NEMA 16 Stepper Motor 39BYGH40

Description

NEMA 16 Stepper Motor 39BYGH40 The 39BYGH40 is a two-phase hybrid stepper motor in the NEMA 16 frame (39 × 39 mm flange), featuring a compact 40 mm body and 1.8° (200 steps per revolution) resolution. It is available in bipolar configuration with rated current 0.3 A – 0.4 A per phase, phase resistance 30 Ω – 40 Ω, and holding torque between 0.11 Nm – 0.21 Nm. Phase inductance ranges from 20 mH – 45 mH, and rotor inertia spans 20 g·cm² – 32 g·cm², depending on the specific model. The motor uses a 5 mm round shaft, offers insulation resistance of ≥ 100 MΩ at 500 VDC, dielectric strength of 500 VAC for 1 min, temperature rise up to 80 °C, and supports ambient operation from –20 °C to +50 °C. Features 1.8° (200 steps/rev) step angle with ±5 % accuracy. Bipolar, 2‑phase wiring suitable for standard stepper drivers. Rated current 0.3 A – 0.4 A per phase. Phase resistance 30 Ω – 40 Ω. Holding torque 0.11 Nm – 0.21 Nm. Phase inductance 20 mH – 45 mH. Rotor inertia 20 g·cm² – 32 g·cm². 5 mm shaft for compact coupling. High insulation (>100 MΩ @ 500 VDC) and dielectric strength (500 VAC / 1 min). Capable of continuous operation with ≤ 80 °C rise; ambient range –20 °C to +50 °C.
