Rotary module for robots RJM series

Overview
INFRANOR robot joints are high-precision, lightweight rotary modules with compact, high-torque drives designed for industrial and collaborative robotics. They offer excellent positioning accuracy and repeatability, straightforward installation and integration with a wide range of controllers, and robust mechatronic design for extended operational life.

Key features

• Compact torque drives with up to 6× overload capacity
• High-precision positioning and repeatability
• Vector-control algorithm for high-frequency motion control
• Compatibility with a broad range of common controllers (EtherCAT support)
• Compact, lightweight design for easy integration into industrial or collaborative robot concepts
