FEETECH STS3009 Servo Motor
FEETECH STS3009 Servo Motor
The ST-3009-C001 is a 7.4V 11.5KG magnetic encoder double shaft TTL servo designed with an aluminium case, metal gears, ball bearings, and a brushless motor. It features a 25T/OD5.9mm horn gear spline and a 0° rocker phantom with no mechanical limit. With physical dimensions of 20mm x 30mm x 36.5mm and a weight of 45±1g, it operates within a 4.8-8.4V voltage range. At 7.4V, it delivers a peak stall torque of 11.5kg.cm, a rated torque of 3.8kg.cm, a no-load speed of 0.1sec/60° (100RPM), and a stall current of 2.8A. Utilizing digital packets for command signals, the servo communicates via half duplex asynchronous serial communication across an ID range of 0-253, featuring a factory default speed of 1Mbps (adjustable from 38400bps to 1Mbps). It supports a continuous 360° running degree (0~4096 steps) and provides real-time telemetry feedback for load, position, speed, input voltage, current, and temperature.
