Product Description:

The H42HCFA-LNK-NS-00 hybrid motor is manufactured by Kollmorgen within the H Hybrid Motors series. As a two-stack stepper, it converts digital pulse trains into controlled rotational motion for indexers, gantries, and automated actuators. The unit uses a smooth shaft, standard construction, and a heavy-duty NEMA mounting style suited for rigid frames. With a 4.28 in frame diameter, an 8.04 in overall length, and a 2.186 in pilot, it occupies a moderate envelope while still allowing two-stack torque production. Class B insulation rated to 130 °C, 100 megohms of resistance at 340 VDC, and the absence of feedback devices simplify drive selection and wiring.

The chosen frame code is NEMA 42, giving a large rotor cross-section that raises detent torque and permits higher load inertia. Each electrical step advances the shaft by 1.8 degrees, resulting in 200 discrete positions per full revolution; this coarse segmentation supports open-loop positioning without encoders. Position repeatability is held within +/- 1.5 % of a step, an accuracy level adequate for most material-handling and labeling stations. An 8-lead wiring scheme allows either series or parallel phase connection so the same motor can be configured for high torque at low current or reduced inductance for higher-speed operation.

Mechanical integration of that step geometry is eased by a 3.000 in mounting bolt circle and tapped holes with #10-32 UNC-2B threads, giving a direct fit on thick steel plates while maintaining proper concentricity. Power phases exit through a System MS Connector, keeping the eight conductors grouped and strain-relieved during machine vibration. The laminated core tolerates ambient temperatures from -20 °C to +40 °C, enabling full-rated stepping performance in most factory environments.
