Product Description:

The P22NSXA-LNN-NS-02 is a hybrid stepping motor manufactured by Pacific Scientific within the POWERMAX II P Motors series. This NEMA 23 motor converts pulse commands from a drive into incremental rotary motion for indexing tables, pick-and-place heads, and other automation axes that require open-loop positioning. Its role is to deliver repeatable motion in applications where servo feedback is not required.

Electromechanical output begins with a holding torque of 1.39 Nm, which allows the shaft to resist a substantial static load while energized. During power off, the rotor’s detent torque of 0.05 Nm helps limit free rotation caused by vibration or minor external forces. Each electrical step advances the shaft by 1.8 degrees, and the native sequence of 200 full steps per revolution supports positioning repeatability within the quoted +/- 1.5 % step accuracy. The two-phase winding draws 6.5 A per phase at rated current, and this value corresponds to the low 0.42 Ω resistance of the A coil design. Two laminated stacks increase flux density, and this arrangement fits within the NEMA 23 frame while using the standard NEMA face mounting pattern. The standard rotor and receptacle connector simplify installation in indexers and carton-fill sealers that already use step-pulse controllers.

A rotor inertia of 0.000025 kg-m² supports predictable acceleration when the motor is driven by microstep controllers. The low winding inductance of 0.8 mH allows rapid current rise and supports high pulse rates. Continuous duty is permitted over -20 °C to +40 °C, aided by Class B insulation rated to 130 °C, a 100 MΩ insulation resistance, and a 340 Vdc dielectric withstand. The IP23 splash-protected housing measures 78.8 mm in length and weighs 1.13 kg. Standard construction, no feedback devices, and a single 6.35 mm smooth shaft suit applications where simple open-loop operation is preferred.
