Product Description
The SP8115-9 is a compact high-torque planetary gear robot joint servo motor designed for robotic arms, exoskeleton joints, quadruped robots, articulated robots, and precision robotic motion systems.
Operating at 48V, it delivers 15.27 N·m rated torque, 54.55 N·m stall torque, and a rated output speed of 120 RPM. The integrated design combines the servo motor, planetary reduction mechanism, 14-bit encoder, and control electronics into a compact joint drive solution.
The SP8115-9 supports speed and position control together with CAN and RS485 communication, allowing integration into compatible robotic control architectures. Integrated temperature monitoring is also specified.
With a compact Ø96 × 48.5 mm body and a weight of approximately 705 g, this actuator is suitable for robotic joints requiring a combination of high torque, moderate output speed, and compact installation.
