Product Description:

The P2HNSXB-LNN-NS-02 hybrid stepper motor is produced by Pacific Scientific for the POWERMAX II P Motors series. It is intended for motion stages that need repeatable incremental travel without an encoder, because the motor is supplied with no feedback. A NEMA mounting style and standard construction help it fit common brackets, while the built-in receptacle connection keeps wiring compact. Open-loop control also makes it suitable for systems that use a stepper drive rather than a servo amplifier.

This motor can hold a load with 0.42 N-m of nominal static torque while drawing a rated phase current of 2.6 A. Electrical losses are moderated by a phase resistance of 0.76 Ω and an inductance of 1.9 mH, values that influence drive sizing and attainable slew rate. Each full step advances the rotor by 1.8°, and step accuracy remains within ±1.5 %. The half-stack lamination design limits the motor length to 40.7 mm and keeps rotor inertia at 0.00000678 kg·m², which supports quick starts and stops. Detent torque is 0.018 N-m, so cogging stays low when the windings are de-energized. Class B insulation with a 130 °C rating, an insulation resistance of 100 MΩ, and a 340 Vdc insulation rating indicate the motor's electrical isolation margin.

Mechanically, the motor uses a NEMA 23 frame, weighs 0.454 kg, and has a smooth 6.35 mm diameter single shaft. The rotor provides 200 full-step positions per revolution, which supports direct coupling to timing pulleys or lead screws in simple motion systems. Load capacity includes a 58 N axial limit and an 89 N radial limit for the bearings. Operation is allowed from -20 °C to +40 °C. Within that temperature range, winding type B supports normal operation, and the motor uses a standard rotor without a shaft seal.
