Product Description:

The H32NRFA-LNF-NS-00 hybrid stepper motor is produced by Kollmorgen for the H Hybrid Motors series. Built on a NEMA 34 frame, it converts digital step commands into precise incremental motion, allowing packaging machines, indexing tables, and metering devices to position loads without feedback in industrial automation. Its standard construction includes a mounting flange that follows the NEMA template, two magnetic stacks, and an eight-lead winding set.

The motor tolerates an axial end load of 801 N and a radial side load of 156 N, so the smooth shaft can carry belts or gears without exceeding the bearing limits. It delivers 3.14 N·m of static holding torque and has a maximum body length of 95.5 mm. The motor weighs 2.40 kg, while its internal inertia of 0.000120 kg·m² supports quick starts and stops. Regular lead wires measuring 22 AWG or larger exit the housing in a potted bundle, and every conductor is at least 304.8 mm long for flexible routing. Step accuracy is ±1.5%, and a thermal resistance of 2.7 °C/W characterizes heat transfer from the coils to the case. The Class B insulation system withstands temperatures up to 130 °C and provides 100 MΩ of resistance to ground, helping prevent electrical leakage during operation under vibration.

The windings sustain impulse potentials up to 340 VDC, and the unit operates within an ambient temperature range of -20 °C to +40 °C without derating. Each input pulse advances the rotor by 1.8 degrees, providing 200 full steps per revolution and supporting straightforward microstepping ratios. The eight leads can be wired in series or parallel to match the current capabilities of the connected drive. The lead-wire arrangement supports routing through drag chains, while the smooth output surface accepts clamping couplings and avoids the stress concentrations associated with a keyway.
