Product Description:

The E42HLHB-LNK-NS-00 is a hybrid stepper motor manufactured by Kollmorgen within the E Hybrid Stepper Motors series. Built for indexing conveyors, pick-and-place heads, and other position-based tasks, the unit translates digital pulse sequences from a stepper drive into incremental shaft motion, delivering dependable open-loop positioning on industrial automation lines. Its mounting flange matches common gearboxes and linear stages, supporting high-torque, low-speed axes that must hold a load while the shaft is stationary.

Electrical performance is based on a rated phase current of 9.8 A flowing through four parallel leads, with a low phase resistance of 0.27 Ω and an inductance of 5.4 mH. At this excitation, the motor develops a holding torque of 18.4 N·m, enabling load retention at standstill without an external brake. Each commanded step advances the rotor by 1.8 degrees, resulting in 200 steps per revolution with ±1.5% accuracy, while the two-stack rotor has an inertia of 0.16 oz-in-s² for predictable acceleration. The motor has a thermal resistance of 1.3 °C/W, Class B insulation rated for 130 °C, an insulation resistance of 100 megohms, and a dielectric rating of 340 VDC. These electrical and thermal components are housed in a NEMA 42 frame that uses Kollmorgen’s SIGMAX flux path to concentrate magnetic energy.

The motor tolerates an axial shaft load of 1780 N and a radial shaft load of 623 N, allowing direct coupling to belt pulleys or pinned sprockets. Cable entry is splash-resistant and routed through a 1/2-inch NPS conduit connector that terminates on an internal board. This connection suits the Heavy Duty NEMA mounting style and helps protect the windings from coolant spray. A smooth shaft is provided for use with press-fit hubs. Continuous operation is supported at ambient temperatures from -20 °C to +40 °C, and the assembly has a mass of 8.26 kg, which contributes to stable mounting and rotor damping.
