Product Description:

The N31HRHK-LNK-NS-00 is a stepper motor built by Pacific Scientific within the POWERPAC N Stepper Motors series. The model converts incremental drive pulses from an indexer or motion controller into fixed angular displacements, making it suitable for conveyor indexing, small gantry axes, and metering pumps where precise open-loop position control is acceptable. Its laminated rotor and standard winding style allow the motor to generate repeatable detent forces while maintaining consistent positioning behavior. Heavy-duty NEMA mounting points let the unit fit common machinery frames without adapter plates.

With a holding torque of 4.6 Nm, the N31HRHK-LNK-NS-00 can sustain static loads during dwell periods without losing registration. Each full step advances the rotor by 1.8°, and the motor completes 200 discrete positions in one revolution, forming a straightforward ratio for drive electronics that issue integer pulse counts. The 3.38-inch square housing corresponds to a NEMA 34 flange, and this standardized footprint sits on a 3.38 in. square frame so the motor aligns accurately with gearboxes or couplings. A single straight-key shaft simplifies torque transmission, and the one-stack lamination package keeps inertia moderate for responsive starts. Standard construction and regular lead wires support straightforward field termination, while the absence of internal feedback reduces wiring complexity.

The motor body measures 94 mm long, permitting installation in cabinets with limited depth while still providing the thermal mass required for continuous duty. Electrical safety is aided by an insulation resistance of 100 Megohms and a dielectric capability rated at 340 VDC, values that accommodate most low-voltage bipolar drives. The motor uses a 4-lead parallel connection, which supports straightforward phase wiring with compatible bipolar drives. This combination supports reliable operation under repetitive pulse trains and helps reduce moisture-related leakage paths.
