At the Fair of AI and Robotic, plus conference held from April 24 to 26 at the Shenzhen Futian Convention and Exhibition Center, Mr. Huang Kun, Sales Director of Suzhou JOYO Electric Technology Co., Ltd., sat down with Chen Lu, Editor-in-Chief of China Exportsemi, for an in-depth interview. Huang shared insights into JOYO’s development journey, core technological strengths, product portfolio, downstream applications, and ambitions for domestic substitution. Originating in the military sector, evolving through the medical field, and now rapidly growing in the robotics domain, JOYO is emerging as a key player driving the industrialization of humanoid robots with its high-performance, high-integration micro servo systems.

1. From Military Origins to Medical Innovation and Robotic Expansion
Founded with a focus on military applications, JOYO Electric transitioned into the medical equipment sector, leveraging its expertise in high-reliability and precision control technologies. In recent years, amid the rapid rise of the robotics industry, the company has strategically migrated its core technologies into emerging scenarios such as humanoid and surgical robots. Guided by the philosophy of being “reliable, robust, and durable,” JOYO has developed a lineup of high-performance, miniaturized, and fully integrated servo power systems. These include frameless motors, joint modules, integrated actuators, and micro drives.
“All of our products are independently developed and manufactured in-house. Key components—gears, motors, drives, encoders—are all produced by us, ensuring complete technological control at every stage,” said Huang Kun. “We don’t just make motors—we deliver highly integrated actuation systems. That’s the key to breaking foreign monopolies in core robotic components.”
2. A Robust Product Portfolio: From Frameless Motors to Integrated Servo Modules
During the interview, Huang highlighted JOYO’s flagship products: the 14mm mini frameless motor and the 16mm micro drive. These ultra-compact and highly integrated products are ideal for end-joint systems with tight space constraints and high-power density requirements. They are widely used in dexterous hands, finger joints of humanoid robots, and the end-effectors of surgical robots.
Unlike traditional coreless motors, JOYO’s frameless motors adopt permanent magnet synchronous motor (PMSM) technology, offering higher power density and better thermal efficiency within the same size. “Our motors are not only compact and lightweight but also excel in thermal control. Under equivalent output, the temperature rise is about 20K lower than mainstream industry products—an advantage that’s crucial in precision applications,” Huang noted.
Beyond micro-scale products, JOYO also provides planetary joint modules that integrate reduction gearboxes, motors, drives, and encoders into a single unit. These are well-suited for quadruped inspection robots, special-purpose robots, and other applications demanding high torque density. Fully developed in-house, these modules are already in mass deployment among several clients.
“Our integrated actuators embody our core technical strengths. For example, one of our products weighs just 1.8kg but delivers a force output of up to 8kN—achieving a force-to-weight ratio of 4kN/kg, a benchmark few domestic players can match,” Huang said proudly.

3. MCU + FPGA Dual Architecture: A “Shortcut” in Drive Technology
In terms of servo drives, JOYO employs a unique “MCU + FPGA dual architecture,” combining the flexibility of microcontrollers with the real-time performance of FPGAs. This dual approach effectively addresses the limitations of traditional single-chip architectures in multi-axis robotic control.
“Robotic control requires concurrent data communication and real-time response to even the slightest joint movements. Our dual-architecture system is perfectly suited for these complex demands,” Huang explained. This architecture is giving JOYO a performance edge in competing with high-end drive manufacturers from Europe, the US, and Japan.
4. 300,000 Motors per Year: Strengthening the Foundation for Domestic Substitution
According to Huang, JOYO targets an output of 300,000 frameless motors and 20,000–30,000 key modules in 2025, aiming for an annual revenue of RMB 110 million. The company has already established strategic partnerships with major players in the domestic robotics space, including the Zhejiang Humanoid Robot Innovation Center (led by Professor Xiong Wen) and Suzhou-based Xinghaitu, a Tsinghua-affiliated startup. JOYO is playing a critical supporting role across the humanoid robotics value chain.
Additionally, JOYO’s products have penetrated multiple niche markets including industrial automation, semiconductor equipment, and specialty motors, with several offerings successfully replacing Korean and German servo systems. Customers are increasingly recognizing JOYO’s reliability, compact design, and customization capabilities.
“We’ve always followed a ‘multi-variety, small-batch, high-customization’ path, striving to contribute meaningfully to the domestic autonomy of core components in Chinese robotics,” Huang stated.
5. From Technical Depth to Industry Breadth: Supporting China’s Robotics to “Go Global”
As a hard-tech-oriented national-level “Little Giant” enterprise, JOYO is building a complete solution loop—from micro power systems to full joint modules. Its highly integrated product ecosystem not only enhances the design flexibility of robots but also significantly reduces system integration complexity and cost for clients.
Notably, Huang frequently mentioned the goal of “domestic substitution” throughout the interview. He emphasized that JOYO’s strength in micro servo systems holds inherent strategic value in the age of AI plus robotics—a national priority. The company’s solutions are not only designed for the domestic ecosystem but are also well-suited for global deployment in sectors such as medical, industrial, and defense applications.
“We’re not just competing with traditional component suppliers,” Huang said. “We're leveraging our system integration capabilities to tackle the toughest challenge in robotics—joints—and we aim to be the team that conquers it.”
Conclusion
As China’s robotics industry approaches a breakthrough moment, key component suppliers like JOYO are stepping into the spotlight and climbing the value chain. With the mindset of engineers deconstructing complexity, and the vision of manufacturers rebuilding the supply chain, they are offering truly implementable “Chinese solutions” to the robotics world.
2025 could mark the beginning of the humanoid robot era—and from “frameless motors” to “empowered capabilities,” JOYO’s rise is delivering a small yet mighty force for this transformative age.
