NEMA 14 Stepper Motor 14HS10‑0803S‑EGS5 with 5:1 EG Series Planetary Gearbox

From the shop's description

NEMA 14 Stepper Motor 14HS10‑0803S‑EGS5 with 5:1 EG Series Planetary Gearbox The 14HS10‑0803S‑EGS5 is a two‑phase bipolar hybrid motor with a 35 × 35 mm flange and 26 mm stack, offering 1.8° (200 steps/rev) resolution. It’s wound for 0.8 A per phase with 2.8 Ω (±10 %) phase resistance, delivering holding torque of 0.25 Nm–0.30 Nm. Phase inductance ranges 4 mH–6 mH (±20 %). The motor uses a 8mm keyway shaft and integrates a 5.18:1 EG‑series planetary gearbox for low‑backlash precision. It supports insulation resistance ≥ 100 MΩ @ 500 VDC, dielectric strength 500 VAC for 1 min, and continuous operation with ≤ 80 °C temperature rise in an ambient range of –20 °C to +50 °C. Features 1.8° (200 steps/rev) step angle with ±5 % accuracy. Bipolar, two‑phase (4‑lead) microstepping‑compatible wiring. Rated current 0.8 A per phase. Phase resistance 2.8 Ω (±10 %). Phase inductance 4 mH – 6 mH (±20 %). Holding torque 0.25 Nm – 0.30 Nm. 8 mm keyway shaft for secure mechanical coupling. Integrated EGS5 planetary gearbox (5:1) for low‑backlash precision. High insulation and dielectric performance ensures reliability. Continuous operation with ≤ 80 °C rise; ambient –20 °C – +50 °C.
