In an interview, Wang Yuxing described the weight of the team in his heart: "The reason why Mount Everest is Mount Everest is because it is on the Himalayas-without the power of enterprises and teams, individuals cannot do things."

This is what he said and did. On November 26, 2022, when he organized and participated in the successful development of the 19 MW semi-direct drive permanent magnet wind turbine, in the face of praise and recognition from leaders and colleagues, he sincerely said that the success of the project "is by no means my personal credit, without the efforts of colleagues in design, technology, business department and other departments, this project cannot be achieved".

Since entering Fenxi Heavy Industry in 2007, Wang Yuxing has successively served as wind power test technician, director of the motor unit room, deputy manager of the technical department of the motor division, deputy director of the motor research institute, and director of the special motor research institute. Director of the Motor Technology Center of West Heavy Industry Motor Co., Ltd. In his own words, embarking on the road of motor research and development "at the beginning was to obey the needs of the organization", and later it was driven by the sense of mission of "making contributions to the independent and controllable technology" and "experienced a process of understanding".

To engage in research, to ask more questions to the market

When it comes to motor technology, Wang Yuxing is like a treasure. He said that as soon as he entered the factory, he caught up with the good era of generator development: in 2008, Fenxi heavy Industry responded to the national new energy policy call to accelerate the construction of a safe, efficient, clean and low-carbon energy system, began to transform from marine motors to develop wind turbines, introduced 2 MW doubly-fed asynchronous wind turbine technology from German LDW Company, and successively developed multi-type wind turbine products through absorption and transformation.

It was at this time that Wang Yuxing began to focus on the forefront of wind power generator technology: "I am the kind of person who will either quit or do it as well as possible-since the organization needs it, it is necessary to work towards the most cutting-edge technology in this field." In his view, the current mainstream wind turbine technology is relatively mature, and it is basically close to the critical value of existing products. "There is not a big gap in the technical capabilities of mainstream manufacturers." Press the critical value of materials and technology to make products quickly and well ", and the second is to rely on refined design," use the accumulation of experience to be professional in subdivided fields ".

Wang Yuxing said that the generator market is very rolling, but this is not necessarily a bad thing, because it will force the team to calm down and face the market and really revolve around the needs of customers. In his team, researchers must meet customers and talk about their needs together with the sales department. It is even more a "necessary skill" to sit down with customers regularly and hold small meetings for technical discussions ". "Ask people what they want and then do research instead of flying. Only in this way can the cost of a series of work such as research and development really come down."

"Anyone in our line of work knows that the motor itself has limited room for cost reduction," said Wang Yuxing, "but if you can do adequate communication with your customers to understand their technical requirements, resources and application scenarios, then you can customize the design in a targeted manner to achieve further cost control. This 'one cent and a dime, 'is actually 'stout' from here."

"Our business is highly market-oriented and the competition is fierce. Those who engage in research should not squat in the study, but should ask more questions from the market and consult customers." He concluded.

"Boutique" and "mediocre", the gap is in the details

From the semi-direct drive permanent magnet wind turbine, which has set a new global single-unit capacity record, to the first set of marine low-speed through-shaft permanent magnet shaft generator in China, Wang Yuxing's team has achieved enough achievements in recent years to make most of its peers envy. However, in his view, the emphasis on R & D is to endure loneliness, accumulate inheritance, and innovate in details. "Don't be complacent and engage in the" almost got "set-especially when you are at the top level in the industry. You should be more practical and cautious."

What he thought in his mind was "how to make what is not available and make what is already better". In his view, as far as the motor products currently involved in this team are concerned, it is easy to achieve if the goal is to meet the basic needs of customers. The difficulty lies in how to approach the limits of materials, design and cost, and meet the higher requirements of customers with lower cost under the premise of ensuring quality. This requires the improvement of a series of capabilities such as design methods and design accuracy, "related to our accumulation, so we can't be anxious".

"It sounds greedy, but I think there is no greed in research and development. I have to dare to think." He said with a smile.

Wang Yuxing feels that most of the mainstream technologies and applied materials on the market "have not yet approached this limit and boundary". A large part of his daily thinking is how to approach the "boundary".

Fenxi Heavy Industry's atmosphere of excellence infected him. He feels that there is not a big technical gap between "high-quality products" and "mediocre products", and the key to success or failure is often in details. He has an extreme pursuit of detail.

When formulating the design scheme of 19 MW semi-direct drive permanent magnet wind turbine, Wang Yuxing communicated with upstream and downstream cooperation units many times based on the highly integrated characteristics of the product, repeatedly revised the scheme, conducted disclosure and docking around many technical parameters such as voltage level and pole number, and continuously optimized the parameters matching the transmission chain and control system of the unit. He volunteered to be responsible for the simulation calculation of electromagnetic and temperature rise. Through the model equivalence, the coupling calculation of electromagnetic and temperature rise was applied to the semi-direct drive permanent magnet wind turbine for the first time, which enhanced the accuracy of the motor temperature rise calculation and greatly reduced the development risk.

Be a person worthy of everyone's trust.

When asked about the experience of the management team, the simple Shanxi man thought for a long time and said word by word: "I don't think there is experience. It is to set an example in everything and be a person worthy of everyone's trust."

In his view, technical teams are very different from other teams. "Under the conditions of execution, creativity is more needed". Only by stimulating the internal drive of team members and letting everyone take the initiative to do things, think of ideas and create, can the level of scientific research team be improved.

More than individuals, he believes in the strength of the team: "I am more of an assistant to help everyone carry out their work, and things are done by comrades together." How to maximize the strength of the team is one of the most concerned things after he became the head of the department.

In the future, Wang Yuxing has many ideas for the motor technology center: innovative work, talent cultivation, and work ideas for "cost engineering" and technical management. He felt that time was tight and not enough.

He advocated that scientific research and technical support work "everything should be done first", and the degree of refinement of technology determines the success of the follow-up work of the product; in the process of product development, it is necessary to sort out the key new indicators and use requirements of the product, and constantly optimize the scheme in the design process, reduce redundant design, and continuously reduce the cost of the product; after the product is delivered, it is also necessary to sum up experience and resume trading at all the time, for subsequent product development.

"In my opinion, the key point is to put things ahead. Before the product is really developed, many technical details must be finalized, and multi-scheme cost comparative analysis must be carried out on the basis of establishing a design cost accounting model. This is also my personal understanding of the group's concept of" calculating and winning in advance ". In the process of project implementation, the target cost will be refined in granularity so that it can be implemented in comparison with procurement and processing procedures, to ensure that the" win-win control "can be truly implemented; After the completion of the project, we will review the experience in time, analyze the reasons for the deviation between the target cost and the actual cost, and revise the design cost accounting model to achieve" real win after the event "," he said. "My personal experience is that the process of refining every link to let the" win-win-win "concept fall to the ground in research and development is actually the process of technology creating value, it is also the process by which our technicians embody their personal values."
