Highly Integrated Design


The actuator integrates the drive, dual hollow encoders, frameless motor, harmonic reducer, and sensors into a single unit. By combining power, transmission, feedback, and control functions, it reduces external connections and simplifies robot joint design and installation.





High Torque Density in a Compact Design


The compact integration of the frameless motor and harmonic reducer provides high output torque within limited installation space. The actuator balances lightweight design and power performance for robotic systems with strict size and weight requirements.






High-Precision Dual Hollow Encoders


The dual hollow encoder design provides joint position feedback and motion-state detection, supporting precise motion control and responsive joint operation. The hollow structure also provides additional space for cable routing and mechanical integration.






High-Precision Torque Control


With high-precision torque control and reliable load inertia identification, the actuator enables refined control of joint output conditions, helping improve motion stability and dynamic response in robotic applications such as collaborative and humanoid robots.
