FEETECH STS5420 Servo Motor
FEETECH STS5420 Servo Motor
The ST-5420-C001 is a high-performance 7.4V 25KG coreless steel gear 360 single shaft servo housed in a durable aluminium case. Driven by a coreless motor with a steel gear train and ball bearings, it features a 25T/OD5.9mm horn gear spline and a 0° rocker phantom with no mechanical limit. Its physical dimensions are 40.6mm x 20mm x 30mm, with a weight of 65.5±1g. Operating over a 4.8-8.4V voltage range, it delivers a peak stall torque of 25kg.cm, a rated torque of 8.3kg.cm, a no-load speed of 0.111sec/60° (90RPM), and a stall current of 4.7A at 7.4V. Utilizing digital packets for command signals, the servo communicates via half duplex asynchronous serial communication across an ID range of 0-253 with speeds from 38400bps to 1Mbps, providing a full 360° running degree (0~4096 steps). For advanced closed-loop systems, it outputs comprehensive real-time telemetry feedback covering load, position, speed, input voltage, current, and temperature.
