Product Description:
The T22NRHJ-LFN-NS-00 is a hybrid stepper motor produced by Pacific Scientific within the T High Torque Motors series. It converts digital pulse trains from an indexer or microstepping drive into incremental rotation for positioning tables, pick-and-place heads, and other discrete-motion axes in industrial automation. The design delivers elevated holding performance while retaining the frame compatibility expected for NEMA 23 installations.
The windings draw 4.1 A DC per phase, and their resistance of 0.49 Ω keeps copper losses within typical drive ratings. Electrical energy is stored in an inductance of 2.5 mH, shaping current rise times so the motor can follow high-frequency step commands without overshoot. When the rotor is energized but stationary, the shaft resists motion with a static holding torque of 1.98 N·m. In contrast, the unpowered detent torque is 0.042 N·m, which establishes the breakaway threshold when power is removed. The laminated rotor stack has an inertia of only 0.0000395 kg·m², enabling rapid acceleration between indexes. Each full step advances the shaft by 1.8°, and the two-phase construction supports microstepping schemes that subdivide that angle for finer resolution.
The housing has a length of 77.7 mm, while the square frame measures 56.9 mm across and the motor has a mass of 1 kg. These proportions help minimize the structural load placed on gantries and small motion axes. A ground steel shaft measuring 20.6 mm long terminates in a journal with a diameter of 6.35 mm, allowing direct coupling with standard pinion gears or timing-belt pulleys. The bearings tolerate continuous radial forces of up to 67 N, providing a clear limit when setting belt tension. They also support continuous axial forces of up to 111 N, which must be considered when selecting thrust collars and connected mechanical components.
