Product Description:

The H43HCFA-LNK-NS-00 is a hybrid stepper motor produced by Kollmorgen within the H Hybrid Motors series. By combining permanent-magnet and variable-reluctance principles, the unit delivers indexed motion for automated conveyors, gantries, and material-handling axes that need repeatable positioning without an external feedback device. Its heavy-duty NEMA mounting style and standard construction make the motor a direct drop-in for machinery already configured for this frame class in industrial automation cells.

The motor occupies the NEMA 42 frame envelope and develops a holding torque of 16.5 N-m, allowing stiff detent performance when the drive is energized but not stepping. Each full step advances the shaft by 1.8 degrees, giving 200 discrete positions per revolution; this fixed geometry is useful for open-loop microstepping drives. In a parallel connection, it draws 5.0 A/phase, and its 40.8 mH inductance and 1.48 Ω resistance set the electrical time constant for acceleration commands. An eight-lead configuration lets the windings be wired in either series or parallel, and the System MS connector streamlines cable replacement. The insulation is rated Class B (130 °C), with 100 MΩ resistance and a 340 Vdc withstand voltage.

For mechanical loads, the shaft handles an axial thrust up to 1780 N and a radial side load of 623 N; these limits suit belt drives or spur gears mounted on its smooth shaft. A bolt circle of 3.000 in and a 2.186 in pilot diameter align the housing to standard gearboxes, while three lamination stacks increase torque density without extending overall length. Rotor inertia is 0.24 oz-in-s², and the thermal resistance to ambient is 0.90 °C/W. The motor weighs 11.7 kg and can operate continuously from -20 °C to +40 °C without derating.
