NEMA 11 Stepper Motor 28BYGH50
The 28BYGH50 is a two-phase bipolar hybrid motor with a 28 × 28 mm flange and a 50 mm stack, delivering 1.8° (200 steps/rev) resolution. It’s wired in a 4‑lead configuration and features a 5 mm D-type shaft. This version is wound for 1 A per phase with 4 Ω resistance, resulting in holding torque of approximately 0.17 Nm. Phase inductance is estimated at 5 mH – 6 mH, with insulation resistance ≥ 100 MΩ @ 500 VDC and dielectric strength 500 VAC for 1 min. It supports continuous operation with temperature rise ≤ 80 °C in ambient –20 °C to +50 °C environments.
Features
- 1.8° (200 steps/rev) step angle with ±5 % accuracy.
- Bipolar, 2‑phase (4‑lead) microstepping-compatible wiring.
- Rated current 1 A per phase.
- Phase resistance 4 Ω.
- Phase inductance 5 mH – 6 mH.
- Holding torque 0.17 Nm.
- 5 mm D-type shaft for secure coupling.
- High insulation ≥ 100 MΩ @ 500 VDC; dielectric strength 500 VAC / 1 min.
- Continuous operation with ≤ 80 °C rise; ambient –20 °C – +50 °C.
