Product Description:

Pacific Scientific manufactures the T23NRHJ-LNN-NS-00 motor as part of its T High Torque Motors series. This two-phase hybrid stepper converts pulse commands into controlled rotation for positioning tasks within automated machines, providing incremental motion without the need for external feedback devices. Its hybrid stepping design supports repeatable indexing in feeders, transfer mechanisms, and other axes that rely on predictable open-loop motion.

The electrical side of the design is centered on a per-phase draw of 3.8 A DC and copper windings that present only 0.64 ohms of resistance at 40 °C, so controller voltage can remain moderate while still supplying useful torque. Coil inductance is rated at 3.9 mH, which affects current rise time and helps smooth commutation. The motor uses 2 phases in a stator arrangement that works with the 1.8° step angle to produce full-step operation. Static holding performance reaches 2.68 N·m, which is suitable for keeping mechanical loads in place while the shaft remains energized. These electrical values influence heating behavior and operating response during continuous duty.

Mechanically, the rotor moment of inertia is 0.0000593 kg·m², allowing rapid acceleration with limited drive power, and each discrete move equals a 1.8° increment for straightforward micro-stepping calibration. The frame measures 56.9 mm wide, 103.1 mm long, and weighs 1.5 kg, fitting applications where mass must be minimized. A 7.94 mm diameter shaft extends 20.6 mm and endures radial loads up to 67 N without excessive deflection, while axial loading tolerance reaches 111 N for thrust-coupled mechanisms. Rotor support is assisted by ball bearings sized for the listed loads, and the low detent torque helps maintain smooth motion when the shaft is back-driven during setup or manual jogging.
