Overview
The FEETECH SCS46 Servo Motor (model SC-4600-C001) is a serial control BUS servo designed for robotics and automation. Operating at 6–7.4V, it delivers up to 40.5kg.cm stall torque at 7.4V with 300° travel and 0.293° position resolution. A coreless motor, steel gear train, ball bearings, and an aluminium case provide robust performance. The half-duplex asynchronous serial protocol (digital packet) supports IDs 0–253 and 38400bps to 1 Mbps communication, with feedback for load, position, speed, input voltage, current, and temperature.
