Product Description:
The P22NRXD-LNF-NS-00 is a two-phase hybrid stepper motor manufactured by Pacific Scientific and supplied within the POWERMAX II P Motors series. It uses a regular leadwire harness terminated in a receptacle, which allows a quick plug-in connection to a compatible drive. The unit follows a standard construction format and is supplied without an integral feedback device, so it relies on open-loop pulse control for positioning. In automated pick-and-place cells, small indexing tables, or syringe pumps, the motor converts controller pulses into precise incremental shaft rotation that can be coordinated with other motion axes.
Mechanical dimensions align with the NEMA 23 frame class. The body length is 78.7 mm, and a single 6.35 mm diameter shaft extends 20.60 mm beyond the front face with a 12.7 mm usable flat for set-screw couplings. This flat-shaft arrangement and front mounting flange simplify interchange on legacy brackets. With two rotor stacks and a bipolar parallel winding, the motor develops 1.43 N·m of holding torque while detent torque remains at 0.05 N·m, which supports smooth microstepping at low speed. Each winding draws 2.5 A of rated current through D-type coils with a resistance of 2.44 Ω. The motor has a step angle of 1.8 degrees, producing 200 full steps per revolution with ±1.5% accuracy, and the bipolar scheme helps keep mid-range resonance low.
The motor operates reliably in ambient temperatures from -20 °C to +40 °C and has an IP23 rating, so it should be protected from direct water spray. Class B insulation rated to 130 °C supports normal winding temperature rise, and the motor has 100 megohms of insulation resistance with a 340 Vdc withstand voltage. Dynamic response is supported by a rotor inertia of 0.000025 kg·m², which helps the motor respond quickly to commanded step changes. The magnetic circuit has an inductance of 6.2 mH per phase, supporting rapid current control by modern microstepping drives. Total mass is 1.13 kg, and the standard rotor profile helps keep cogging low for tight velocity regulation.
