Robot Joint Module

This model Robot Joint Modules is the best choice for Robot Arm manufacturer with much lower cost, modular design and compact structure, which save customers hundreds of mechanical and electronic components selection, design, procurement, assembly labor and time costs.

Features of Robot Joint Module

Quick build robot
Save the manpower and time cost of selecting, designing, purchasing and assembling hundreds of mechanical and electronic devices

Small and precise
The outer diameter is only 70mm, the OD of middle hole of which lines can pass through is 18mm.
0.98kg ultra-lightweight, reduce joint weight, effectively ensure a reasonable weight ratio of the robot.

Support multiple communication protocols
With EtherCAT, CANopen communication, open position loop, speed loop, current loop data and PID real-time adjustment, suitable for dynamic load and variable inertia robot applications.

Built-in dual absolute value encoder
19-bit absolute encoder at the output, repeat positioning accuracy up to ±10 arc seconds, absolute positioning accuracy up to ±45 arc seconds.

Robot Joint Module Application

The robot joint modules are widely used in robotics, industrial automation, medical equipment and other fields.
