FEETECH STS3045 Servo Motor

The ST-3045-C001 is a compact 6V 6kg all-metal 360-degree magnetic encoder single-shaft serial BUS servo integrated into a robust aluminum case. Equipped with a high-efficiency coreless motor, precision metal gears, and durable ball bearings, this servo features a 25T/OD5.9mm horn gear spline and plastic/POM horn configurations with no mechanical limits. Measuring 36mm × 15mm × 29.2mm and weighing 34.8±1g, it operates across a wide 4.8–7.4V voltage range, delivering a peak stall torque of 6kg.cm, a rated torque of 2kg.cm, a no-load speed of 0.133sec/60°, and a stall current of 1.4A at 6V. Driven by digital packets, it implements half-duplex asynchronous serial communication (38400bps–1Mbps, ID range 0–253) to achieve continuous 360° rotation with 0–4096 resolution steps. For precise closed-loop control, it offers comprehensive real-time telemetry feedback continuously monitoring load, position, speed, input voltage, and temperature.

Common use cases: Small humanoid robot finger, wrist and ankle joints requiring 360° magnetic encoder feedback, compact educational robot platforms with serial BUS daisy-chain wiring, lightweight RC models needing serial BUS control, and applications requiring 6kg.cm torque in a sub-35g package with full telemetry.
