The joint motor module of humanoid robots is a core component driving robotic movements. It mostly integrates motors, reducers, encoders, sensors and other components, and is divided into rotary and linear types to adapt to the motion requirements of different joints. Installed on the neck, shoulders, hips, knees and other body parts, with micro versions applied in dexterous hands, it directly determines the motion precision and flexibility of humanoid robots.

Frameless torque motors are the mainstream choice for high torque density, while micro coreless motors are adapted for dexterous hands. Combined with harmonic or planetary reducers, it enables low-backlash transmission; encoders achieve micron-level positioning accuracy, and torque sensors realize flexible control by real-time force feedback.

Joint modules are designed with differentiation for specific applications: lower limb modules focus on high load capacity and impact resistance, while hand modules pursue compactness and precise response. The integrated design not only reduces the overall volume, but also ensures the accurate execution of complex movements through high-speed communication.
