Product Description
The RI50-70 is a compact hollow shaft harmonic drive robot joint actuator designed for robotic arms, articulated robots, humanoid robotics, and compact motion-control systems.
It integrates a brushless motor, harmonic drive reducer, encoder feedback, and hollow-shaft structure into a compact joint module, reducing the complexity of separately integrating the motor, gearbox, and feedback components.
The hollow-shaft architecture provides internal space for cable and wiring routing through the joint, helping simplify mechanical integration in compact robotic arms and articulated mechanisms.
The RI50-70 is available with CAN or EtherCAT communication, single or dual encoder feedback, and optional brake configurations for different robotic control requirements.
