Product Description:
The T23NRHK-LNN-NS-00 is a two-phase hybrid stepper motor produced by Pacific Scientific for the T High Torque Motors series. In positioning tables, pick-and-place arms, and compact index drives, the unit converts digital pulse trains from a stepper drive into discrete shaft movements. By providing incremental motion without feedback devices, it simplifies automated axes that demand repeatable low-speed torque.
Its phase windings have a DC resistance of 0.28 Ω at 40 °C, so the driver regulates current rather than voltage to maintain torque as the motor warms. When energized, the windings draw a rated current of 6 A DC per phase, establishing the magnetic flux needed for full-load operation. The winding inductance is 1.5 mH, which limits current rise and allows microstepping controllers to use high slew rates without overshoot. The motor provides a nominal holding torque of 2.68 N·m, allowing it to hold a load in position when command pulses stop and the windings remain energized. Each command step advances the rotor by a 1.8° increment, yielding 200 full steps per revolution for straightforward ratio calculations.
The frame measures 56.9 mm across and 103.1 mm in length, matching NEMA 23 mounting patterns while offering a deeper magnetic stack for higher torque density. Dynamic loads are governed by an axial shaft limit of 111 N and a radial load limit of 67 N, allowing the use of belt or lead-screw couplings without premature bearing wear. A low rotor inertia of 0.0000593 kg·m² supports rapid acceleration, and the detent torque of 0.049 N·m provides minimal static drag when the windings are de-energized. With a mass of 1.5 kg, the motor adds little moving weight to gantry carriages. Its two-phase architecture keeps the drive electronics simple while delivering torque in both directions.
