42J1860-417 NEMA17 Stepper Motor - 0.7 N·m, 60 mm

A NEMA17 Stepper Motor with Full-Frame Torque

The 42J1860-417 is a NEMA17 Stepper Motor, the largest 42 mm-frame motor in this range at 60 mm, rated 0.70 N·m at 1.7 A with a 5 mm shaft. It is a 2-phase stepper suited to applications requiring the full torque availability of the NEMA17 frame, such as 3D printers and small laboratory stages.

Max NEMA17 Torque for Printers and Lab Gear

At 0.70 N·m the longer stator stack moves heavier print carriages, dual-extruder heads and microscope-stage loads. The 1.7 A current and 5 mm shaft remain inside the common NEMA17 ecosystem, keeping existing drivers and couplings usable.

Engineering Data

• Frame: NEMA17 (42 mm)
• Body length: 60 mm

• Shaft: 5 mm
• Type: 2-phase, open-loop

3D Printer, Laboratory and Medical Duties

In 3D printers the motor drives X/Y carriages and the extruder with torque to maintain feed without layer shift. In laboratory automation it positions stages and probes with repeatable micro-step resolution. For medical mechanisms that require quiet, precise, low-inertia motion, the low-vibration construction and moderate current make the motor a compatible axis drive.

Performance Notes

Drive at rated current with microstepping for smooth feed. The 5 mm shaft suits standard NEMA17 pulleys and couplings. Because the frame is small, use properly crimped connectors and keep the motor leads short to avoid voltage drop at higher stepping rates.

Choosing the NEMA17 Frame

NEMA17 motors are the standard drive choice for desktop-scale motion. The 60 mm body is the longest in the NEMA17 range, which is why it reaches 0.70 N·m. Designers who need that torque in a compact 3D printer or inspection stage can keep the common 42 mm pattern while gaining the full torque of the frame class.

Selection Considerations

Confirm the operating speed against the torque-speed curve, because the long stator stack delivers its best torque at lower speeds. Provide airflow around the motor on long print or inspection runs to preserve torque. As a distributor, Lyenwsin can supply the motor together with suitable drivers for 3D-printing and instrumentation projects.
