Product Description:

The P22NRXD-LSN-NS-03 is a two-phase hybrid stepper motor produced by Pacific Scientific within the POWERMAX II P Motors series. Designed for closed-loop positioning tasks in pick-and-place mechanisms, index tables, and small conveyors, the motor converts digital pulse trains into discrete angular motion without requiring an internal feedback device. Standard NEMA mounting and a smooth output shaft allow direct coupling to timing pulleys or lead screws, giving machine builders a compact motion element that operates from low-voltage stepper drives commonly used in industrial automation panels.

The motor’s frame conforms to NEMA 23 dimensions, establishing a 56 mm square face that aligns with widely available gearboxes and brackets. Each electrical phase draws 1.25 A in series wiring, while the copper windings present 24.8 mH of inductance and 4.88 Ω of resistance; these values affect current rise time and drive voltage selection. The winding pattern produces a full-step increment of 1.8 degrees, yielding 200 discrete positions per revolution. Under full energization, the rotor can sustain 1.43 Nm of holding torque, allowing vertical load support or accurate fixturing without powered motion between command updates.

At rest, the motor has a detent torque of 0.049 Nm, which is the torque the rotor resists when all coils are unpowered. When driven in open loop, positional repeatability is maintained within ±1.5% of the commanded angle, a tolerance suitable for feeders and labeling heads that demand consistent incremental moves. Continuous duty is supported across an ambient range of -20 °C to +40 °C; combined with a thermal resistance of 4.5 °C/W and Class B insulation rated 130 °C, this temperature window helps keep winding hot spots below allowable limits during prolonged indexing cycles.
