en.Wedoany.com Reported - Welling Robot Components, under the Industrial Technology Division of China's Midea Group, showcased its fully self-developed integrated power module for humanoid robots at the 2026 6th Global xEV Drive System Technology and Industry Conference. Wang Zhen, a motor technology expert at Welling Robot Components, delivered a speech titled "Technology and Industrial Practice of Integrated Power Modules," noting that humanoid robots are transitioning from laboratories to engineering applications, and integrated joint modules will lay the foundation for commercialization.
As the core actuation component of robots, the performance of joint modules directly determines the overall flexibility, load capacity, and endurance of the machine. Current traditional split solutions—integrating externally purchased motors, reducers, and drives—suffer from issues such as large size and weight, low integration, complex wiring leading to poor reliability, delayed dynamic response, and high assembly and debugging costs, making them difficult to support mass production of humanoid robots.
Leveraging Welling's over 40 years of technical expertise in the motor field, along with Midea Industrial Technology's R&D and manufacturing foundation, Welling Robot Components has launched fully self-developed harmonic and planetary "integrated power modules" covering all-scenario joint requirements, achieving deep synergy among control, drive, and transmission in a three-in-one system.
Welling's harmonic joint module is positioned for light-load, high-sensitivity applications, offering advantages such as extreme lightweight design, micron-level precision, and silent, low-noise operation. It deeply integrates the motor, harmonic reducer, and encoder to maximize torque density within a compact space, making it suitable for non-load-bearing joints like wrists, elbows, and necks, and serving as an ideal power unit for medical and collaborative robots. Welling's planetary joint module targets heavy-load scenarios, featuring exceptional impact resistance, high structural rigidity, and long-life redundancy. It employs a high-performance planetary gear transmission scheme to maintain output stability under extreme conditions, making it suitable for load-bearing joints such as hips, knees, and ankles, providing sustained power for robot walking, load-bearing, and material handling.
With full-stack self-development of core components such as harmonic reducers, frameless torque motors, and servo drives, Welling Robot Components has achieved a qualitative leap from "component assembly" to "system synergy," excelling in lightweight design, millisecond-level response, and full-lifecycle reliability, earning widespread acclaim from industry customers. Wang Zhen stated that under the same specifications, the integrated solution achieves a qualitative leap in overall efficiency compared to competitor products, truly realizing a system integration capability of "1+1+1 > 3."
Welling Robot Components stated that it will break down technical barriers, establish transparent and trust-based cooperation mechanisms, share R&D achievements and market opportunities with partners, and leverage a highly reliable guarantee system covering R&D, manufacturing, testing, and delivery to strengthen the foundation of China's robot industry supply chain, providing global customers with comprehensive support from selection to mass production, and driving the expansion of "robot+" application scenarios.
