NEMA 17 Stepper Motor 42BYGH23
The NEMA 17 Stepper Motor 42BYGH23 features a slim 23 mm stack, 1.8° (200 steps/rev) resolution, and a two-phase bipolar winding. Rated at 1 A per phase with 3.8 Ω resistance, it provides a torque of 0.10 Nm and low inductance for responsive control. Key specifications include high insulation (≥ 100 MΩ @ 500 VDC), dielectric strength of 500 VAC for 1 min, an operating temperature rise limited to 80 °C, and ambient use from –20 °C to +50 °C. Shaft diameter is 5 mm round unless otherwise specified.
Features
- Compact and lightweight form factor for tight spaces.
- Accurate 1.8° steps ensure precise motion control.
- Low power consumption, rated at 1A per phase.
- Compatible with a wide range of stepper drivers.
- Reliable performance for light-duty automation.
