1.8Nm Stepper Motor

The 1.8Nm Stepper Motor belongs to a special line of electric motors featuring standard NEMA 23 (57x57mm) flanges. It functions by converting discrete electrical pulses into rotational motion with a fixed step angle, manufactured from heat-resistant materials, hardened steel shafts, and powder-coated alloy housings. Stepper motors are commonly used in systems requiring high positional accuracy and high torque, such as mini CNC machines, large-format 3D printers, laser engraving machines, automation lines, packaging machines, light industrial robots, and medical equipment.

Overview design of the 1.8Nm Stepper Motor

The 1.8Nm Stepper Motor features a square-body housing with standard NEMA 23 (Size 57) dimensions. Its outer shell is made of die-cast aluminum alloy with a black powder-coated or galvanized anti-rust finish. The motor shaft, with a diameter of 6.35mm or 8mm, is machined with a flat or keyway to enhance grip when installing pulleys or couplings. The rear of the motor integrates a 4-core (or 6-core/8-core) lead wire assembly thoroughly insulated.

Structure of the 1.8Nm Stepper Motor

To ensure precise step resolution and long service life, the 1.8Nm Stepper Motor is constructed from high-grade magnetic materials, divided into two main stationary and moving parts:

• Stator (Stationary part): Assembled from thin silicon electrical steel laminations to reduce eddy currents causing overheating. The magnetic poles are wound with 100% heat-resistant copper wire, arranged scientifically to create a strong rotating magnetic field.
• Rotor (Moving part): Utilizes permanent magnets with a sophisticated serrated grooving design (typically 50 teeth). This structure helps the rotor interact precisely with the stator’s magnetic field, producing decisive step movements.
• Bearing system: Equipped with high-quality deep groove ball bearings at both ends of the shaft, helping reduce rotational friction, withstand radial loads, and increase smoothness during operation.
• Flange: Cast from hard alloy aluminum, precisely machined with screw holes according to the 57mm x 57mm dimensions, facilitating easy mounting onto machine frames.

Applications of the 1.8Nm Stepper Motor

The 1.8Nm Stepper Motor is a 2-phase, 4-wire stepper motor line with a pulling force of 1.8Nm, bridging the gap between the NEMA 17 (too weak) and NEMA 34 (too large) lines, making it a standard and suitable choice for many applications:

• Mini CNC machines and wood routers: Drives the X, Y, and Z axes for wood carving machines and advertising mica cutting machines, ensuring smooth and millimeter-precise cuts.
• Large-format 3D printers: Used for the Z-axis or plastic extrusion mechanism requiring stronger pushing force to prevent printing material clogging.
• Labeling and packaging systems: Accurately controls label positioning on bottles or packaging film pulling at high speeds with precise stopping points.
• Robot arms and turntables: Applied in the joints of pick-and-place robots or indexing turntables, where high repeatability accuracy is required.

The 1.8Nm Stepper Motor is optimized for accuracy, durability, and practical value in automation systems with outstanding advantages: Standard NEMA 23 dimensions for easy replacement and installation. High product lifespan due to the absence of carbon brushes, minimizing maintenance costs for businesses.
