ST-3025-C002 High-Torque Brushless Smart Servo With 40 kg.cm Torque, 360deg Control and Magnetic Encoder
The ST-3025-C002 is a high-torque TTL serial-bus smart servo designed for industrial robotics, robotic joints, automation equipment, AGVs, and other demanding motion-control applications. Operating at 12V, it delivers up to 40 kg.cm stall torque with a no-load speed of 0.117 sec/60deg or approximately 85 RPM. Its 12-bit magnetic encoder provides 4096-position resolution across 360deg for accurate closed-loop angular control.
The servo combines an aluminium case, steel gearbox, brushless motor, and ball bearings for reliable operation under repeated mechanical loads. It supports 0-360deg position control, continuous-rotation modes, step operation, and multi-turn positioning. TTL serial-bus communication also provides real-time feedback for position, speed, input voltage, current, temperature, and load, enabling system monitoring and electronic protection functions.
