FEETECH STS3025BL Servo Motor
FEETECH STS3025BL Servo Motor
The Feetech ST-3025 Series (ST-3025-C001 & ST-3025-C002) consists of high-performance 12V TTL serial bus smart servos designed for industrial equipment, robotics, and precision drive applications. Housed in premium aluminum alloy cases for optimal heat dissipation, both models integrate a brushless motor, a durable metal gearbox, and a 12-bit high-precision magnetic coding sensor. While sharing a 20kg.cm stall torque, they offer tailored performance configurations: the ST-3025-C001 delivers a high speed of 170RPM, while the ST-3025-C002 operates at a balanced 85RPM. Both smart servos feature 0–360° any-angle control, multi-turn continuous operation, one-key midpoint calibration, and acceleration slow-start/slow-stop. They provide real-time multi-parameter feedback (position, speed, voltage, current, temperature, load) for advanced overload and over-current protection.
