Product Description:

The H32NREA-LNN-NS-00 belongs to the Kollmorgen H Hybrid Motors series and is a stepper motor intended for direct mounting to NEMA-compatible machine interfaces. By advancing one indexed increment for each command pulse, it supplies predictable position control to feeders, labeling heads, and small gantry axes where closed-loop feedback is not required. Its hybrid construction combines permanent-magnet and variable-reluctance geometries to improve low-speed smoothness and increase detent torque compared with traditional can-stack stepper designs. This operating principle also makes the unit suitable for applications that rely on repeatable open-loop indexing rather than continuous servo correction.

With a 314 oz-in (2.22 Nm) holding torque, the motor provides strong static holding force at standstill. The unit uses a NEMA 34 frame and has a 3.76 in body length while weighing 5.3 lb, which gives it a substantial mechanical package for medium-duty positioning tasks. A 1.8 degree step angle yields 200 full steps per revolution with ±1.5% accuracy, making it suitable for fine incremental moves in indexing systems and transfer mechanisms. Each phase draws 4.0 A through 0.78 Ω coils and uses a six-lead connection that supports common stepper drive wiring methods. Dual stacks increase magnetic stability, and the 0.375 in smooth shaft runs on internal bearings for consistent rotational support during repeated starts and stops. Thermal resistance of 2.7 °C/W supports the Class B insulation system, and the motor has an insulation resistance of 100 MΩ.

Mechanically, the shaft can withstand an 180 lb (801 N) axial load and a 35 lb (156 N) radial load, which allows the motor to work with belt drives, couplings, and thrust-generating mechanisms when the external load is properly aligned. Continuous operation is permitted across an -20 °C to +40 °C operating span, making the unit suitable for typical industrial indoor environments. The insulation system is rated for 340 Vdc insulation rating against transient drive voltages, helping the windings tolerate normal electrical stress from the connected drive. Electrical current changes are moderated by the 4.1 mH phase inductance, which helps smooth phase-current rise and limits rapid current transitions in the windings. These characteristics support stable step response and predictable behavior during pulse-driven positioning.
