Two-Phase Hybrid Stepper Motor Double Output Shaft 1.26Nm for Automation Equipment

This 57BYGH56-SZ stepper motor offers a practical solution for automation systems that require a double output shaft. The dual-shaft configuration allows you to connect loads or encoders on both ends, simplifying mechanical layout in CNC machines, 3D printers, and pick-and-place equipment. With a holding torque of 1.26Nm and a 57mm frame size, it fits standard NEMA 23 mounting patterns. The motor runs on 24V DC and delivers 10W of rated power, making it suitable for moderate torque applications where precision step control is essential.

Features and Construction

Built as a two-phase hybrid stepping motor, the 57BYGH56-SZ combines reliable electromagnetic performance with a compact frame. The double output shaft extends through both ends of the motor, giving you greater flexibility in mechanical coupling and sensor attachment.

Material and Build

The motor uses laminated steel cores and copper windings to generate the magnetic field. Aluminium alloy end caps provide structural rigidity and help dissipate heat during extended operation. The 6.35mm diameter output shafts are made from hardened steel to resist wear from coupling elements.

Size and Practical Fit

The square frame measures 57mm per side, with a body length of 56mm (excluding shafts). This matches the standard NEMA 23 footprint, so it can replace or integrate into existing mounts and brackets. The double shaft extends approximately 20mm from the front and 15mm from the rear, though exact projection may vary slightly.

Uses and Placement

This stepper motor suits a range of automation tasks where dual-shaft access is beneficial. The rear shaft can drive an encoder or act as a manual adjustment point, while the front shaft connects to the load.

Event or Professional Use

Workshops and machine builders use this motor in CNC routers, laser engravers, and small-scale robotics. The double shaft allows for a manual handwheel or an incremental encoder to be attached at the rear, giving operators both control and feedback options.

Everyday Home Use

Hobbyists and makers building custom 3D printers, plotters, or camera sliders will find the dual-shaft design convenient for adding a rotary encoder or a second drive pulley without modifying the motor housing.

Benefits and Buying Value

This motor offers practical advantages in system design and integration. The double shaft eliminates the need for external shaft extensions or adapters, reducing complexity and potential points of failure.

Reuse and Low Maintenance

Stepper motors have a long service life due to brushless construction. With no brushes to wear out, the 57BYGH56-SZ requires only occasional cleaning of the shaft surface and coupling checks to maintain reliable operation.

Why Choose This Product

If your automation project requires a motor that can drive a load and accept an encoder or a handwheel simultaneously, this double-shaft stepper motor gives you that capability in a standard NEMA 23 frame. The 1.26Nm torque and 24V operation are appropriate for many small to medium positioning tasks.
