Product Description
The SP8108-8 is a compact 48V planetary gear robot joint servo motor designed for robotic arms, quadruped robots, articulated joints, exoskeleton systems, and precision robotic motion applications.
It delivers 7.5 N·m rated torque, 22 N·m stall torque, and 110 RPM rated speed, with a rated power of 336W. The integrated design combines the motor, planetary reduction mechanism, 14-bit encoder, and control electronics into a compact robotic joint drive.
The SP8108-8 supports speed and position control and provides CAN / RS485 communication for integration with compatible robot controllers.
With an overall size of approximately Ø92 × 55 mm and a weight of only 396 g, this model offers a useful balance of compact size, relatively low weight, speed, and output torque for robotic joint applications where installation space is limited.
