Harmonic Drive Gearbox X17-34-30A Ratio 1:30 with NEMA 17 Stepper Motor

Description

The X17-34-30A combines a standard NEMA 17 hybrid stepper motor with a 30:1 harmonic‑drive gearbox into a remarkably compact 60 mm‑long assembly. Retaining the familiar 42 × 42 mm flange and 34 mm stack, it delivers 2.2 N·m of continuous torque at just 1.4 A per phase. Unlike typical planetary gearmotors, its flex‑spline design achieves less than 2 arc‑min of backlash, providing ultra‑smooth, near‑perfect positional accuracy. This intrinsic precision eliminates mechanical “dead zones” and ensures repeatable motion under bidirectional loads.
