Nema 23 Stepper Motor 57BYGH56
The Nema 23 Stepper Motor 57BYGH56 is a two-phase hybrid motor featuring a 56 mm stack, 1.8° (200 steps/rev) step angle, and a 6.35 mm D-shape shaft. This variant offers a rated current of 3.5 A per phase and a phase resistance of 0.8 Ω, providing strong holding torque (~1.2 Nm) with robust thermal tolerance. It employs high insulation standards (≥100 MΩ @ 500 VDC; 500 VAC for 1 min) and is rated for a temperature rise up to 80 °C, suitable for continuous use in environments from –20 °C to +50 °C.
Features
- High precision 1.8° step angle for accurate control.
- Strong holding torque for mechanical load handling.
- Durable 56mm body for high torque applications.
- Low resistance for efficient power usage.
- Compatible with most bipolar stepper motor drivers.
- 8mm D-shaft for secure mechanical coupling.
