0.5 N·m closed loop Stepper Motor With Brake – NEMA17, 48 mm Body

The Shortest NEMA 17 in the Series

The 42J1848EC-1000-LS-SCG is a 0.5 N·m closed loop Stepper Motor with a compact 48 mm NEMA17 body and an integrated brake. Holding torque is 0.5 N·m at 1.5 A phase current, delivered through a 5 mm shaft with a built-in 1,000 P/R encoder. It is designed for instruments where envelope, mass, and low vibration matter more than torque.

Precision Through Encoder Feedback

The 1,000 P/R integrated encoder gives the drive real-time rotor position. closed loop control suppresses the low-speed resonance and step loss that limit open-loop small steppers, which matters in optical and laboratory stages where a lost step ruins a measurement or a scan.

Brake for Instrument Axes

The integrated brake locks the shaft on power loss. Semiconductor wafer handlers, medical sample feeders, and inspection stages use this to keep the load stationary between operations and during transport.

Target Applications

Suited to semiconductor equipment, medical equipment, laboratory equipment, optical equipment, 3D printers, inspection equipment, pump systems, and factory automation. The low 1.5 A current reduces the thermal load inside enclosed instruments. Typical use cases also include small sample feeders and auto-focus assemblies that run continuously.

Handling and Setup

Keep the 5 mm shaft within its rated radial load; use a flexible coupling for direct drive. Check that the coupling is sized for the 5 mm bore and that the mounted assembly stays balanced at operating speed. When setting up closed loop, confirm encoder direction and home position before enabling the loop. This motor performs best in light, high-accuracy motion chains. As a distributor, Lyenwsin can match it with a suitable low-current closed loop drive and provide wiring support for instrument integration.
