Product Description:
The N31HRLG-LNK-NS-00 is a stepper motor manufactured by Pacific Scientific for the POWERPAC N Stepper Motors series. The unit converts command pulses from indexers or PLC-based drive packs into discrete shaft positions, providing open-loop positioning for automated pick-and-place heads, metering pumps, and small conveyance tables. By delivering incremental motion without internal feedback devices, the motor provides reliable positioning for general industrial automation where precise and straightforward rotary control is needed, especially in systems that rely on pulse-driven indexing and repeatable short moves.
Each mechanical turn is segmented into 200 full steps per revolution, a basic resolution derived from a 1.8° step angle in the rotor-stator pair. Step accuracy remains within ±3%, helped by the laminated rotor stack and the standard winding chosen for torque linearity. This resolution supports controlled incremental movement in indexing tasks, feed mechanisms, and light-duty positioning axes. The single-stack magnetic structure yields a static holding force of 4.6 Nm, allowing the shaft to resist load torque when energized. Electrical safety is supported by an insulation resistance of 100 megohms, so leakage currents stay low even in high-humidity production zones. The motor uses a standard construction format suited to general industrial installations.
Integration is simplified by a NEMA 34 frame with a 3.38-inch square face that mates with the heavy-duty NEMA mounting pattern used for this series. The motor has an overall axial depth of 94 mm, leaving space for couplings and guards inside compact enclosures. Power exits through a regular leadwire pigtail that uses 4-lead series wiring, enabling either bipolar-series or unipolar drive schemes. The insulation voltage rating is 340 Vdc, accommodating typical 160 to 320 Vdc bus voltages without breakdown. The single shaft uses a straight key for torque transfer, and because the motor ships without a shaft seal, it should be mounted away from direct fluid exposure. No internal encoder is fitted, so closed-loop verification, if needed, must rely on an external sensor.
