Product Description:

The E42HLFB-LNK-NS-00 is a hybrid stepper motor manufactured by Kollmorgen within the E Hybrid Stepper Motors series. The unit provides open-loop positioning for packaging lines, indexing tables, and material-handling equipment where repeatable incremental motion is required. By advancing exactly one rotor tooth per command pulse, it delivers discrete angular steps without the need for an external encoder or resolver.

It employs Kollmorgen’s SIGMAX construction to maximize flux density inside a NEMA 42 frame, giving adequate room for the twin laminations characteristic of the two-stack rotor. The heavy-duty NEMA face protects the drivetrain as the assembly withstands axial push loads up to 400 lb and radial side loads up to 140 lb on the 0.6250-inch smooth shaft. An eight-lead cable enters a splash-proof terminal board through a 1/2 in. NPS conduit thread for secure field wiring. Class B, 130 °C insulation surrounds the windings; this system provides 100 megohms of resistance and passes a 340 VDC dielectric test. Heat generated along the 8.04-inch body moves outward at 1.3 °C/W, keeping the coil temperature within its limits. A normal step angle of 1.8 degrees provides fine mechanical resolution without microstepping.

For installation in process lines that experience ambient temperature changes, the motor operates from -20 °C to +40 °C without derating. Acceleration profiles benefit from a rotor inertia of 0.16 oz-in-s², allowing quick starts while still damping overshoot. With 200 discrete full-step positions per turn, the drive enables integer-ratio gearing for conveyor or lead-screw mechanisms. Closed dwell positions remain within a ±1.5% step accuracy band under the rated load. Despite its large frame, the assembly weighs only 18.2 lb, so standard linear stages or gantry carriages can support it without additional reinforcement.
