From April 24 to 26, 2025, Halls 7 and 8 of the Shenzhen Futian Convention and Exhibition Center hosted the Fair Plus 2025 – Robotics Full Industry Chain Expo. This annual event brought together key players across the entire robotics value chain, from control systems and sensors to joint modules and gear reducers, with a sharp focus on upstream-downstream collaboration and breakthroughs in core components.
Among the global exhibitors was Kollmorgen, a century-old brand renowned for its motion control expertise. The company showcased its high-power density compact servo motor series, drawing significant attention from attendees. At the event, China Exportsemi Editor-in-Chief Chen Lu interviewed Chen Kaiyuan, Industry Sales Manager at Kollmorgen, for an in-depth discussion on the company’s strategic priorities in the robotics sector, key product features, and market localization strategies in China.

A Century of Innovation, Deep Roots in the Asia-Pacific Market
“Kollmorgen is a motion control and automation components provider with a legacy of over 100 years,” explained Chen Kaiyuan. “In the Asia-Pacific region, our business covers mainland China, Southeast Asia, Taiwan, and parts of Korea. We operate a registered company and manufacturing facility in Tianjin, with nearly 200 employees—over 50 of whom are dedicated sales professionals.”
Renowned for its robust, industrial-grade solutions, Kollmorgen has been a trusted name in automation for decades. As the robotics industry accelerates—especially with the commercialization of collaborative and humanoid robots—the demand for compact yet high-performance drive systems is rapidly increasing. To meet these evolving needs, Kollmorgen is continuously accelerating product iteration and local adaptation, expanding its core strengths into robotics applications.
Powering Humanoid Robots: Compact Joints with Mighty Output
At Fair Plus 2025, Kollmorgen exhibited a range of servo motors applicable to industrial, collaborative, and humanoid robots. One standout model featured a compact footprint with high torque output, delivering up to 30 Nm of torque and speeds of 3,000 rpm—all within a fist-sized enclosure. The motor was aptly described as a “mighty performer in a mini package.”
“This product excels in combining high torque and compact size,” said Chen Kaiyuan. “It’s particularly suited for robotic joints, where space is tight and payload demands are high. In a small joint, traditional motors may simply be too bulky, whereas ours can perform powerful motions within limited dimensions.”
When used in humanoid robots, this motor is ideal for high-demand areas like legs, shoulders, and elbows, where requirements for lightweight design, fast response, and high dynamic torque must be carefully balanced—something this motor is engineered to achieve.

Industry Perspective: What Does 30 Nm Really Mean?
So how powerful is 30 Nm in real terms? Industry insiders note that it represents a high-performance threshold. In collaborative robots, joint motor torque typically ranges from 5 to 15 Nm; for industrial robots, 20 to 60 Nm is more common—but often at the cost of larger size and higher energy consumption.
“If this motor can consistently deliver 30 Nm at 3,000 rpm, its power density and thermal performance must be exceptional,” remarked one systems engineer from a robot manufacturer. “As the industry moves toward more integrated and compact joint designs, Kollmorgen’s solution is extremely compelling for companies like ours.”
No Controllers, also a Systems-Level Partner
Interestingly, Kollmorgen does not currently produce robot-specific controllers. However, this hasn’t stopped the company from providing system-level drive solutions.
“We collaborate with customers to recommend compatible controller brands,” explained Chen. “Together with our partners, we can deliver a complete, integrated solution.”
This open and flexible approach allows Kollmorgen to focus on perfecting its core technologies in drive systems, while leaving control strategy implementation to OEMs and system integrators. The result is a more streamlined product line and better resource allocation.
High Power Density Opens the Door to Emerging Markets
As the humanoid robot sector gains momentum, the pursuit of “human-level mobility” is pushing performance demands on drive systems to new heights. “High torque, compact size, and fast responsiveness” are becoming the industry’s top priorities.
“Our focus extends beyond traditional industrial robots—we’re also actively working with innovative robotics companies in fields like humanoid robotics, medical devices, and rehabilitation,” said Chen. Compared to conventional industrial motor buyers, these emerging clients prioritize customization, lightweight design, and intelligent features—all areas where Kollmorgen leverages its century-long expertise and local engineering capabilities.
Conclusion: Making Robotic “Muscles” Smarter and Stronger
At the Fair Plus 2025 show, what stood out wasn’t just the technology inside the motors, but the strategic vision behind them—a commitment to collaboration and integration across the robotics ecosystem. Kollmorgen’s compact 30 Nm servo motor isn’t just a piece of hardware; it’s a muscle engine poised to power the agile movements of next-generation humanoid robots.
As intelligent manufacturing and robotics continue to converge, Kollmorgen’s high power density drive solutions are well-positioned to bring greater strength, precision, and flexibility to robotic joints—fueling smarter, more dynamic machines of the future.
