Product Description:

The P2HNRDB-LNN-NS-00 is a hybrid stepper motor manufactured by Pacific Scientific for the POWERMAX II P Motors series. In automated stations it converts incoming pulse trains into controlled incremental rotation, providing straightforward position control without feedback circuits. Its compact footprint fits tight equipment envelopes where repeatable indexing, light load transport, or small mechanical actuators are required. Its construction supports economical torque density for laboratory and light-industrial axes that cycle continuously through long shifts.

Its NEMA 23 frame and 40.7 mm body length result from a half-stack, standard construction that limits size while delivering 0.42 Nm of holding torque. A single smooth shaft, 6.35 mm in diameter and 19.1 mm long, is carried by bearings rated for 20 lb radial and 13 lb axial load, and the face follows the NEMA mounting pattern. Winding type B exits through a regular leadwire and is specified for 2.6 A per phase, 0.76 ohms of resistance, and 1.9 mH of inductance when wired in parallel. Class B insulation (130 °C) yields 100 MΩ resistance, a 340 Vdc dielectric limit, and 6.6 °C/W thermal resistance. The standard rotor carries 0.007 × 10⁻³ kg·m² inertia for moderate acceleration demands.

The basic step angle of 1.8 degrees generates 200 full-step positions per revolution, and positional error stays within ±1.5 %. Detent torque is 0.018 Nm, so the shaft exhibits minimal holding force when unpowered, and the motor ships with no feedback device for open-loop drive schemes. Electrical and mechanical limits allow reliable duty in the -20 °C to +40 °C ambient span, with heat flow aided by the parameters outlined earlier. Total mass is only 0.45 kg, which reduces load on miniature slides and simplifies installation.
