NEMA 34 Stepper Motor 86BYGH127
The 86BYGH127 is a two-phase bipolar hybrid stepper motor featuring a 1.8° (200 steps/rev) step angle and a 127 mm motor length. It is rated for 6 A per phase, with phase resistance around 0.8 Ω, and a phase inductance in the 5 mH – 6 mH range. The motor delivers approximate holding torque of 7.6 Nm – 9 Nm, offering strong performance for high-inertia loads. It features standard 4‑lead bipolar wiring, meets insulation resistance ≥ 100 MΩ @ 500 VDC, and tolerates a dielectric strength of 500 VAC for 1 min. With a temperature rise capped at 80 °C and an ambient operating range of –20 °C to +50 °C, it’s reliable for continuous, rigorous use. Shaft diameter: 14 mm with 5 mm keyway.
