60J18100EC-1000-LS 3.5 Nm Closed Loop Stepper Motor - NEMA 24

The 60J18100EC-1000-LS is a 3.5 Nm Closed Loop Stepper Motor in a NEMA 24 frame, rated 5.0 A per phase with 3.5 N·m holding torque. The 100 mm body and 8 mm shaft give it a middle-ground profile between NEMA 23 and NEMA 34, which suits machines that want the torque of a larger motor without its footprint.

closed loop Operation and the 1,000 P/R Encoder

Stepper motors run open loop by design: the drive commands steps and assumes they occur. This assumption fails when load torque approaches the pull-out limit. The motor carries an integrated 1,000 P/R encoder, so the drive continuously compares commanded position against actual rotor position. Missed steps are detected and corrected on the fly, which keeps registration accurate on long production runs.

Current and Heating

Holding torque is specified with rated current at standstill. During operation the 5.0 A winding current generates heat proportional to duty. closed loop control reduces the standing current when the axis is idle, lowering temperature rise compared with an open-loop motor left at full excitation.

Key Specifications

• Frame size: NEMA 24
• Body length: 100 mm
• Phase count: 2-phase
• Phase current: 5.0 A
• Holding torque: 3.5 N·m
• Shaft diameter: 8 mm
• Feedback: integrated 1,000 P/R encoder

Applications

We supply this motor for packaging machinery, factory automation, precision robotic mechanisms, textile and printing machinery, food processing, and automated handling mechanisms. Its 3.5 N·m rating suits conveyor indexing, rotary turrets, and light machining axes where repeatable positioning and a compact frame are both required.

Selection Considerations

Use a closed loop stepper drive that reads the 1,000 P/R encoder and delivers the 5.0 A phase current. Confirm the available torque at your cycle speed, since holding torque is a static value and running torque declines with speed. The 8 mm shaft and NEMA 24 mounting simplify retrofits into existing small-to-medium automation cells.
