Product Description:

The T2HNRHK-LNN-NS-00 is a two-phase hybrid stepper motor manufactured by Pacific Scientific as part of the T High Torque Motors series. It converts pulse commands from a stepper drive into controlled rotary motion, making it suitable for pick-and-place heads, lead-screw stages, and other indexing devices used in automated assembly. The design offers comparatively high static torque from a compact envelope, so precise position holding is possible without adding gearboxes or encoder feedback. Its hybrid stepper layout also supports repeatable incremental motion, which is useful where short moves and consistent stopping points matter more than continuous high-speed rotation.

Dimensional compatibility with the NEMA 23 mounting pattern allows the 56.9 mm body to fit standard motor brackets, while a 41.7 mm stack length keeps mass to 0.5 kg. Each winding conducts 5.3 A DC when fully energized, and the low winding resistance of 0.17 Ω limits copper loss, keeping required phase voltage under 1 V. The 1.8° step angle provides 200 full steps per revolution without microstepping. Static load capacity comes from a nominal holding torque of 0.52 N·m, while detent torque is only 0.014 N·m so the shaft can be repositioned more easily when the drive is disabled. This electrical combination suits current-regulated stepper drives and supports stable indexing during cyclic duty.

Allowable external forces reach an axial load of 111 N and a radial load of 67 N, letting the shaft carry modest belt tension or screw thrust without overloading the bearings. Phase inductance of 0.63 mH supports rapid current transitions when used with a chopper drive, and the rotor inertia of 0.000011 kg·m² helps keep acceleration times short. The two-phase design simplifies connection for either bipolar or unipolar drives. The low inertia-to-torque ratio also helps reduce settling time in small gantry axes and indexing fixtures after short positioning moves.
