Chapter 329 Consolidating the Motor Industry
“The motors used in the stamping machines purchased by the stamping workshop from Ji’er Machine Tool Factory need to be developed by BMW Motors. The motors used in the previous electric bicycles were also developed by BMW Motors.”< br>
“The development of various motors such as engine starter motors and air-conditioning compressor motors in our BMW cars is also handled by BMW Motors.”
“Now we have to develop the ones used in welding robots. As for the motor, I’m worried that they won’t be able to handle it.”
Although Jiang Hui provided him with ideas for a solution, Wang Feng was not so confident in the BMW motor.
Any of the above projects is enough for many scientific research institutes to work on seriously for several years.
No wonder Wang Fengfeng was worried that the BMW motor could not be handled properly.
“Many technologies of motors are interoperable. As long as we get a type of product, we can adapt to the needs of many occasions by adjusting the size.”
“I will personally take the motor with me when the time comes. The technical team will work together to solve technical problems."
Wang Feng naturally had no doubts when Jiang Hui said this.
People outside don't know how high Jiang Hui's technical level is, but the people inside BMW still know it very well.
No matter what type of technical problem it is, Jiang Hui can solve it easily.
The most important thing is that Jiang Hui can always cut in from some special places and provide everyone with a very effective solution that is in line with the current technical level.
To a certain extent, Jiang Hui deserves the greatest credit for the rapid development of BMW.
"Director, let me sort out the equipment needed to expand the production line and what bottleneck products are there, and I will give you an overall report then."
After Wang Feng said this, he left Jiang Hui's office.
In order to get the motor out as quickly as possible, Jiang Hui went directly to BMW Motors next door to confirm the situation with chief engineer Wu Wei.
“For engine starter motors, we can now produce products at the same level as our domestic counterparts, but there is still some distance from the technical parameters you specified before.”
“ Next In the next step, I plan to improve the overall performance of the motor from the aspects of copper wire winding and material performance improvement of silicon steel sheets.”
“We have already connected with Shougang for the project of improving the performance of silicon steel sheets. They are also very interested in this project.”
After Wu Wei was hired by BMW Motors, he has now dragged his family to work in Shencheng. All the technicians from the factory affiliated to Huazhong University of Science and Technology who were originally affiliated with the Huazhong University of Science and Technology have also come to Shenzhen. The remaining production plants have temporarily moved to Shenzhen. It is still retained and used to produce motors for BMW and other customers.
After arriving in Shencheng, Wu Wei felt like a fish in water. Without those constraints, he devoted himself almost wholeheartedly to the research and development of motor technology.
Jiang Hui’s support for BMW motors is also quite strong. He has purchased several advanced testing equipment from Japan and Europe to cooperate with the development of motors.
It can be said that although the current BMW motor is not very famous in China, its technical strength is not low at all.
Especially in the automobile industry, he will definitely be the king in the future.
"Shougang has a relatively deep technical background in silicon steel sheets. When I cooperated with them to develop high-strength steel plates for automobiles, the other party's enthusiasm was relatively high."
"But when we developed bearing steel later, , they are a bit complacent and have lost an opportunity.”
“I think they will pay attention to it if I ask them to make silicon steel sheets this time.”
Every steel factory in the country is now. It is state-owned.
BMW Electric can only choose the most suitable cooperation partners from these state-owned enterprises, and there are not many other choices in a short time.
Therefore, it is a relatively good plan to find Shougang, which we have cooperated with before.
"It is indeed as the director said, Shougang is more active this time, and now their chief engineer Zuo Guangsheng is in charge of this project."
"All walks of life in China The demand for motors is very large. As a high-end special steel, silicon steel sheets need The demand is certainly not small.”
“The key is that some key hydropower projects in the ministry also have relatively large requirements for the technical improvement of power generation units.”
“Projects in this area. Shougang and other manufacturers are also needed to improve the performance of silicon steel sheets.”
"To a certain extent, if the project Shougang cooperates with us is really successful, they can apply for other projects in the future, and the results will be produced soon."
< br>As a motor expert, Wu Wei naturally has a relatively in-depth understanding of the performance of silicon steel sheets, the main raw material for motors.
Motors have appeared a hundred years ago, and it has been difficult to make breakthrough changes or developments in some fundamental aspects.
The progress of various motor technologies often involves adjustments to some details and improvements little by little.
Or the performance of a certain material has changed significantly, resulting in a relatively large 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 loss, specifically..."
Since he wants to personally intervene in this project, Jiang Hui must come up with some specific improvement plans, or at least point out the specific direction of efforts for everyone.
Otherwise, it will be difficult to achieve a significant time saving effect.
“The heat treatment process of silicon steel sheets is a very critical process. High-temperature annealing of silicon steel sheets can eliminate internal stress and improve mechanical strength.”
“We can improve the temperature range Make some adjustments..."
Jiang Hui spent more than ten minutes explaining some of his ideas to Wu Wei.
...
While Jiang Hui and Wu Wei were improving AC motor technology, Shougang was not idle either.
“Lao Zuo, we must pay full attention to this cooperation with BMW Motors.”
“I heard a rumor that the relevant departments may restart the construction of the Three Gorges Dam. Discussion on the dam.”
“Although the results of the discussion are not so fast, it will still take a long time to officially start construction.”
"But for us, it will be a great achievement to use the past few years to improve the technology of silicon steel sheets. If we can provide silicon steel sheets to the hydropower generating units of the dam, it will definitely be a great achievement."
As Zhou Gang, the director of the Capital Steel Plant, being able to provide support for some large projects is definitely something that can show up in various summaries.
So many times, financial interests come second, and other fame and fortune are more important.
"Director, you can rest assured that we will go all out this time." "Jiang Hui worked with us to promote high-strength automotive steel plates many years ago. Now the high-strength BMW Light Steel plates are also provided by us.”
“It can be said that high-strength steel plates are already the steel type with the best profitability in our factory.”
“I feel that the future of silicon steel sheets will not be worse than automotive high-strength steel plates, but will only be better. Okay.”
“And silicon steel sheets are used in a wider range of applications, and are used in many key projects.”
“So no matter what aspect we consider, we will actively follow suit. Together with BMW Motors, we have developed a new generation of silicon steel sheets.”
As the chief engineer of the Capital Steel Plant, Zuo Guangsheng can be regarded as a steel industry professional with a relatively high technical level in China.
The more professionals you are, the more you will realize the importance of special steel plates.
China’s steel production is actually not very low.
In the past two years, some backward production capacities were even eliminated due to excessive production capacity.
However, compared with the overall output, in terms of advanced steel plates, Huaxia's output is relatively low.
With the rapid economic development, some special steel needs 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 definitely be much more comfortable to hold the technology of high-strength automobile steel sheets in one hand and the technology of silicon steel sheets in the other.
Even if we work in these two fields, we can still gain a firm foothold in the domestic steel industry.
“I heard from Baosteel that it will be put into production next year. They are also considering introducing automotive steel plate technology from Japan, which will definitely have a certain impact on the development of our high-strength automotive steel plates. ”
“At this time, we need to develop some advantageous steel types. ”
"Silicon steel sheets are a very good direction. Even if BMW Motors can provide us with limited help, we must continue the research and development work ourselves."
"The best thing is that both parties can work well together. Communicate and see if we can make some breakthroughs as soon as possible. "
Zhou Gang has 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 give full attention to it.
“I understand that the requirements for silicon steel sheets are different depending on the usage scenarios of the motor.”
“Whether it is the formula of the silicon steel sheets, the rolling thickness, or even the surface Heat treatment has different requirements. ”
"They should be able to provide some constructive suggestions regarding the silicon steel sheets that BMW Motors needs. I have already been communicating with Wu Wei, the chief engineer of BMW Motors."
"He is a well-known person in China. motor experts, some of their opinions are also very Constructive.”
“I will also visit and communicate in person to see if we can better promote this project.”
Zuo Guangsheng is very active. Now I have reported to Zhou Gang on the communication with BMW Motors.
It can be said that for the silicon steel sheet project, both Shougang and BMW Motors are highly motivated.
This is naturally very beneficial to the development of the project.
......
"Director, I heard that the BMW R&D Center is carrying out early development of CAD design software. I have seen from some papers that some foreign companies are also doing this. I am considering using computer technology to assist in some testing and development of motors. ”
“ There seems to be no manufacturer or school in China that has done specific work in this area.”
“I think the Electric Motors side can consider setting up a group for motor design and test software development, based on our past experience. Some experience, see if these things can be formed into a set of analysis and simulation software? ”
As a motor expert, Wu Wei is naturally aware of the huge impact that computer software may have on the 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 useful.
In particular, the development of industrial software is time-consuming and money-consuming.
The price of a computer is not cheap, and there are various other expenses.
In this era, various motor factories in China simply cannot even think about developing professional industrial software for motor design and testing.
That is to say, BMW Electric has a foreign investment background, and the person in charge, Jiang Hui, understands technology and values technology, especially things related to computer-aided design.
Furthermore, BMW Motors has no shortage of foreign exchange and has the opportunity to buy computers and other related auxiliary equipment from abroad.
Otherwise, if a certain condition is not met, this kind of project will not be possible.
“There is no problem. BMW Motors is determined to be the largest and most professional motor manufacturer in the country and even the world, and it must have some core things of its own.”
“Motor design and testing simulation related Industrial software can be turned into our core technology. As long as this thing is done well, the efficiency can be greatly improved when developing new products in the future.”
Whether you use it yourself or sell it to others in the future, developing industrial software is valuable.
Especially at this time, the global industrial software market is actually just getting started.
Even if other manufacturers started research very early in the past, the progress was actually just like that. After all, computer technology was too backward before, and it has only been in the past few years that rapid changes have occurred.
So 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 too early.
Wu Wei originally thought that he would have to spend a little money to convince Jiang Hui.
After all, according to his estimate, if BMW Motors really develops its own motor design and test simulation software, the final investment will definitely be more than one million yuan.
In 1984, an investment of this magnitude was no longer small.
Besides, this is just the start-up capital. He doesn't know how long it will take to actually develop software that can be used effectively.
Maybe more 1 million will be needed in the future to get results.
"Okay, I will submit a formal project plan next week!"
Jiang Hui agreed so happily today, Wu Wei must hurry up and implement the project.
To avoid long nights and many dreams.
