Are you struggling with inconsistent motion, weak torque, or unreliable performance from your current stepper motors? Precision and power are non-negotiable for successful embroidery automation, CNC machining, or intricate robotics. The fuxing FL57STH56-2804AF (including the FL57STH56-2804AF-10 variant) and FL57STH76-2804AF two-phase bipolar stepper motors are engineered to eliminate these frustrations, providing the dependable, high-torque motion control your projects demand.

Unleash Powerful & Precise Motion Control

These 57mm NEMA 23 stepper motors are designed for robust and accurate positioning. With a precise 1.8° step angle, they ensure extremely fine control over movement, crucial for detailed work. The FL57STH56-2804AF delivers a strong 1.26 Nm (178.6 oz-in) of holding torque, while the FL57STH76-2804AF steps up to an impressive 1.8 Nm (254.9 oz-in). This high holding torque translates directly into greater power to move heavier loads, resist external forces, and maintain position accuracy even under stress, preventing missed steps and ensuring consistent output for your embroidery frames, CNC gantries, or robotic arms.

Built for Durability in Demanding Environments

Beyond raw power, the design of these fuxing stepper motors prioritizes longevity and reliability. Featuring an IP65 ingress protection rating, they are sealed against dust and low-pressure water jets, making them suitable for workshop environments where debris or splashes might be a concern. The Class B insulation further enhances their resilience by protecting against electrical breakdown under varying temperatures. With robust mechanical features like minimal shaft play and high radial/axial force tolerance, these motors are built to withstand the rigors of continuous operation, reducing downtime and maintenance.

Frequently Asked Questions

What are the key differences between the FL57STH56-2804AF and FL57STH76-2804AF motors?
The primary differences are in their physical length, weight, and holding torque. The FL57STH56-2804AF offers 1.26 Nm of holding torque and weighs 0.7 kg, while the FL57STH76-2804AF provides a higher 1.8 Nm of holding torque and weighs 1.0 kg.

What applications are these fuxing stepper motors best suited for?
These motors are ideal for applications requiring high precision and torque, including CNC machinery, 3D printers, robotics, automated assembly lines, laboratory equipment, packaging machines, and various textile machinery like embroidery machines.

How do I ensure these motors are compatible with my existing stepper motor driver?
These are bipolar 2-phase motors. For optimal performance, ensure your stepper motor driver supports bipolar operation and can supply the rated current of 2.8 A and voltage of 2.5 V per phase. If you’re unsure, contact us with your machine model for assistance.

What does the 1.8° step angle mean for my application?
A 1.8° step angle indicates that the motor completes 200 steps per full rotation (360°/1.8°). This fine step resolution allows for highly precise and accurate positioning, crucial for detailed work in applications like embroidery or intricate CNC operations.
