FEETECH SM2912-C001 Servo Motor

The SM-2912-C001 is a high-precision 12V 12kg RS485 serial BUS servo equipped with a high-precision all-metal gear train and no mechanical limiter. Housed in a compact frame measuring 40mm × 28mm × 42.3mm and weighing 102g, this servo supports a wide operating voltage range of 9V–24V DC, delivering a stall torque of 12kg.cm at 12V and a maximum speed of 110RPM. It features an advanced 12-bit encoder that yields a 0.088° position resolution, enabling versatile servo control modes including a 0–360° rotation range and multi-turn arbitrary angle adjustment. Utilizing RS485 bus packet communication, it allows up to 254 selectable ID addresses with adjustable baud rates from 34,800 to 1,000,000 bps. Its electrical profile includes a 16kHz PWM frequency, 35mA quiescent current, 200mA no-load current, 0.8A continuous current, and 2500mA stall current, while mechanically tolerating a maximum axial load of 3N and a maximum radial load of 10N within an operating temperature range of -15℃ to 70℃.

Common use cases: Industrial robot arm joints requiring RS485 bus communication and wide 9–24V voltage compatibility, precision automation end-effectors needing 0.088° resolution multi-turn control, collaborative robot (cobot) joints, CNC auxiliary axes, and applications demanding 12kg.cm torque with 12-bit encoder accuracy over RS485 networks.
