Product Description:

The H2HNRFA-LNN-NS-00 is a hybrid stepper motor manufactured by Kollmorgen as part of the H Hybrid Motors series. This NEMA-compatible unit combines permanent-magnet and variable-reluctance technology to produce incremental motion for positioning tables, indexers, and light actuators in factory automation. With standard leadwire connections, it fits easily into control panels and other compact motion assemblies. The motor runs in open-loop control with no feedback device, which reduces wiring while still providing consistent holding torque at each commanded step. This layout is well suited to applications that rely on repeatable indexing rather than closed-loop position correction.

The frame follows the NEMA 23 outline, so the front face bolts directly to common 1.86-inch centerline mounting patterns. A body diameter of 2.25 in. keeps the motor compact while still allowing a laminated rotor with enough magnetic energy for medium-torque duty. Each electrical step covers 1.8 degrees, yielding 200 discrete positions per mechanical turn. That increment supports repeatable motion in feeders, slides, and similar mechanisms that need steady step resolution. Positional deviation remains within ±1.5%, a tolerance that suits pick-and-place units and metering valves. Eight individual leads support both unipolar and bipolar drive topologies, giving the motor flexibility across different drive circuits.

For electrical integrity, the stator windings are rated to Class B, 130°C and must withstand a hipot test up to 340 Vdc without breakdown. Insulation leakage is limited to 100 Megohms, which helps reduce the risk of ground faults when the motor is installed near conductive frames. The approved ambient range of -20°C to +40°C supports reliable resistance and torque output in most indoor machine areas. The motor uses a smooth shaft and has no shaft seal, which makes it better suited to clean enclosures where external sealing is not required. Half-stack lamination helps limit drag so the rotor can respond predictably to commanded current changes.
