Product Description:

The H22NRFC-LNN-NS-00 is a hybrid step motor manufactured by Kollmorgen and placed in the H Hybrid Motors series. As an open-loop actuator, it translates pulse trains from a motion controller into fixed angular increments, providing predictable positioning for indexing tables, dispensers, and other automation axes that do not require feedback. This operating method suits machinery that benefits from repeatable incremental motion and straightforward control wiring. Because the motor follows incoming pulse counts directly, it is commonly used where the commanded move profile remains consistent throughout the cycle.

Inside a compact housing that follows the industry-standard NEMA 23 footprint, a laminated rotor and a dual-stack stator create 200 discrete positions per revolution. Each command advances the shaft by 1.8 degrees, and cumulative error is limited to ±1.5%. The winding bundle uses an 8-lead cable, so the motor can be connected for parallel, series, or unipolar drive modes without replacing the unit. Regular lead-wire terminations simplify routing inside control cabinets, and the 2.25-inch frame circle supports direct mounting on linear stages and pump heads while helping keep overhang forces low when belt drives or flexible couplings are attached.

The windings are insulated to Class B 130 °C, withstand up to 340 Vdc, and maintain insulation resistance of at least 100 megohms to help limit leakage current. An ambient operating range of -20 °C to +40 °C supports installation in unheated equipment rooms and other enclosed machine spaces with varying temperatures. The shaft is supplied as a smooth shaft, which works well with clamp-style couplings and helps reduce places where debris can collect. There is no shaft seal and no internal feedback device, so applications that need closed-loop verification require an external encoder or another feedback source.
