Product Description
Robot joint module customization, including servo drivers, frameless torque motors, harmonic reducers, feedback encoders, brakes, etc. The core components of the robot joints are connected and integrated into a modular assembly, and designed encapsulated into a 90° corner shape suitable for robot joints, it can be used as a complete joint assembly directly on the robotic arm of an industrial robot.

Advantages of The Robot Joint Module
1.The frameless torque motor has a wide range of types and a wide range of performance characteristics. According to the actual application, the optimal solution is matched to prevent large horse-drawn carts. At the same time, combined with a special harmonic reducer, it can play the best efficiency and ensure high-quality and stable operation;2.The maximum torque reaches the peak performance of the harmonic reducer;
3.Realize the maximum continuous torque output, effectively control the temperature rise of the motor and the temperature rise of the harmonic reducer, and ensure the trial life;
4.Customized module installation shape can be directly connected or parallel connection structure of transmission mechanism such as synchronous belt.





election Method
1.The end of the joint adopts standard mechanical interface and motor interface options;2.Diversified control communication methods, support serial communication, CANopen communication protocol and Ethernet communication based on Ethercat;
3.The feedback control signal is diversified, and the double feedback system can be used, or only the multi-turn absolute encoder feedback, and the mechanical installation method can be customized.
