Product Description:

The H43HLFC-LSS-NS-03 is a hybrid stepper motor produced by Kollmorgen for the H Hybrid Motors series. Designed for indexers, packaging equipment, and light-duty gantries, the motor converts discrete command pulses from a drive into incremental shaft rotation, allowing control systems to position loads without a separate encoder. By combining high torque at low speed with holding capability when power is applied, it serves as a compact positioning element in automated assemblies.

For connection to plant wiring, the housing is fitted with a splash-protected terminal board reached through a conduit entry tapped for a 1/2 in. NPS pipe thread. This arrangement meets washdown requirements while keeping internal terminations dry. The frame conforms to the NEMA 42 outline, providing a 4.2-inch square mounting face compatible with larger gearheads and couplings. Internal windings use Class B insulation rated for 130 °C. An insulation resistance of 100 megaohms and a withstand rating of 340 VDC help preserve coil integrity against elevated ambient humidity and transient line spikes. No feedback devices are fitted, so the step position is inferred from commanded pulses. Standard construction materials and a smooth shaft simplify coupling to belts or rigid hubs.

Mechanical attachment relies on a heavy-duty NEMA flange that seats on a 3.000-inch bolt circle, and service wiring is routed through an 8-lead cable set to allow full-coil or half-coil drive modes. The three-stack rotor arrangement increases detent flux for higher incremental torque without changing the footprint. Continuous operation is permitted from -20 °C to +40 °C, and the overall length remains within 10.56 in. to fit shallow enclosures. A 1.8-degree step angle combines with a ±1.5% step accuracy to provide exactly 200 steps per revolution, while the smooth shaft end eliminates key stress points in low-inertia couplings.
