Product Description:
The H32NRFA-LDN-NS-00 stepper motor is produced by Kollmorgen within the H Hybrid Motors series. Designed for incremental motion tasks in automated assembly stations, pick-and-place gantries, and indexing tables, the unit transforms digital pulse trains into fixed angular steps, allowing open-loop positioning without feedback. A laminated rotor and dual-stack stator create the detent profile typical of hybrid designs. Its standardized frame supports installation in packaging, semiconductor, and laboratory equipment that uses compatible motor mounts.
Its frame code is NEMA 34, giving it a 3.4-inch flange with a 3.875-inch mounting bolt circle and a 2.875-inch pilot to match common gearheads. The motor develops a holding torque of 445 oz-in, which can restrain medium-inertia loads while the windings remain energized. Each full step advances the shaft by 1.8 degrees, creating 200 discrete positions per revolution with an accuracy of ±1.5%. Dynamic response benefits from a low rotor inertia of 0.017 oz-in-s², reducing settling time after rapid moves. The smooth, non-keyed shaft can sustain an axial thrust of 180 lb. Eight flying leads use 22 AWG wire, measure at least 12 inches long, and support series or parallel coil connections through the standard lead-wire connection style. The dual-stack construction increases torque density while keeping the overall motor length at 3.76 inches.
The stator windings use enamel and slot liners that form an insulation system rated at Class B, 130 °C. The insulation provides 100 megohms of resistance and a dielectric strength of 340 VDC for operation with unregulated bus supplies. Ambient operating temperatures range from -20 °C to +40 °C, allowing the motor to operate near chilled machinery or inside warm enclosures without derating. The bearings support a continuous side load of 35 lb, helping the shaft withstand radial forces from connected equipment. The motor has an overall mass of 5.3 lb, which helps damp vibration while remaining suitable for moving-gantry axes. Its NEMA mounting arrangement allows installation on compatible brackets without adapter plates.
