Product Description:

The H33NREC-LNN-NS-00 is a hybrid stepper motor manufactured by Kollmorgen as part of the H Hybrid Motors series. This NEMA 34 unit blends discrete-step accuracy with high torque density, making it suitable for positioning or speed-indexing duties in pick-and-place mechanisms, small gantries, and packaging lines where closed-loop feedback is unnecessary. It uses a three-stack rotor design to increase magnetic coupling and deliver stable torque across the full step profile while maintaining a compact overall length.

The motor uses six pre-stripped leads routed through a regular leadwire exit, and the wiring can be terminated directly because the minimum conductor size is 22 AWG. Each phase is energized at 7.8 A and has a resistance of 0.29 ohms, which helps limit copper loss during operation. Winding inductance is 1.6 mH, allowing fast pulse rates in step command sequences. Under static excitation, the rotor develops 466 oz-in of holding torque, and each command pulse advances it by 1.8 degrees. The three-stack rotor has an inertia of 0.025 oz-in-s², while full-step accuracy remains within ±1.5%. Class B insulation rated to 130 °C, an insulation resistance of 100 MΩ, and a dielectric strength of 340 VDC protect the windings against thermal and electrical stress.

A smooth shaft transmits motion while providing 200 full steps per revolution. The bearings tolerate 35 lb of radial load and 180 lb of axial thrust, which supports use in compact linear and rotary positioning assemblies. Heat leaves the stator through a 2.0 °C/Watt thermal path, supporting continuous duty within an ambient range of -20 °C to +40 °C when the frame is fastened to a NEMA flange. Standard construction mass is 7.6 lb, and the regular six-lead wiring supports straightforward installation on equipment that uses the same bolt circle.
