Product Description:

The E32NRHT-LNF-NS-00 is a hybrid stepper motor built by Kollmorgen within the E Hybrid Stepper Motors series. As a two-phase stepping actuator, it converts discrete control pulses from an indexer or drive into precise shaft increments for conveyors, positioning tables, and other motion axes in industrial automation. The motor has a maximum body length of 3.76 in, which provides a compact installation depth while accommodating the larger NEMA 34 frame. Its hybrid design combines permanent-magnet and variable-reluctance operating principles to support controlled incremental motion. The motor is intended for open-loop applications in which each incoming pulse advances the rotor by a consistent angular increment.

Internally, the windings draw 5.2 A per phase, so the drive electronics must supply that continuous current without exceeding the permitted coil temperature rise of the Class B insulation system, which is rated to 130 °C. Electrical response is influenced by a phase inductance of 5.0 mH; this inductance slows the current rise at higher pulse rates and reduces the available torque as speed increases. The rotor completes one revolution after 200 discrete step commands, providing a fixed mechanical resolution for open-loop positioning. An insulation resistance of 100 megohms keeps leakage current low, even when condensation is present. The measured thermal resistance of 2.7 °C/W indicates how effectively the 5.3 lb housing transfers internally generated heat to the surrounding air.

The shaft supports an axial load of 180 lb and a radial load of 35 lb, allowing the smooth shaft to carry moderate belt tension or end-mounted couplings without auxiliary bearings. Each commanded step corresponds to 1.8 degrees, and the drive electronics can rely on a step accuracy of ±1.5% for common indexing tolerances. The insulation system withstands up to 340 VDC between the windings and frame, allowing the motor to operate with compatible high-bus microstepping drives. The two-stack rotor uses SIGMAX construction and a winding optimized for maximum torque at low speed, providing stable force without a gearbox. Four parallel leads exit through a standard lead-wire connection, simplifying installation with compatible NEMA gearheads or mounting brackets. The permitted ambient temperature range is -20 °C to +40 °C, supporting operation in indoor machinery exposed to typical plant temperatures.
