineer Zuo Guangsheng is in charge of this project."

"The demand for motors in various industries in China is very large. As a high-end special steel, silicon steel sheets are naturally in great demand."

"The key is that some key hydropower projects under the ministry have relatively high requirements for the technical improvement of generator sets."

"Projects in this area also require manufacturers such as Shougang to improve the performance of silicon steel sheets."

"To some extent, if the project that Shougang is cooperating with us on is really successful, they can apply for other projects in the future and produce results very quickly."

As an electric motor expert, Wu Wei naturally has a deeper understanding of the performance of silicon steel sheets, the main raw materials in electric motors.

Electric motors have been around for a hundred years, but up to now it has been very difficult to make any breakthrough changes or developments in some fundamental aspects.

The advancement of various motor technologies often involves adjustments in some details, making improvements bit by bit.

Or the performance of a certain material has changed significantly, resulting in a significant change in the performance of the motor.

Of course, in the future, with the advancement of chip technology and electronic control technology, there will be relatively large technological breakthroughs in motor controllers, which can drive a new round of changes in motor technology.

But that was many years later.

At this stage, Wu Wei and Jiang Hui are focusing on traditional technology improvement solutions such as silicon steel sheets and copper wire winding.

"Silicon steel sheets have the characteristics of high resistivity, low hysteresis loss and low eddy current loss, which can effectively reduce energy loss during motor operation and improve the operating efficiency of the motor."

"Our fastest way is to make some improvements in reducing iron losses, specifically..."

Since he is personally involved in this project, Jiang Hui must come up with some specific improvement plans, or at least point out the specific direction for everyone to work towards.

Otherwise it will be difficult to achieve a significant effect of saving time.

"The heat treatment process of silicon steel sheets is a critical process. High-temperature annealing of silicon steel sheets can eliminate internal stress and improve mechanical strength."

"We can make some adjustments to the temperature range..."

Jiang Hui spent more than ten minutes explaining his ideas to Wu Wei.

……

While Jiang Hui and Wu Wei were improving the AC motor technology, Shougang was actually not idle either.

"Lao Zuo, we must attach great importance to this cooperation with BMW Motors."

"I heard a rumor that the relevant departments might restart the discussion on building the Three Gorges Dam."

"Although there is no immediate result from the discussion, it will take a long time to officially start construction."

"But for us, it is a good opportunity to use these few years to improve the technology of silicon steel sheets. If we can then provide silicon steel sheets for the hydropower generators of the dam, it will definitely be a great achievement."

For Zhou Gang, the director of Capital Steel Plant, being able to provide supporting services for some large projects is definitely something that will show up in various summaries.

So many times, economic benefits are secondary, and other fame and fortune are more important.

"Director, rest assured, we will go all out this time." "Jiang Hui worked with us to promote high-strength steel plates for automobiles many years ago, and the high-strength steel plates for the current BMW Light are also provided by us."

"It can be said that high-strength steel plate has become the steel type with the best yield in our factory."

"I feel that the future of silicon steel sheets will not be worse than that of high-strength steel sheets for automobiles, but will only be better."

"In addition, silicon steel sheets can be used in a wider range of scenarios and are used in many key projects."

"So no matter from which aspect, we will actively work with BMW Motor to develop a new generation of silicon steel sheets."

As the chief engineer of Capital Steel Plant, Zuo Guangsheng is considered a professional in China's steel industry with a relatively high technical level.

The more professional you are, the more you can realize the importance of special steel plates.

China's steel production is actually not very low.

In the past two years, due to overcapacity, some backward production capacity had to be eliminated.

However, compared with the overall output, China's output of advanced steel plates is relatively low.

With the rapid development of economy, some special steels need to be imported from abroad.

High-end silicon steel sheets are no exception.

If Shougang can develop a new generation of silicon steel sheets in the future, then it will have the technology of high-strength automotive steel plates in one hand and the technology of silicon steel sheets in the other, and its future days will definitely be much more comfortable.

Even if we only work in these two areas, we can still gain a firm foothold in the domestic steel industry.

"I heard that Baosteel will start production next year. They are also considering introducing automobile steel plate technology from Japan. At that time, it will definitely have a certain impact on the development of our high-strength automobile steel plates."

"At this time, we need to develop some advantageous steel grades."

"Silicon steel sheets are a very good direction. Even if the help that BMW Motor can provide us is limited, we must continue our research and development work ourselves."

"It would be best if both sides could communicate well and see if they can make some breakthroughs as soon as possible."

Zhou Gang has already made up his mind to make silicon steel sheets the key research and development direction of Shougang in the future, and naturally hopes that Zuo Guangsheng can pay full attention to it.

"I understand that the requirements for silicon steel sheets vary depending on the usage scenarios of the motor."

"Whether it's the formula of silicon steel sheets, the thickness of rolling, or even the heat treatment of the surface, there are different requirements."

"They should be able to provide some constructive suggestions on the silicon steel sheets that BMW Motor needs. I have already communicated with Wu Wei, the chief engineer of BMW Motor."

"He is a well-known electrical machinery expert in China, and some of the suggestions he gave were very constructive."

"Next, I will personally visit and communicate with them to see if I can better promote this project."

Zuo Guangsheng actively reported to Zhou Gang the current communication situation with BMW Motor.

It can be said that both Shougang and BMW Motor are very enthusiastic about the silicon steel sheet project.

This is naturally very beneficial to the development of the project.

……

"Director, I heard that the BMW R&D Center is conducting preliminary development of CAD design software. I saw in some papers that some foreign companies are also considering using computer technology and some software to assist in the testing and development of motors."

"It seems that no manufacturer or school in China has done specific work in this area yet."

"I think that Baodian Motor could consider setting up a team to develop motor design and testing software. Based on our past experience, could we turn these things into a set of analysis and simulation software?"

As an electric motor expert, Wu Wei is naturally aware of the huge impact that computer software may have on the electric motor industry.

Now that Jiang Hui fully supports the development of BMW Motors, he naturally wants to take this opportunity to launch various projects that may be used.

In particular, the development of industrial software is time-consuming and costly.

The price of a computer is not cheap, and there are various other expenses.

At this time, the motor factories in China dared not even think about developing professional industrial software for motor design and testing.

That is to say, BMW Motor has foreign capital background, and Jiang Hui, the person in charge, understands technology and attaches importance to technology, especially things related to computer-aided design.

Another thing is that BMW Motor has no shortage of foreign exchange and has the opportunity to buy computers and other related auxiliary equipment from abroad.

Otherwise, if any of the conditions are not met, such a project will not be possible.

"No problem. BMW Motor aspires to be the largest and most professional motor manufacturer in China and even the world, so it must have some core products of its own."

"Industrial software related to motor design, test and simulation can be developed into our core technology. As long as we do this well, the efficiency can be greatly improved when developing new products in the future."

Whether for personal use or for future sales, industrial software is valuable.

Especially at this time, the global industrial software market is actually just starting out.

Even though other manufacturers started research very early, the progress was actually limited. After all, computer technology was too backward before, and it was only in recent years that there have been rapid changes.

Therefore, it is not too late for BMW Motor to enter the field of industrial software now.

Especially in the field of motors, it is even earlier.

Wu Wei originally thought that he would have to spend a little time talking to convince Jiang Hui.

After all, according to his estimation, if BMW Motor really develops its own software for motor design and test simulation, the final investment will definitely be more than one million RMB.

In 1984, an investment of this magnitude was not considered small.

Besides, this was just start-up capital, and he didn't know how long it would take to actually develop software that could be effectively used.

Maybe we will need another million to get the results in the future.

"Okay, I'll submit a formal project proposal next week!"

Jiang Hui agreed so readily today, Wu Wei must speed up the implementation of the project.

To avoid long nights and many dreams.
