Product Description:

The P2HNRXF-LNF-NS-00 is a hybrid stepper motor produced by Pacific Scientific within the POWERMAX II P Motors series. Intended for incremental positioning and speed control in industrial automation, the motor advances machinery in fixed 1.8-degree steps without requiring an external feedback sensor. Its NEMA-standard frame and lead-wire terminations allow straightforward integration into pick-and-place modules, index tables, and light conveyors where repeatable rotational movement is required. The open-loop design is suitable for applications that need step-based motion with simple wiring.

Under bipolar parallel excitation, the motor delivers a holding torque of 0.42 Nm, and a detent torque of 0.018 Nm resists passive shaft movement. To reach that torque, the windings draw 1.6 A and present 3.8 Ω of resistance with an inductance of 5.1 mH, a combination that influences the electrical time constant and current ripple. Each electrical cycle advances the rotor by 1.8 degrees, so the two-phase design produces 200 full steps per revolution with a specified accuracy of ±1.5%. The half-stack construction reduces rotor inertia to 0.007 × 10⁻³ kg·m², and the single 6.35 mm diameter shaft has a 12.7 mm usable flat length for secure coupler engagement. The motor uses regular lead-wire connections and follows standard NEMA mounting patterns.

The physical envelope is limited to a maximum length of 40.7 mm, and the frame conforms to the NEMA 23 outline for direct installation on compatible stepper mounts. Class B insulation supports winding temperatures up to 130 °C, while surface temperature during operation must remain below 95 °C. The motor operates in ambient conditions from −20 °C to +40 °C, has an insulation resistance of 100 MΩ at 500 V, and carries a 340 Vdc insulation voltage rating. An IP23 protection class allows installation in filtered-air enclosures, and the standard construction without feedback devices simplifies wiring. The single-ended rotor layout supports common couplings used on compact motion axes.
