Product Description:

The H42HCFT-LNK-NS-00 is a hybrid stepper motor built by Kollmorgen as part of its H Hybrid Motors series. This NEMA-frame device combines permanent-magnet and variable-reluctance technology to supply indexed motion for packaging tables, pick-and-place heads, and other positioning axes in industrial automation. Its design suits applications that require repeatable incremental movement rather than continuous servo feedback. Standard construction, a smooth shaft, and a System MS connector simplify integration, while the heavy-duty NEMA mounting style helps the motor resist reaction torque during rapid stepping.

The motor uses a large NEMA 42 frame, and it provides a holding torque of 11.2 Nm. Each electrical pulse advances the rotor by a 1.8-degree step, so one full revolution is divided into exactly 200 discrete positions, which eases open-loop positioning tasks. Dynamic response is influenced by the rotor inertia, and the specified 0.16 oz-in-s² value helps the shaft accelerate quickly without demanding excessive current from the drive. Two stator stacks and an eight-lead winding allow series or parallel connection, so current and inductance can be matched to the selected microstep drive. A step accuracy window of ±1.5% limits positional deviation without requiring feedback devices.

Thermal and electrical limits govern safe continuous operation. The windings use Class B, 130°C insulation, and the copper circuit can withstand a dielectric test potential of 340 Vdc. Heat travels through the case at 1.3 °C/W, so ambient temperature must remain within -20°C to +40°C to keep the coils below their thermal class. Insulation resistance remains at least 100 MΩ under these conditions to reduce leakage current. The motor weighs 18.2 lb, which adds mechanical damping while still allowing vertical mounting when the supporting structure is adequate.
