Product Description:

The N31HRLJ-LNK-NS-01 is a hybrid stepper motor produced by Pacific Scientific within the POWERPAC N Stepper Motors series. The unit converts pulse-train commands from a drive into fixed angular increments, enabling open-loop positioning in material handling tables, indexers, and light assembly axes. Its design follows the NEMA interface convention, allowing installation in standardized frames without mechanical rework.

Mechanical output capability includes a holding torque of 4.6 Nm, which helps prevent shaft movement when the coils are energized and the command stream is idle. Each command pulse advances the rotor by its 1.8° step angle, yielding 200 full steps per revolution for direct angular resolution without microstepping. The laminated rotor sits in a NEMA 34 housing that mates with heavy-duty face mounts, while the motor body length of 94 mm keeps the overall envelope short for equipment with depth restrictions. A single straight-key shaft transfers torque to couplings without set-screw slippage, and the integrated shaft seal helps block contaminants at the bearing point. The standard winding and construction keep the motor straightforward to pair with common stepper drive arrangements.

Electrical isolation is supported by an insulation resistance of 100 Megohms and an insulation system rated for 340 Vdc, so the phase windings can operate with common drive bus voltages while minimizing leakage current. Step position repeatability stays within the motor’s tolerance, with a step accuracy of ± 3%. The 3.38 in. square frame matches NEMA bolt patterns and fits the one-stack motor body used for this model. Four series leadwires exit through a regular leadwire harness, and no feedback encoder is present. This layout suits applications where position is tracked by commanded steps instead of encoder-based correction.
