This stepper motor can provide direct and precise motions in a 57 mm round design. Permanent magnet and hybrid technologies are used to provide a full range of solutions.

Motor Highlights

- Step angle 1.8°

- 2 phases

- Holding torque up to 1.1 Nm

The 57HY Series 2 Phase Hybrid Stepping Motor adheres to the NEMA23 standard, integrating high precision, strong torque output, and stable operation—making it an ideal drive solution for industrial automation, precision machinery, and intelligent equipment. With a standard step angle of 1.8°, it ensures accurate position control, while its hybrid design combines the advantages of permanent magnet and variable reluctance stepping motors, balancing performance and cost-effectiveness for both commercial and industrial applications.

Advantages

High Precision Positioning

With a standard step angle of 1.8°, the 2 Phase hybrid stepping motor achieves precise position control (no-load step accuracy: ±5%). When paired with a micro-stepping driver, it can further reduce step angle (e.g., 16 micro-steps = 0.1125°), eliminating low-speed resonance and ensuring smooth operation in precision tasks like 3D printing, CNC engraving, and optical equipment.

Strong Torque at Low Speeds

The hybrid design delivers excellent low-speed torque performance—holding torque ranges from 1.2N·m to 2.8N·m, enabling the motor to drive heavy loads (e.g., conveyor belts, robotic arms) without slipping. Even at low speeds (≤500 RPM), it maintains stable torque output, avoiding speed fluctuations.

Motor are available with different winding and mechanical modification to meet specific applications.
