About this model
The EBA-17 is the standard planetary gear actuator for NEMA17 motors, also at a 38.4:1 ratio. It's used across the EB-15, EB-65, EB-300, and EB-310 arms — this is the workhorse actuator in the lineup. For the model in STEP file Efficiency Output Torque 70% (conservative) 13.44 Nm 80% (typical) 15.36 Nm 85% (optimistic) 16.32 Nm Typically 70–85% for 3D-printed planetary gears due to friction — real-world loss, not just a formality. Efficiency Force at 200mm* 70% 67.2 N 80% 76.8 N 85% 81.6 N So realistically, expect somewhere around 67–82 N of force at 200mm from the joint, with ~77 N as a reasonable middle estimate. That's roughly 7–8 kg-force equivalent at that point. A couple of caveats worth keeping in mind: this is the actuator's torque capability, not necessarily what the arm can safel…
