ST-3025-C001 High-Speed Brushless Smart Servo with 20 kgcm Torque, 170 RPM speed, and a 12-bit magnetic encoder
The ST-3025-C001 is a high-speed TTL serial-bus smart servo designed for industrial equipment, robotics, automated mechanisms, and motion-control applications requiring fast and precise rotary positioning. Operating at 12V, it delivers up to 20 kgcm stall torque with a no-load speed of 0.059 sec/60deg or 170 RPM. Its 12-bit magnetic encoder provides 4096-position resolution across 360deg for accurate closed-loop angular control.
The servo combines a full aluminium-alloy case, steel gearbox, brushless motor, and ball bearings for reliable mechanical performance during repeated operation. It supports 0-360deg position control, continuous multi-turn rotation, and step operating modes. Configurable acceleration enables smooth start and stop movement, while feedback for position, speed, voltage, current, temperature, and load allows real-time monitoring and supports overload and over-current protection.
