P22NRXB-LNF-NS-00
The P22NRXB-LNF-NS-00 by Pacific Scientific is a proficient stepper motor upgraded by Powermax II features. It boasts larger bearings offering increased fatigue life and improved load support, and superior heat dissipation through exposed lamination. The P22NRXB-LNF-NS-00 model specifies a 58.4 mm x 58.4 mm rectangular frame in line with the NEMA 23 standard size. It's equipped with a standard NEMA mount, standard B stator winding, and a two-stack rotor, all contributing to its highly regular design. It delivers a notable holding torque of 1.51Nm, either in parallel or series winding, and a detent torque of 4.9 x10-2 Nm for enhanced static torque performance. With 200 rotational steps per revolution, it provides precision in applications like printing. The model uses electrical receptacles for connections, although closed-loop feedback through an encoder is unsupported. Despite the standard rotor design, this motor has less acceleration compared to the low-inertia Powermax variant, featuring a rotor inertia of 2.5×10-5 Kgm2.
