Product Description:

The H34HRFP-LNK-NS-00 is a hybrid stepping motor manufactured by Kollmorgen within the H Hybrid Motors series. It couples the high detent capability of a traditional stepper with the smoother micro-stepping profile needed for indexing conveyors, labelers, and vision stages. By translating pulse trains from a drive into mechanical rotation, the motor provides open-loop position control without feedback hardware, and its NEMA footprint lets integrators retrofit existing brackets while gaining improved dynamic torque.

Mechanically, the unit occupies a NEMA 34 frame that is 162.1 mm long with a 73.025 mm pilot and a 98.43 mm bolt circle, matching a heavy-duty mounting style. A 12.7 mm shaft with a 3.175 mm key couples to pulleys, and eight leads emerge through the regular leadwire connection to support unipolar or bipolar drives. Four rotor stacks, a winding optimized for maximum torque at high speed, and a holding capability of 6.47 N·m allow stable load retention at standstill. Each command pulse advances the rotor by 1.8 degrees, giving 200 discrete steps per revolution, and the actual travel stays within the ±1.5% step-accuracy window. A low inertia of 0.247 × 10⁻³ kg·m² shortens acceleration time, while Class B insulation rated to 130 °C, 100 MΩ resistance, and a 340 Vdc dielectric limit protect the windings. Thermal resistance is 1.7 °C/W, so enclosure airflow helps remove heat.

The bearing system endures 801 N of axial thrust and 156 N of radial side load, permitting use with lead screws or overhung belts without reducing service life. Operation remains continuous from -20 °C to +40 °C, aligning with typical cabinet environments. At a mass of 4.40 kg, the motor damps vibration yet stays light enough for moving-gantry axes. The motor supports open-loop motion systems that rely on repeatable step positioning during continuous duty.
