Double Output Shaft Stepper Motor 1.26Nm Torque 57BYGH56-SZ for Automation Equipment

This double output shaft stepper motor model 57BYGH56-SZ delivers a holding torque of 1.26Nm in a standard 57mm frame size. Designed as a two-phase hybrid stepping motor, it provides reliable positioning for CNC machines, 3D printers, and other automation equipment. The unique double shaft configuration allows mechanical coupling on both ends, enabling encoder feedback or secondary load attachment without extra brackets. Operating at 24V DC with 10W rated power, this motor fits into existing NEMA 23 setups for straightforward integration.

Features and Construction

The motor combines a robust hybrid stepper design with practical dual-shaft geometry. Its components are sourced to meet consistent performance in industrial environments.

Material and Build

The housing uses aluminium for heat dissipation and structural support. Internal copper windings and steel laminations form the stator and rotor assembly, delivering the 1.26Nm holding torque. The double output shaft extends from both ends, each with a flat for coupling.

Size and Practical Fit

With a 57mm x 57mm faceplate and 56mm body length, this motor matches standard NEMA 23 mounting dimensions. The overall stack length is compact enough for space-constrained machinery while retaining torque output.

Uses and Placement

The motor suits a range of automation applications where precise rotary positioning and dual-shaft access are beneficial.

Event or Professional Use

In professional settings such as CNC routing, pick-and-place machines, and laboratory automation, the double shaft allows simultaneous monitoring and driving from the same motor body.

Everyday Home Use

For hobbyist CNC engravers and 3D printers, this motor provides reliable Z-axis or extruder movement. The extra shaft end can mount a hand knob for manual positioning during setup.

Benefits and Buying Value

The motor offers practical advantages for system builders who need flexibility in coupling without sacrificing performance.

Reuse and Low Maintenance

Hybrid stepper motors require no brush replacements. The sealed ball bearings reduce routine maintenance, and the aluminium housing resists corrosion in typical workshop environments.

Why Choose This Product

Choosing the 57BYGH56-SZ gives you a double-ended shaft in a widely compatible 57mm frame. The 1.26Nm torque covers medium-duty positioning, and the 24V rating simplifies power supply selection in many systems.
