FEETECH SCS125 Servo Motor

The SCS125 is a high-performance 7.4V 25kg-class TTL serial control BUS servo built with a reliable core motor and a rugged PA+Aluminum composite case for enhanced durability and heat dissipation. Optimized for multi-joint robotics and intelligent control systems, it features ultra-tough steel gears, dual ball bearings, a standard 25T/OD5.9mm horn gear spline, and no mechanical limit angles. Operating within a versatile 4-8.4V voltage range, this digital BUS servo delivers a powerful peak stall torque of 25kg.cm and a rated torque of 8.3kg.cm at 7.4V, achieving a responsive no-load speed of 0.151sec/60°. Utilizing digital packet commands and a half-duplex asynchronous serial communication protocol, it supports an expandable ID range of 0-253 and adjustable communication speeds from 38400bps up to 1 Mbps. It offers a 220° running degree (0~1024 steps) with a fine position sensor resolution of 0.215°/pulse. Weighing 63.5±1g with a 15CM connector wire, it outputs rich telemetry feedback (load, position, speed, input voltage, and temperature), making it an advanced choice for closed-loop robotic linkages.
