Nema 23 Stepper Motor 57BYGH56

Description

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.
