Ma Weiming: "Chinese Pride" in the Electrical Industry

He was a 34-year-old professor and he was promoted to become a doctoral tutor at the age of 38. He was elected the youngest academician of the Chinese Academy of Engineering at the age of 41, and was promoted to the rank of major general of the Navy at the age of 42.

He first put forward the theory of “power integration” in the world, he has tackled nearly a thousand major technical difficulties that restrict the development of equipment, and has more than 20 achievements as “world first” and “internationally leading”;

He is Professor Ma Weiming of Naval University of Engineering.

The "Chinese Heart" of New Type Battleships

Some people vividly compare the power system to the "heart" of modern ships. In the past, my submarine motor equipment mainly relied on imports, which severely restricted the construction of naval combat capabilities. In that year, a certain type of main submarine's charging generator suddenly failed, causing the submarines to completely stop and the troops were up and down. Ma Weiming heard that Starry Night found the head of the navy and said: "Please give this task to me!" In the Spring Festival, Ma Weiming and his colleagues gave up their vacation. On the second day of the Lunar New Year, Ma Weiming was sent to the hospital due to fatigue. Others are in the hospital, their hearts are hung with research progress, and they sneak back to the lab every day after they finish. After dozens of repeated experiments day and night and nearly a thousand times, a set of detailed technical reform measures were sent to the higher authorities along with the analysis report of the entire accident. The three-month submarine of “Luo Wo” was re-started. "In order to be unrestrained, the core technology must be made domestically. Otherwise, we can only live on the waistband of others," Ma Weiming said firmly. After research and demonstration, he took the lead in putting forward the technical idea of ​​power integration in the world, that is, using a single motor to simultaneously send both AC and DC power. At that time, the motor industry at home and abroad believed that it was impossible to achieve "delusion."

However, Ma Weiming, who is "tempered", does not believe in evil. After ten years of hard work, he successfully developed the world's first AC and DC dual-winding generator system, and in 2002 formally produced equipment troops. Since then, our new navy submarine has had a strong “Chinese heart”. In the midsummer, the Ministry of Science and Technology fieldwork concluded that many years of practice have proved that this AC-DC hybrid power supply system not only has high power density and reliability, but also occupies a small volume and has significant military and economic benefits. After rigorous review, this achievement has been officially confirmed as the 2010 National Science and Technology Progress Award.

The "China Authority" in the Power World

Ma Weiming has a maverick personality, which is to respect science, not respect foreign affairs, and not superstitious authority. A few years ago, there was a major failure in the introduction of a large generator system from E in China. As the chief expert of the Chinese side, Ma Weiming participates in negotiations with the E country delegation. After a site investigation, he and his colleagues quickly found the crux of the problem: the generator was congenitally deficient, and the responsibility was entirely on the E side. Negotiations have just begun. The delegation of the United Nations has denied it and accused China of violating the operating procedures. They also proudly took out a drawing and said sternly, "Sir, this is our design drawing. Everything you said is only a subjective judgment!" What made the representative of E country never dreamed was that Prior to the negotiations, Ma Weiming and his colleagues had obtained several core simulation data after several simulation tests and plotted the design drawings. When Ma Weiming placed the 10 times bigger picture than the E side on the negotiating table, 10 senior motor experts from Country E immediately stunned. But they still bluntly reasoned: "Your theory is too bizarre, we do not understand!" "Sir, we are talking about science!" Ma Weiming pointed to the drawing and shouted, "You don't understand, I can teach you!" The translator was stunned by this lion-like roar and looked at Ma Weiming for a long time and could not open his mouth. "Let's translate!" Ma Weiming screamed: "Additionally, I won't pay for it, teach it for free!"

This time, the E personnel obviously understood. In the face of evidence, they had to bow their heads. "On the frontier of scientific research, as long as it is Ma Weiming's sighted subject, he will have to embark on a difficult journey." Zhang Xiaofeng, Ma Weiming's old partner and a deputy director of Naval University of Engineering, said: "A few years ago, he aimed A cutting-edge technology in the field of international science and technology, applied for 1 million yuan to demonstrate funding, but after the completion of the demonstration report, the follow-up funds did not keep up in time. Ma Weiming has come swiftly, he said, “The pots must be sold iron!” He from his own research In the accumulation of funds, 20 million yuan was collected, leading a group of young experts in the laboratory to work hard for two years and successfully developed a small prototype.” This is a research project that has not been successfully researched for over 20 years in a world technological power.

Innovation Kingdom "Made in China"

Ma Weiming is a person who puts "national interests" above his head. For a long time, core technologies such as wind power converters have been monopolized by several large foreign companies. Two years ago, the equipment they sold to China was a one-off price: a set of 2.3 million yuan. After learning from cooperation with Xiangtan Motor Factory, Ma Weiming was determined to use technology accumulation and team strength for many years to break foreign technology monopoly. They spent more than two years and successfully developed a 2 megawatt permanent-magnet direct-drive wind turbine converter with independent intellectual property rights. Subsequently, three-megawatt and five-megawatt wind power inverters were successively developed...

The Chinese successfully developed high-power wind turbine converters! This news immediately caused a strong reaction in the world. In that year, the price of converters exported from foreign countries to China dropped to 980,000 yuan each. "Inherent oscillation" is a worldwide problem that puzzles the motor industry. During the first technical negotiations on the introduction of the power supply system of a certain country's M company by a new generation of submarines of our army, Ma Weiming once raised this issue in good faith, but the other party dismissed it at the time. “Then do it yourself!” After more than 1800 days and nights, Ma Weiming and his team successfully invented a multi-phase rectifier generator with stable windings, which fundamentally solved the “natural oscillation” as a worldwide problem. After knowing that the chief expert of M company wanted to trade privately with Ma Weiming: "You can use your patent to help us solve the problem of oscillation. We are willing to pay you the equivalent of RMB 1.5 million in cash in your country as a reward." 1.5 million yuan, Indeed, there is a strong temptation, but Ma Weiming said: "Patented technology is a service invention. It belongs not only to me but also to my country!"

The "China Model" of Talent Cultivation

From a research team with only 5 members to a 65-person research institute, it has grown from a laboratory with assets of less than 10,000 yuan to a national defense science and technology key laboratory with billions of assets and advanced technology. The research direction has developed into an innovation research center and a high-level talents cultivation base for the integrated power technology field in China's warships. Ma Weiming has devoted himself to fostering China's naval ship's electric technical talents.

With regard to the Ph.D.'s concern for the work of the tutors in the current society, Ma Weiming laughs at the team's migrant workers. In order to create opportunities for young people, he not only gives thoughts and funds but also gives them questions. Most of these issues come from Ma Weiming's innovative thinking. In the past 10 years, he has never signed his scientific research achievement led by the award, leaving the opportunity to the young people. From here, there have been 6 postdoctoral fellows, 70 doctors, and 116 masters. For talented people, Ma Weiming has his own view: "To cultivate talents, I don't hurry to look at temporary successes or failures. As long as you work hard, even if the outcome is a failure, I will still give you a high score and use your efforts to give You set a job allowance.” After Zhao Zhihua was transferred to the team, Ma Weiming invested more than 10 million yuan for him. However, during the first three years, Zhao Zhihua did not come up with a topic. Some people began to think that this young man might not work. In the fourth year, Zhao Zhihua published his first paper and immediately caused a sensation in the international community. He has now grown to be the chief expert in the research direction of laboratory electromagnetic compatibility.

In the eyes of Ma Weiming, engaging in technological innovation must be extended to engineering practice, and a mature product is considered successful. Therefore, he particularly emphasized the practical ability of the research team. From him, from drawing to manufacturing, each prototype of the 1:1 prototype was created by masters and doctors who participated personally in the first line, working hand in hand with the workers' masters. In recent years, Ma Weiming led his team and has undertaken more than 40 major scientific research projects. Their innovative theories and leading technologies have won praises and applause for the army and the motherland.
