NEMA 23 Stepper Motor 57BYGH76
The NEMA 23 Stepper Motor 57BYGH76 is a biphasic hybrid motor featuring a 76 mm stack and 1.8° (200 steps/rev) step angle. It supports a rated current of 4 A per phase and phase resistance of 0.7 Ω, producing a strong holding torque of approximately 1.8 Nm. The standard 8 mm D‑shape shaft is ideal for secure mechanical couplings. With insulation of ≥100 MΩ@500 VDC and dielectric 500 VAC for 1 min, plus a thermal rise limit of 80 °C and operating range from –20 °C to +50 °C, it’s well-suited for continuous heavy-duty use.
Features
- High precision 1.8° step angle for accurate control.
- Strong holding torque for mechanical load handling.
- Durable 76mm 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.
