Topband Motor Showcases Micro-Actuator Innovations for Humanoid Robots

On June 24, 2026, the "2026 (3rd) China Intelligent Manufacturing Future Humanoid Robot Industry Development Conference and Humanoid Robot Drive Motor and Key Materials Development Forum" was held in Hangzhou, Zhejiang Province. Hosted by ZRT (Zhourui Trading Network) and co-organized by Unitree Robotics, the conference brought together hundreds of representatives from domestic industrial enterprises, industry associations, and research institutions. Shenzhen Topband Motor Co., Ltd., as a supporting unit of the conference, was invited to attend. The company's Marketing Director delivered a report entitled "Ultimate Space, High-Efficiency Output – The Revolution of Micro-Actuation Systems," which attracted widespread attention from the attendees.

This conference focused on humanoid robot drive systems and key material technologies, with a particular emphasis on the technological applications and market development of frameless torque motors and coreless motors in the humanoid robot field. In his report, Topband Motor's Marketing Director elaborated on the technical path and industrialization practices of achieving high-efficiency output of micro-actuators under extreme space constraints.

The core product, the "Lingqu Precision Transmission Micro-Engine System," has attracted significant attention. The report highlights Topband Motor's independently developed "Lingqu Precision Transmission Micro-Engine System." This system integrates core components such as a hollow cup motor, gearbox, lead screw, and encoder, boasting significant advantages such as high energy density and space-saving installation. It perfectly meets the dual requirements of dexterous hands for both "small size" and "high output." Approximately 15 units can be installed within a single dexterous hand, providing a revolutionary solution for the precision drive of humanoid robot dexterous hands.

Technological Breakthroughs and Industrialization Progress Topband Motor has cultivated expertise in the micro-motor field for many years and is one of the earliest domestic companies to achieve mass production of hollow cup motors, breaking the technological monopoly of Europe, America, and Japan, and ranking among the top domestic manufacturers. The company's micro-drive actuator modules can be made in diameters of 6-40mm, perfectly fitting into the hand area of robot dexterous hands; motor power density is increased by over 20%, efficiency by over 15%, and gearbox transmission efficiency reaches over 90%.
In terms of industrialization, Topband Motors has initially reached mass production order intentions with several leading domestic customers, and expects to achieve mass production and delivery of coreless motors and the Lingqu Precision Transmission Micro-Engine System for robot dexterity hands by 2026. Currently, the Lingqu Precision Transmission Micro-Engine System has already secured small-batch orders, laying a solid foundation for large-scale mass production.
