NEMA 23 Stepper Motor 57BYGH76

From the shop's description

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.
