Product Description:

The H33NLHB-LNN-NS-00 is a hybrid stepper motor produced by Kollmorgen within the H Hybrid Motors series. As a two-phase incremental actuator, it converts command pulses from a drive into precise shaft positions. This operating style makes it suitable for indexing tables, labeling stations, and other industrial automation tasks that require repeatable motion and controlled stopping accuracy. Because motion is created from discrete input pulses, it also suits applications where simple position indexing is preferred over more complex closed-loop servo operation.

The motor follows the NEMA 34 frame convention, allowing direct interchange with other 86 mm square mounts. A holding torque of 4.70 N·m lets the shaft resist static loads without auxiliary brakes. Each full step advances the rotor by 1.8 degrees, so the standard 200-step revolution can be micro-stepped for finer positioning while keeping step accuracy at ±1.5%. The electrical circuit uses a per-phase resistance of 0.55 Ω, and the rated winding current is 5.4 A, so the housing must dissipate the resulting copper losses during operation. Dynamic response is influenced by the phase inductance of 6.8 mH, which affects current rise time and influences how much drive voltage is needed for fast slew rates. Three rotor-stack laminations increase flux linkage, and the smooth shaft modification eases coupling to timing pulleys or inertial loads.

Thermal operation is permitted within an ambient range of -20 °C to +40 °C, and the winding insulation is rated Class B, which allows coil temperatures up to 130 °C before insulation degradation becomes a concern. A body mass of 3.45 kg adds thermal inertia and works with the stated thermal resistance to moderate temperature rise during continuous duty. The insulation voltage rating of 340 Vdc, insulation resistance of 100 MΩ, splash-proof conduit connection, and standard NEMA mounting support use with typical drive electronics, wiring methods, and industrial machine environments. These electrical insulation properties also help separate the windings from the frame and connected hardware during normal installation.
