Description

The DAMIAO DM-JH11-2EC is a compact harmonic-drive robotic joint module designed for robotic arms, humanoid robots, quadruped robots, exoskeleton systems, and precision automation equipment. Integrating a harmonic reducer, brushless servo motor, and dual inductive encoder feedback system into a single compact actuator, the DM-JH11 delivers high positioning accuracy, low backlash, excellent repeatability, and smooth motion control.

Available in 51:1 and 101:1 reduction ratios, the DM-JH11 series provides different speed and torque characteristics to suit shoulder joints, elbow joints, wrist joints, lightweight industrial robots, and research robotics platforms. The built-in dual inductive encoder architecture enables high-resolution feedback for accurate position and motion control while supporting CAN and CAN FD communication.

Designed for developers seeking a high-performance yet cost-effective robotic actuator, the DM-JH11 combines compact dimensions, integrated construction, and reliable harmonic transmission technology into a professional-grade robotic joint solution.
