Chapter 304 Academic leaders must rely on technology to achieve success
"Everyone has their own pursuits, and Professor Wu is no exception."

"He will not easily agree to leave Huazhong Science and Technology. He must have some concerns and worries."

"We will solve whatever the other party is worried about."

"As long as the conditions are attractive enough, there will be no one that cannot be poached."

It’s not like Wu Wei has to leave China to live abroad. Jiang Hui feels that there must be a way to get him to work at BMW Motors.

The position of chief engineer is worthy of his status as a professor.

Although BMW Motor is not particularly well-known yet and does not have any actual technology or factory facilities, its future is still worth looking forward to with the support of BMW technology.

"As one of the last batch of genuine college students in the 1960s, Wu Wei is only 40 years old this year. He must hope to achieve certain academic success."

"As for his concerns and worries, according to preliminary investigations, they are probably about his wife and children's work and studies."

"The other thing is that I'm definitely worried that after I go to a company, I won't be able to simply engage in technical research."

Fang Huihui quickly summarized the information she had learned.

She could handle some of the content, but some things were more mysterious and she was not sure whether she could meet the other party's requirements.

"For the children's schooling, we can coordinate with the best school in Shenzhen, or they can go directly to Hong Kong."

"It's easier to arrange a job for his wife, whether it's BMW Motors or BMW Cars, or even BMW Technology Headquarters."

“As for academic pursuits, this is actually not that difficult.”

"Please arrange it. I will personally discuss the professional technology of motors with him and let him know that our BMW motors also have technical background."

"Now that we have acquired the motor factory run by Huazhong University of Science and Technology, we will also reorganize it. In the early stage, Wu Wei can continue to help manage the factory in Qingcheng."

"After the factory and R&D center in Shenzhen are built, he will come to work."

BMW Technology's business will certainly expand, and Jiang Hui cannot rely solely on himself to develop each business.

Jiang Hui attaches great importance to BMW Motors as an important part of improving the automotive parts and even equipment industry.

Jiang Hui finally found a suitable technical leader and didn't want to miss it.

"It would be best if you could go directly and talk to Professor Wu."

"I'll have someone book a plane ticket to Qingcheng tomorrow."

Fang Huihui is also very optimistic about Wu Wei's technical level. The company can poach him, and she is even more optimistic about the future of BMW Motors.

Jiang Hui also attached great importance to this trip to Qingcheng and specially prepared a set of information to take with him.

After all, to win over an electrical engineering academic leader like Wu Wei, you still have to rely on advanced technology.

Talking about technology with these people is more attractive than talking about any benefits.

The prerequisite is that the technology you propose is truly advanced.

Accompanied by Fang Huihui, Jiang Hui met Wu Wei very smoothly.

Since there had been some communication over the phone in advance, Wu Wei had a preliminary understanding of Jiang Hui's purpose.

"Director Jiang, I've heard of your name for a long time. When I was communicating with the people from Second Automobile Works before, they specifically mentioned the 4MT manual transmission and the new BJ212 that you were responsible for designing."

"Later, the First Machine Industry Ministry promoted the reform of Chaoyang Motorcycle Factory, which brought us a great surprise."

Jiang Hui originally thought that Wu Wei was a rather dull professor who only cared about academic matters.

When we met, we found that the situation did not seem to be the case.

The other party actually greeted him quite enthusiastically.

Of course, Jiang Hui’s past achievements probably also played a role.

In Wu Wei's opinion, Jiang Hui is also a high-level talent who has mastered core technologies, and is half the same kind as himself.

"Professor Wu, you are a well-known expert in the motor industry. You have a great influence in motor research in many fields such as automotive motors and generators."

"The domestic brushless motor technology has been significantly improved because of you."

When it comes to business compliments, Jiang Hui is definitely no worse than Wu Wei.

However, Wu Wei was still too thin-skinned. When he heard Jiang Hui praising him about brushless motors, he immediately felt a little embarrassed.

"It is a shame that the technology of domestic brushless motors, especially DC brushless motors, is still far behind the international advanced level."

"I have read about some foreign research technologies in some academic journals. ABB, Toei Electric, Minebea, Johnson Electric and other companies have truly advanced technologies in this area."

When it comes to professional fields, Wu Wei is still very interested.

Although the motor seems to be just an ordinary product, it has too many application scenarios and technical categories.

It would take up all a person's energy to study motors professionally throughout his life.

"We are a company in Hong Kong, and we have also done some research on brushless DC motors. Today, I have the opportunity to discuss this with you, Professor Wu."

As Jiang Hui spoke, he took out a few drawings from his bag.

"There are various types of motors, and I think the brushless DC motor will be the most ideal speed-regulating motor in the future."

"It combines the advantages of DC motors and AC motors. It has the good adjustment performance of DC motors, and the advantages of AC motors such as simple structure, no commutation sparks, reliable operation and easy maintenance."

"These features are destined to be well received by the market and can be widely used in the fields of automobiles, home appliances, industrial equipment, etc."

Hearing Jiang Hui's affirmation of his main research direction, Wu Wei also became interested. "The brushless DC motor is indeed very special. It consists of a motor body and a driver. Different from a brushed DC motor, a brushless DC motor does not use a mechanical brush device, but a square wave self-controlled permanent magnet synchronous motor. It uses a Hall sensor instead of a carbon brush commutator and uses neodymium iron boron as the permanent magnet material of the rotor."

"In 1955, Americans first applied for a patent to replace the mechanical brushes of brushed DC motors with transistor commutation circuits, officially marking the birth of modern brushless DC motors."

"But at that time, there was no device to detect the motor rotor position, and the motor had no starting capability."

When Fang Huihui saw that Wu Wei and Jiang Hui were already happily communicating, she immediately became a nobody beside them.

"Since the 70s, 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 and their capacity has continued to increase."

"Especially with the launch of the Mac Classic brushless DC motor and its driver in 1978, and the development of square wave brushless motors and sine wave brushless DC motors, brushless motors really began to enter the practical stage and developed rapidly."

"The brushless DC motor that we are developing at BMW Motor is mainly composed of a rotor made of permanent magnet material, a stator with coil windings, and a position sensor..."

Jiang Hui wants to rely on technology to attract Wu Wei today, so naturally he has to come up with some practical stuff.

Wu Wei is very capable and his research direction is correct, but the cutting-edge technologies he can access are limited.

To put it bluntly, he lacks someone to give him some guidance.

Jiang Hui, a half-baked motor expert, may not be able to do better than Wu Wei if he studies motors himself, but he is much better than Wu Wei in guiding the future development direction and some major design structures.

When the two are combined, the effect of one plus one being greater than two can definitely be achieved.

"Have you already achieved any concrete research results?"

When Wu Wei looked at the drawings that Jiang Hui showed him, his eyes looked a little different.

He is considered to be one of the people in China who has conducted in-depth research on brushless DC motors, but brushed DC motor technology is more mature, has a faster starting response speed, greater starting torque, smoother operation, and higher control accuracy.

In addition, the DC brush motor has a simple structure and is easy to produce and process. It has been widely used in the 19th century and its technology is relatively mature. It is currently the mainstream in China.

However, brushless DC motor technology is relatively immature, and many companies are still in the research stage and have not put it into commercial use.

"That's right, but this is just a forward-looking research product. To realize its design, we still need to design a complex control circuit. Problems in this area will take some time to solve."

"In the short term, we will also conduct research on brushed DC motors and AC motors at the same time."

"BMW Motor's goal is to become the world's most technologically advanced motor manufacturer, with products covering all types of motors."

At this time, it is natural to paint a big picture appropriately.

Regardless of whether Wu Wei believes it or not, at least he should give people hope.

“The DC brushed 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 brushed DC motors have greater output power and higher control accuracy, which can reach 0.01 mm, and can almost stop moving parts wherever they are desired, so all precision machine tools use brushed DC motors for control accuracy."

"Both products are worth studying carefully, and it would be a pity to give up on them."

The brushless DC motor is not the earliest product, but was developed based on the brushed motor. Its structure is more complex than that of the brushed motor.

As a scholar who has conducted in-depth research on brushless DC motors, Wu Wei has naturally also done more research on brushed DC motors.

Now, hearing that BMW Motor is preparing to make efforts in both fields and has set such ambitious goals, my mood immediately changes.

Ever since Fang Huihui revealed her intention to invite him to work at BMW Motor, he specifically went to investigate and learn about the situation of BMW Motor and even companies such as BMW Technology and BMW Automobile.

He knew that these were among the foreign-funded enterprises with the best treatment in the country.

Especially some information about BMW cars, he can get a lot of information by just asking around.

It is no secret that Chaoyang Motorcycle Manufacturing Factory paid out bonuses for four months last year.

"Professor Wu, as a Hong Kong enterprise, we can import various advanced equipment and instruments from overseas, which is very meaningful for motor research."

"The results you can achieve in the same amount of time at school and at BMW Motors are completely different."

"You are now at the best age to demonstrate your professional skills, but I think it will take at least a dozen years for domestic universities to improve their experimental equipment quickly."

"After a dozen years, the daylily will be cold."

Jiang Hui began to shift the topic to job hopping.

His time was also precious, and he couldn't stay in Qingcheng for too long.

At this age, the level of China's chip and electronic component industry is still far behind that of foreign countries.

However, in many aspects such as the availability of products, the difference is not that big.

By 1971, China had developed the country's first photolithography machine and step-and-repeat camera, and put them into large-scale production for use in 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 technological gap and was put into mass production and put into use.

This is China's second-generation lithography machine.

This achievement won the first prize of the capital city's first scientific and technological achievement in 1981.

Until later generations, only a few countries in the world, such as America and Japan, could manufacture this 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 at Yenching University completed three technical solutions and produced China's first 109-bit dynamic random access memory at the then CAS Factory 1024.

Although this achievement was four or five years later than that of America and Japan, it was four or five years earlier than that of Goryeo.

You know, both Korea and Taiwan only started to introduce their own wafer production lines from America in the past few years, so this gap can definitely be caught up.

Samsung Electronics and TSMC, which later became very powerful in the chip field, are still weaklings now and have not even officially changed their names.

Through the research on brushless DC motors, Jiang Hui began to enter the semiconductor field using motor controllers as a starting point. This is something that Jiang Hui cares about very much.

Others may not know the importance of chips, but how could he not know?

There are more than 600 semiconductor production factories across 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 taken some actions.

In October 1982, in order to strengthen the leadership of the national computer and large-scale integrated circuit industry, the relevant departments established the "Electronic Computer and Large-Scale Integrated Circuit Leadership Group" with senior leaders as group leaders, formulated the China Chip Development Plan, and proposed to carry out technological transformation of the semiconductor industry during the "Sixth Five-Year Plan" (10-1981).

It’s just that the semiconductor industry requires relatively large investments, and many domestic industries need funds for development, so ultimately there is only a certain inclination towards the military industry, and the development speed of civilian semiconductor technology is far slower than that overseas.

Some industries that originally had technological advantages were also quickly surpassed by companies from other countries such as Korea.

"Director Jiang, what you said makes sense, but to develop advanced motor technology, we need the support of multiple departments such as the First and Fourth Machine Ministries, and even the Ministry of Metallurgy. Otherwise, it will be very difficult to rely solely on BMW Motors."

Wu Wei was already a little tempted.

From his communication with Jiang Hui, he had already been attracted.

"I will personally coordinate with the ministry."

"The technical background of our BMW Motor is not limited to what we just discussed."

"As long as Professor Wu can bring your team to join BMW Motor, I am confident that we will be able to develop and produce the most advanced DC brushless motor in China and with world-class standards next year."

"The year after next, we will start mass production of brushless DC motors."

"As for the various treatments your team will receive after arriving at BMW Motor, you don't need to worry at all. We will definitely not let you down!"

Jiang Hui had already said this, so Wu Wei didn't bother to be polite anymore. "I'll talk to the school and give you a formal reply within three days!"
