Product Description:

The P22NSXA-LSS-SS-03 is a hybrid stepper motor produced by Pacific Scientific and supplied within the POWERMAX II P Motors series. Designed for open-loop or indexer-based motion stages, the unit converts discrete pulse commands into incremental rotation for feeders, labelers, and light positioning axes in industrial automation. Its hybrid stepper layout makes it suitable for systems that need predictable step-by-step motion without a full servo control structure.

Its square housing follows the NEMA 23 frame standard, giving mounting compatibility with other 2.3-inch motors in the same size class. The electromagnetic section uses two laminated stacks and winding type A to produce a basic step of 1.8 degrees, which equals 200 steps per revolution. At rated parallel drive, the coils accept 6.5 A and allow the rotor to deliver 1.39 Nm of static holding torque without gear reduction. Positional repeatability stays within ±1.5 % of the commanded step, and receptacle-style connections with the NEMA flange mounting style support straightforward installation. A standard rotor, standard construction, and special encoder and shaft options allow feedback additions or custom couplings while preserving the motor’s general operating behavior.

The electrical insulation supports ambient use from -20 °C to +40 °C, and the windings use Class B 130 °C insulation for thermal endurance. A dielectric withstand of 340 Vdc and an insulation resistance of 100 megohms help protect the drive interface in electrically noisy control cabinets. The composite stator and aluminum frame provide a thermal path of 4.5 °C/W, helping heat move away from the active parts during constant stall duty. The mounting face and special shaft configuration also support integration into guarded enclosures or wash-down shields without changing the motor’s basic installation approach.
