Chapter 304 Academic leaders must rely on technology
“Everyone has some pursuits of their own, and Professor Wu is no exception.”
“He will not easily agree to leave. Huazhong Technology must also have some concerns and worries.”
“We will solve whatever the other party is worried about.”
“As long as we provide attractive enough conditions, there is no way we can’t dig it. "
It's not like Wu Wei was asked to leave China and live abroad. Jiang Hui felt that there must be a way to get him to work at BMW Electric.
The position of chief engineer is worthy of his status as a professor.
Although BMW Motors is not particularly well-known yet and does not have any actual technology or factory buildings, its future is still worth looking forward to thanks to BMW technology.
"Wu Wei, as one of the last genuine college students in the 1960s, is only 40 years old this year. He definitely hopes that he will achieve certain academic achievements."
"As for worries and Worrying, according to the preliminary investigation, it should still be about the work and study of his wife and children.”
"In addition, I am definitely worried that after joining the enterprise, I will not be able to simply engage in technical research."
Fang Huihui quickly summarized the information she learned.
She has a way to handle some content, but some things are more mysterious, and she is not sure whether she can meet the other party's requirements.
“For the children’s schooling, we can coordinate with the best school in Shenzhen, or we can go directly to Hong Kong City to go to school.”
“His wife’s work will be better arranged. No matter it’s BMW Motors, BMW cars, or even BMW Technology Headquarters, we can arrange it.”
"As for academic pursuits, this is actually not that difficult."
"You can arrange it, and I will personally go and communicate with him about motor expertise and let him know that our BMW motors also have technical background. ”
“After acquiring the school-run electrical machinery factory of Huazhong University of Science and Technology, it will also be re-integrated. In the initial stage, Wu Wei can continue to assist in managing the factory in Qingcheng.”
“Waiting. After the factories and R&D centers in Shencheng are built, he will come to work. "
BMW Technology's stall will definitely become bigger and bigger, and Jiang Hui cannot develop various enterprises entirely on his own.
As an important part of improving the auto parts and even equipment industry, Jiang Hui still attaches great importance to BMW motors.
After finally meeting a suitable technical leader, Jiang Hui didn’t want to miss it.
"It would be best if you could go directly and communicate with Professor Wu."
"I will have someone book a plane ticket to Qingcheng tomorrow in a moment."< br>
Fang Huihui is also very optimistic about Wu Wei's technical level. The company can poach him. She is even more optimistic about the future of BMW Motors.
Jiang Hui also attached great importance to this trip to Qingcheng and specially compiled a piece of information to take with him.
After all, to get a leader in electrical engineering like Wu Wei, we still have to rely on advanced technology.
Talking about technology with these people is more attractive than talking about any welfare benefits.
The premise is that the technology you propose is really advanced.
With Fang Huihui accompanying him, Jiang Hui met Wu Wei smoothly.
Due to some communication in advance on the phone, Wu Wei had a preliminary understanding of Jiang Hui's intention.
"Director Jiang, I have heard about this name for a long time. When I communicated with people from Second Automobile Works before, they specifically mentioned the 4MT manual transmission and the new BJ212 that you are responsible for designing."
"Later The First Ministry of Machinery promoted the reform of Chaoyang Motorcycle Manufacturing Factory, which brought a big surprise to everyone. "
Jiang Hui originally thought that Wu Wei was a relatively dull professor who only knew about academics.
At this meeting, I found that the situation did not seem to be like this.
The other party actually started chatting with him enthusiastically.
Of course, some of Jiang Hui's past achievements may have played a role.
In Wu Wei's view, Jiang Hui can be regarded as a high-level talent who has mastered core technologies, and he is half the same person as him.
"Professor Wu, you are a well-known expert in the motor industry, and you are also very influential in motor research in many fields such as automobile motors and generators."
"Domestic Brushless motor technology has been significantly improved because of your presence.”
In terms of business competition, Jiang Hui is definitely no worse than Wu Wei.
However, Wu Wei is still too thin-skinned. Hearing Jiang Hui praise him about brushless motors, he immediately felt a little embarrassed.
“I am ashamed to say that there is still a big gap between the technology of domestic brushless motors, especially brushless DC motors, and the international advanced level.”
“I read it from some academic magazines I have visited some foreign research technologies, and the technologies of ABB, Dongying Electric, Minebea, Johnson Electric and other companies are truly advanced in this area.”
When it comes to professional fields, Wu Wei’s. The interest is still very high.
Even though the motor seems to be just an ordinary product, it has too many application scenarios and technical categories.
Being able to study motors professionally throughout a lifetime is enough to spend all one's energy.
“We, BMW Motors, are a company based in Hong Kong. We have also done some research on brushless DC motors. It’s just a good time to communicate with you, Professor Wu, today.”
Jiang Hui said, While taking out a few drawings from the bag.
“There are various types of motors, and I think brushless DC motors will be the most ideal speed-controlled motors in the future.”
"It combines the advantages of DC motors and AC motors. It not only has the good adjustment performance of DC motors, but also has the advantages of AC motors such as simple structure, no commutation sparks, reliable operation and easy maintenance."
" These features are destined to be popular in the market and can be widely used in automobiles, home appliances, industrial equipment and other fields.”
Wu Wei also became interested when Jiang Hui confirmed his main research direction, “DC. The brushless motor is indeed very special. It consists of the motor body and the driver. It is different from the brushed DC motor. The brushless DC motor does not use a mechanical brush device, but uses a square wave self-controlled permanent magnet synchronous motor, and uses a synchronous motor. The sensor replaces the carbon brush commutator and uses NdFeB as the permanent magnet material of the rotor. "
"In 1955, people in the United States applied for the first time to use transistor commutation lines to replace the mechanical brushes of brushed DC motors. The patent officially marked the birth of the modern brushless DC motor. "But there was no motor rotor position detection device at that time, and the motor had no starting capability."
When Fang Huihui saw that Wu Wei and Jiang Hui were communicating happily, she immediately became a little transparent next to them.
“Since the 1970s, with the emergence of new power semiconductor devices such as GTR and MOSFET, the rapid development of computer control technology, and the advent of high-performance rare earth permanent magnet materials, brushless DC motors have developed rapidly. The capacity continues to increase. ”
“Especially with the introduction of the mac classic brushless DC motor and its driver in 1978, as well as the development of square wave brushless motors and sine wave brushless DC motors, brushless motors. It has really begun to enter the practical stage and is developing rapidly.”
“The brushless DC motor we are developing at BMW Motors mainly consists of a rotor made of permanent magnet materials, a stator with coil windings and a rotor. Position sensor composition..."
Jiang Hui wanted to rely on technology to attract Wu Wei today, so naturally he had to come up with some useful information.
Wu Wei is very capable and has the right research direction, but the cutting-edge technologies he has access to are relatively limited.
To put it bluntly, he lacks someone to nudge him a little bit.
As for Jiang Hui, a "half-full" motor expert, if he studies motors by himself, he may not necessarily be able to do better than Wu Wei. But in terms of guiding future development directions and some large design structures, he is much better than Wu Wei.
When the two are combined, one plus one can definitely play a greater role than two.
"Do you already have specific research results?"
Wu Wei looked at the drawings displayed by Jiang Hui, and his eyes were a little different.
He is one of the people in China who has studied brushless DC motors more deeply, but brushed DC motor technology is more mature, has faster starting response, larger starting torque, smoother operation and higher control accuracy.
Furthermore, the DC brush motor has a simple mechanism and is easy to produce and process. It has been widely used in the 19th century. The technology development is relatively mature, and it is currently the mainstream in China.
The brushless DC motor technology is relatively immature, and many companies are still in a state of research and have not put it into commercial use.
"Yes, but this is just a forward-looking research product. To realize its design, we need to design complex control circuits. This problem will take a certain amount of time to solve."
"In the short term, we Research work on DC brushed motors and AC motors will also be carried out at the same time.”
“BMW Motor’s goal is to be the most technologically advanced motor manufacturer in the world, with products covering various motor types.”
At this time, it is natural to draw a picture of the pie appropriately.
Whether Wu Wei believes it or not, at least we should give people something to look forward to.
"The DC brush motor has a fast starting response speed, large starting torque, and smooth speed change, while the brushless motor has a large starting resistance and a relatively small starting torque."
"But the DC brush motor has a greater output power and control The accuracy is higher, the control accuracy can reach 0.01 mm, and the moving parts can be stopped almost anywhere you want, so all precision machine tools use DC brush motors to control the accuracy."
"These two. The products are all worthy of careful study, and it would be a pity to give up.”
The brushless DC motor is not the earliest product, but is developed on the basis of brushed motors, and its structure is smaller than that of brushed motors. Brushed motors have a complex structure.
Wu Wei, as a scholar who has studied brushless DC motors in depth, has naturally done a lot of research on brushed DC motors.
Now that I heard that BMW Motors is preparing to make efforts in these two fields and has set such ambitious goals, my mood immediately changed.
Since Fang Huihui revealed her intention to invite him to work at BMW Electric, he also went to investigate and understand the situation of BMW Electric and even BMW Technology and BMW Automobile and other companies.
He knows that this is a group of foreign-funded enterprises with the best treatment in China.
Especially some information about BMW cars, he can get a lot of content by just asking around.
It is no secret that Chaoyang Motorcycle Manufacturing Factory paid bonuses for four months last year.
"Professor Wu, as a port city enterprise, our BMW Motor can import various advanced equipment and instruments from overseas, which is very meaningful for the research of motors."
"Under the same time situation, The results you can research in school and at our BMW Motor are completely different.”
“You are now at the age where you can best demonstrate your professional and technical skills, and the experimental equipment of domestic universities needs to be improved rapidly. , I think it will take at least ten years."
"After more than ten years, the day lily will be cold."
Jiang Hui began to shift the topic to job-hopping.
His time is also precious, and he cannot stay in Qingcheng for too long.
In this era, China's chip and electronic components industry is certainly far behind in level compared to foreign countries.
But in many aspects such as the availability of products, the difference is not that big.
In 1971, Huaxia had developed the first domestic photolithography machine and step-and-repeat camera and put them into large-scale production for use by the national semiconductor industry.
This achievement won the National Science and Technology Conference Award in 1978.
In 1980, Professor Xu's team at Huaqing University completed the development of the country's first "automatic alignment step-by-step projection lithography machine", which could process the thinnest line width of 0.8 microns, filling the domestic technology gap, and put it into mass production and delivery use.
This is China’s second generation lithography machine.
This achievement won the first prize of the first Science and Technology Achievement Award of the Capital City in 1981.
Until later generations, only a few countries in the world, such as the United States and Japan, could manufacture this kind of equipment.
It is worth mentioning that in 1975, China had completed the research and development of the core technology of dynamic random access memory.
The Semiconductor Teaching and Research Section of the Department of Physics of Yenching University completed three technical solutions and produced China's first 1024-bit dynamic random access memory at the then 109 Factory of the Chinese Academy of Sciences.
Although this achievement was four or five years later than the United States and Japan, it was four or five years earlier than Korea.
You know, whether it is Korea or Baodao, which only started to introduce its own wafer production lines from the United States in the past few years, this gap can be caught up.
Samsung Electronics and TSMC, which were very powerful in the chip field in later generations, are still weaklings and have not even officially changed their names.
Through the research on brushless DC motors, Jiang Hui is very concerned about entering the semiconductor field from motor controllers.
If others don't know the importance of chips, how can he know it?
There are more than 600 semiconductor production factories in China, and the total amount of integrated circuits they produce in a year is only one-tenth of the monthly output of a large factory in Japan.
This situation must be broken.
In order to change this situation, the country has not taken any action at all.
In October 1982, in order to strengthen the leadership of the national computer and large-scale integrated circuit industry, relevant departments established the "Electronic Computer and Large-Scale Integrated Circuit Leading Group" headed by senior leaders, and formulated the Huaxia The chip development plan proposes technological transformation of the semiconductor industry during the "Sixth Five-Year Plan" (1981-1985).
It's just that the investment in the semiconductor industry is relatively large, and many domestic industries need funds to develop. In the end, there is only a certain tilt in the military industry, and the development speed of civilian semiconductor technology is far slower than overseas.
Some industries that originally had technological advantages were quickly surpassed by companies from Korea and other countries.
"Director Jiang, what you said makes sense, but to develop advanced motor technology, we need the support of the First Machinery Department, the Fourth Machinery Department, and even the Metallurgical Department and other departments. Otherwise, it would be very difficult to rely on BMW motors alone.”
Wu Wei is already a little excited.
From the exchange with Jiang Hui, he was already moved.
"I will personally coordinate with the ministries and commissions."
"Our BMW Motor's own technical background is not just the ones we just communicated with."
"As long as Professor Wu can bring it with him, With your team joining BMW Motors, I am confident that next year we will develop and produce the most advanced DC brushed motors in the country with world-class standards.”
“The next year, we will start to make DC brushless motors. The motor has entered mass production.”
“As for the various treatments your team will receive after arriving at BMW Motors, you don’t need to worry at all. It will definitely not make you feel cold!”
Jiang Hui has already said this, and Wu Wei is not holding on, "I'll communicate with the school and give you a formal reply within three days!"
