Why is it called a robot joint module instead of a robot joint motor? Because it's a module that integrates a harmonic reducer, encoder, servo motor, driver, and controller working together. In traditional robot manufacturing processes, companies often need to purchase these separate components individually, which is quite troublesome and often leads to compatibility issues, wasting both time and resources. A high-performance, integrated power module that combines all these components has become a market necessity.
Application of Harmonic Drive Robot Joint Module
In the field of humanoid robots, robot joint modules endow them with human-like flexibility and movement capabilities, completely transforming traditional robot design.
In robotic arm applications, the high precision and high torque characteristics of these robot joint modules make complex tasks effortless, improving production efficiency and quality.
In the aerospace industry, these robot joint modules not only enhance flight stability but also significantly reduce maintenance costs, ensuring safer flights.
In the medical device industry, integrated robot joint modules enable high-precision control for performing complex surgical procedures.
Features of Harmonic Drive Robot Joint Module
High torque density: Within a volume comparable to an adult joint, it outputs sufficient power to drive a limb.
Low torque fluctuation: This prevents "stuttering" during movement, which is particularly crucial for service robots and surgical robots. Currently, top-tier products have torque fluctuations controlled to within 0.5%.
Strong overload capacity: During sudden movements (such as sudden turns), the motor needs to withstand instantaneous loads 5-10 times its rated value; otherwise, "muscle weakness" may occur.
Extreme environment adaptability: From cold storage at -30℃ to high-temperature workshops, the motor needs to remain stable across a wide temperature range while also being resistant to dust and liquid ingress.

Cobots Robot Arm T type Harmonic Rotary Joint ModuleThe T-type harmonic joint module is a highly integrated robotic joint unit that combines a harmonic reducer, torque motor, precision sensors, brake, and driver. It is called “T-type” because the output flange is perpendicular to the motor shaft, forming a T-shaped layout ideal for rotary robot joints.
Designed for collaborative robots, the module simplifies development by integrating key components into one compact, plug-and-play unit. This greatly shortens the development cycle, lowers costs, and makes building a robotic arm almost as easy as assembling LEGO blocks. Its high integration also improves maintenance efficiency and expands the applicability of robotic-arm technology.
