Product Description:

The P2HNRH-LNN-NS-00 is a two-phase hybrid stepper motor produced by Pacific Scientific for the POWERMAX II P Motors series. It translates pulse trains from a PLC or indexer into discrete 1.8-degree steps, giving packaging lines, labelers, and light actuators dependable open-loop positioning. With NEMA mounting and a compact 40.7 mm body, it slips into small drive stages where incremental motion is needed and ±1.5 % accuracy is acceptable. Its half-stack rotor keeps the moving mass low.

With a holding torque of 0.42 Nm, the half-stack rotor stays locked when pulses stop, while 0.018 Nm of detent torque provides passive indexing without power. Each revolution contains 200 steps, and the inherent 1.8 degrees step angle meets standard automation tolerances. The windings draw 5.2 A per phase, and the low 0.5 mH inductance lets current rise quickly for high pulse rates. A NEMA 23 frame that weighs 0.45 kg carries a single 6.35 mm shaft able to handle 90 N radial and 60 N axial loads. Four parallel leads in a regular leadwire harness minimize voltage drop across the 0.44 Ω coils.

Thermal and electrical limits govern service conditions. The rotor’s low 0.000007 kg·m² inertia enables rapid acceleration with modest drive energy. The motor uses Class B, 130 °C insulation and has a 95 °C surface limit, 340 Vdc dielectric strength, and 100 megohm resistance to contain heat and leakage. Bearings tolerate a 90 N radial load plus 60 N axial load, supported by the single-shaft layout. Stable operation persists from –20 °C to +40 °C, and the two-phase, four-lead design keeps wiring simple for parallel connection. Standard NEMA mounting and half-stack construction suit tight machines where mass and length must remain low.
