Product Description:

The N31HLLL-LNK-NS-01 is a stepper motor produced by Pacific Scientific for the POWERPAC N Stepper Motors series. In automated machinery, it converts pulse commands from a motion controller into defined shaft increments, providing position control without feedback components. The motor’s laminated rotor and single-stack design keep inertia moderate, making it appropriate for pick-and-place stations, small index tables, and labeling drives. This format suits repeatable indexing tasks where position is determined by pulse count rather than by a separate feedback signal.

Its stator windings are configured in a standard 4-lead series arrangement that suits bipolar drives and are insulated for up to 340 Vdc. Each electrical pulse advances the shaft by 1.8°, yielding 200 full steps per revolution, and cumulative step error stays within ± 3 % under rated load. The laminated rotor interacts with the winding flux to deliver a holding torque of 4.6 Nm at stall, allowing fixtures to remain stationary when power is applied but motion is halted. There is no encoder or resolver, so the drive relies on open-loop current regulation. The motor length is 94 mm, and the winding package follows the manufacturer’s standard type for thermal compatibility with common stepper drives.

Mechanical integration is through a heavy-duty NEMA mounting face that matches the 3.38 in. square frame used for the NEMA 34 size category. A factory-installed shaft seal protects the bearing set from contaminants, and the straight-key, single-shaft profile simplifies coupling. Terminations are routed to a splash-proof terminal board via a conduit port tapped for 1/2 in. NPSC pipe thread, allowing rigid metallic conduit to be attached. The winding insulation system provides 100 Megohms of resistance when tested at ambient conditions, and the stack length is limited to one to maintain compact mass while meeting torque targets. The terminal board keeps connections accessible while supporting fixed conduit routing on the machine.
