NEMA17 closed loop Stepper Motor With Brake – 0.7 N·m, 60 mm Body

A Workhorse for Small-Format Equipment

The 42J1860EC-1000-LS-SCG is a NEMA17 closed loop Stepper Motor With Brake rated at 0.7 N·m holding torque and 1.7 A phase current. It uses a 60 mm body, a 5 mm shaft, and an integrated 1,000 P/R encoder, and it carries a holding brake as standard. This frame size is the workhorse of small-format motion equipment, and Lyenwsin supplies it for 3D printers, medical devices, and inspection machinery.

closed loop Control in a Small Package

The integrated encoder closes the position loop, so the motor corrects step loss instead of stalling silently. For a 0.7 N·m motor this is valuable in applications where the mechanical load changes, such as extrusion feeders and print heads, where an open-loop design would need a large torque reserve.

Brake for Safety and Holding

The holding brake holds the shaft with power off. In medical and inspection equipment this prevents a probe or stage from dropping when power is interrupted, and in 3D printers it keeps the build platform from sinking overnight.

Specifications

• Phase type: 2-phase bipolar
• Frame size: NEMA17 (42 mm)
• Body length: 60 mm
• Holding torque: 0.7 N·m
• Phase current: 1.7 A
• Shaft size: 5 mm
• Integrated encoder: 1,000 P/R
• Brake: integrated holding brake

Applications

The motor is specified for packaging machinery, factory automation, precision robotic mechanisms, 3D printers, inspection equipment, pump systems, and medical equipment. Its compact flange and low current make it easy to integrate into control panels with small power supplies.

Mounting Guidance

Use the NEMA17 four-hole flange pattern. Because the body is short, ensure the coupling aligns within the 5 mm shaft tolerance to avoid radial load on the bearings. For brake wiring, verify polarity and supply voltage in the specification before connecting. Lyenwsin offers the matching closed loop drive and cables for a complete small-axis solution.
