About this model

SA1755 is a stronger version of my SA1737 compact rotary actuator built around a NEMA 17 stepper motor with 9:1 reduction ratio, designed for hobby robotics, custom mechanisms and mechatronic projects. It offers high output torque, low backlash and continuous rotation capability in a compact and integration-friendly form factor. The actuator is designed to work with standard external stepper drivers such as TMC2208 or TMC2209 and can be equipped with the AA360 absolute magnetic encoder module for position feedback and closed-loop correction. This makes it suitable for robotic joints, pan-tilt systems, experimental arms, custom automation mechanisms and other motion-control applications where compact size and repeatable positioning matter. --- Main features: NEMA 17 based design 9:1 gearbox…
