1.0 N·m closed loop Stepper Motor With Brake – NEMA23, 56 mm, 8 mm Shaft

Short Body, Full closed loop Feedback

The 57J1854EC-1000-LS-SCG is a 1.0 N·m closed loop Stepper Motor with a short 56 mm NEMA23 body and an integrated brake. With a 4.0 A phase current and 1.0 N·m holding torque on an 8 mm shaft, it targets compact positioning where the full-length NEMA23 stack is too long. Lyenwsin supplies it for packaging cells, handling stations, and battery equipment.

Why Feedback Matters at Low Torque

Despite the short stack, the integrated 1,000 P/R encoder provides full closed loop feedback. This is important for a 1.0 N·m motor because the torque margin is small; detecting and correcting step loss keeps the axis accurate on every cycle instead of drifting out of position.

Brake as Standard Equipment

The holding brake locks the shaft when power is removed, protecting vertical and stop-position axes. In battery equipment and handling cells, this keeps workpieces from moving during clamping or unloading steps.

Specification List

• Phase type: 2-phase bipolar
• Frame size: NEMA23 (57 mm)
• Body length: 56 mm
• Holding torque: 1.0 N·m
• Phase current: 4.0 A
• Shaft size: 8 mm
• Integrated encoder: 1,000 P/R
• Brake: integrated holding brake

Application Scope

Well suited to motion control in packaging machinery, desktop CNC systems, robotics, factory automation, textile machinery, printing machinery, food processing, automated handling mechanisms, and precision positioning mechanisms for battery equipment. Low rotor inertia allows quick indexing in multi-station machines. Typical installations include clamp-and-index stations, rotary dials, and small Z-axis lifts where the compact stack leaves room for sensors and tooling.

Notes on Use

Because the frame is NEMA23, heat is dissipated through the flange and the end cap. Mount on a conductive panel, keep the duty cycle realistic, and rely on the encoder feedback rather than over-currenting the motor to raise torque. As your distributor, Lyenwsin can recommend a matching closed loop drive and confirm brake wiring for your supply voltage.
