Product Description:

The P22NRXC-LSN-NS-02 is a two-phase stepping motor manufactured by Pacific Scientific for the POWERMAX II P Motors series. It uses standard construction with a NEMA 23 frame and NEMA mounting pattern, giving machinery axes a familiar footprint. Leads exit through a regular leadwire harness, and a receptacle is included for quick disconnects in panel installations. A smooth shaft and C-type windings complete the mechanical and electrical layout, making the unit suitable for positioning tasks in pick-and-place equipment, small conveyors, and general factory automation.

In parallel wiring, the motor delivers a holding torque of 1.43 Nm, providing secure static load capacity when the drive is energized. Each full step advances the rotor by 1.8 degrees, so one full revolution equals 200 discrete positions, which is adequate for mid-range motion loops without microstepping. The parallel winding draws 3.1 A per phase, and it is paired with a phase resistance of 0.78 Ω and an inductance of 3.9 mH, which supports rapid current rise at high step rates. Two rotor stacks and the standard rotor design yield a detent torque of 0.049 Nm, limiting unwanted drift when the drive is unpowered.

When wired in series, the phase current falls to 1.6 A and is paired with a coil inductance of 15.4 mH and a phase resistance of 3.1 Ω; this arrangement favors smoother motion at lower speeds and reduces drive dissipation. Step placement error remains within ±1.5 %, which supports applications such as fixturing tables and inspection rigs. Class B insulation supports winding temperatures up to 130 °C, while the external surface is limited to 95 °C. The motor withstands 340 VDC hipot testing, has an insulation resistance of 100 MΩ, is rated for continuous service from −20 °C to +40 °C, and omits feedback devices to keep cabling simple.
