Product Description
The SP8115-36 is a 48V high-torque planetary gear robot joint servo motor designed for robotic joints that require high output torque at controlled low speed.
With 48 N·m rated torque, 190.2 N·m stall torque, and a rated output speed of 28 RPM, this actuator is suitable for compatible robotic arms, legged robots, exoskeleton mechanisms, and articulated robotic systems requiring high-torque joint motion.
The integrated architecture combines the motor, planetary reduction mechanism, 14-bit encoder, and control electronics into a compact robotic joint drive. It supports speed and position control with CAN / RS485 communication for integration into compatible robotic control systems.
The SP8115-36 provides a high-torque actuator option for robotic applications where output torque is prioritized over high rotational speed.
