36Kr learned that Beijing Hangyu Servo Technology Co., Ltd. (hereinafter referred to as "Hangyu Servo"), a manufacturer and R & D company of servo systems, recently announced the completion of tens of millions of yuan in Series A+ financing. This round of financing was led by Lushi Investment, followed by Junyuan Capital, and the old shareholder Xiyang Capital also participated in additional investment. The funds raised will be used for team expansion, venue and equipment upgrade, and cash - flow replenishment.
Hangyu Servo was established in 2021 and focuses on the R & D, production, sales, and service of high - precision servo systems in the aerospace, aviation, and navigation fields. It is now a specialized and sophisticated enterprise in Beijing. The founder, Zheng Huayi, graduated from Beihang University for both his undergraduate and postgraduate studies. After graduation, he worked in a research institute of the China Academy of Launch Vehicle Technology for nearly 20 years and once served as the chief designer of the servo system of the Long March 5 launch vehicle and held leadership positions in several important departments.
The core R & D team of Hangyu Servo comes from the "Seven National Defense - related Universities" and relevant scientific research institutions. They have the R & D, production, manufacturing, and testing capabilities for three major types of servo mechanisms: valve - controlled hydraulic, high - power electromechanical, and electro - hydrostatic. They also have the design and development capabilities for servo software and hardware, comprehensively covering from systems, single machines, components to underlying components, from measurement, communication, control to drive circuits, and from motors, mechanical and fluid transmissions, actuators to control algorithms.
Zheng Huayi introduced that currently, the aerospace field is the company's core business. Its customers cover the R & D units of mainstream commercial rockets, hypersonic vehicles, target missiles, and satellites. The aviation field is regarded as the company's second growth curve, and its customers cover the R & D units of large fixed - wing UAVs with a payload of more than one ton, tilt - rotor UAVs, electric vertical take - off and landing vehicles (eVTOL), and target drones. Navigation is a newly developed direction for the company, mainly providing servo systems, electric propulsion technologies, and services for scientific research and special navigation vehicles. Currently, Hangyu Servo has delivered hundreds of sets of servo mechanisms (steering gears) and supporting controllers and has obtained relevant industry qualifications.
Aerospace servo products
Self - developed valve - controlled hydraulic, high - power electromechanical, and electro - hydrostatic servo systems, providing complete solutions for multiple scenarios
The core task of the servo system is to enable machines to complete various actions accurately, quickly, and stably. It is now widely used in scenarios such as rockets, defense equipment, aircraft, ships, special vehicles, and special robots.
The electromechanical servo system was first applied in relatively light - load scenarios in the industrial field with low dynamic response requirements, such as robot joints. In the early years, limited by the power density, volume, weight, and response speed of motors, rockets and aircraft used valve - controlled hydraulic servo systems.
Around 2000, with the development of rare - earth permanent - magnet materials, the power density of motors increased. Coupled with the breakthroughs in control chips and software algorithms, it became possible to apply electromechanical servo systems in the aerospace field. Since 2010, electromechanical servo systems have been widely used in rockets and aircraft. Around 2015, SpaceX achieved the first on - land rocket recovery, which verified the concept of reusable rockets, and the domestic commercial aerospace field entered a period of rapid development. Meanwhile, with the development of the low - altitude economy, the technology diffusion of domestic large aircraft, and the rise of eVTOL, the domestic private aviation industry also achieved great development. The demand for reliability in the aerospace field is getting higher and higher, and redundant designs for servo systems have gradually emerged. Starting from the first - generation valve - controlled hydraulic servo redundancy technology, through the iteration and upgrade of the second - generation electromechanical servo redundancy, it finally developed into the third - generation electro - hydrostatic redundancy technology.
Electro - hydrostatic servo is a technology that combines electromechanical servo and hydraulic servo. Its control is still completed by the motor, but it uses a hydraulic actuator, combining the control accuracy of electromechanical servo and the high - load capacity of hydraulic servo, achieving a double leap in performance and reliability. At the same time, it avoids the problems of easy leakage and frequent maintenance in traditional hydraulic servo and the difficulty of redundant design in electromechanical servo.
In terms of technological advancement, electro - hydrostatic servo is currently the most ideal solution for servo systems. However, due to the scarcity of technology and high cost, its application scenarios are still limited to high - end industrial and military aerospace fields, such as the US F35 fighter jet, the C929 large aircraft of COMAC, and the new - generation launch vehicles. Currently, only a few companies in the world have mastered this technology and achieved mass production, including traditional hydraulic and servo giants such as Parker Hannifin and Moog in the United States. In China, only a few aerospace and aviation professional research institutions have applied such products, and Hangyu Servo is one of them.
In terms of product variety, Hangyu Servo's products cover all current mainstream servo technologies, including valve - controlled hydraulic servo, high - power electromechanical servo, and electro - hydrostatic servo.
In Zheng Huayi's view, the product performance of Hangyu Servo has reached the first - tier level in the industry. "In terms of product reliability, even without redundant design, our products can still ensure extremely high reliability. If customers have higher requirements, we can provide a complete set of redundant solutions with independent intellectual property rights, including two technical routes: pure - electric redundancy and electro - hydrostatic redundancy. In terms of product durability, our servo system products have excellent service life performance. They fully support rockets to be reused dozens of times and aircraft to fly thousands of hours. Of course, this is based on the premise that they are used within the designed load."
In 2024, the order revenue was tens of millions of yuan, and hundreds of sets of servo mechanisms (steering gears) and supporting controllers have been delivered
The aerospace segment contributes the most order revenue to Hangyu Servo. The company mainly provides high - precision servo systems and steering - gear system supporting solutions for commercial rockets, hypersonic vehicles, satellites, target drones, etc. The product power covers the full range from 2kW to 40kW, which are used for the swing control of solid/liquid engine nozzles of rockets, the control of aircraft control surfaces, and the thrust - adjustment control of engines.
Currently, Hangyu Servo has delivered hundreds of sets of servo mechanisms (steering gears) and supporting controllers to customers in the aerospace field. The main customers include leading enterprises such as Dongfang Space, Zhongke Aerospace, Jianyuan Technology, and Lingkong Tianxing. Among them, the 40kW servo system independently developed by Hangyu Servo helped a certain type of large - thrust solid - strap - on rocket fly successfully, breaking the maximum - power application record of servo systems for solid rockets both internationally and domestically.
As the construction of low - orbit satellite constellations accelerates and the number of rocket launches increases significantly, Zheng Huayi believes that with its leading market share, technological advantages, and supporting experience in the current aerospace servo field, Hangyu Servo is expected to capture more than half of the market share in the future.
In the aviation field, the company mainly provides steering - gear products for large fixed - wing UAVs with a payload of more than one ton, tilt - rotor UAVs, eVTOLs, etc., including control - surface control, throttle and pitch control, door and landing - gear retraction, steering, and braking control. More than ten UAV enterprises such as Tongfei and Yitong are its customers.
Navigation is a new strategic business developed by the company this year. It mainly provides servo systems, electric - propulsion technologies, and services for scientific research and special navigation vehicles. Currently, it has provided several prototype products for trial use and signed multiple strategic cooperation intentions.
When talking about market competition, Zheng Huayi said, "In terms of technology and quality, Hangyu Servo strives to catch up with in - system scientific research institutions; in terms of price and service, it strives to be more characteristic of a commercial company. At the same time, we will also be a reserve force and a useful supplement to the national - team players."
From June 2024 to the present, Hangyu Servo has completed three rounds of financing. In 2024, the order revenue was tens of millions of yuan, and the company achieved profitability. Currently, the Series B financing of Hangyu Servo is being planned and promoted.
