Product Description:

The H33NRFP-LNN-NS-00 is a hybrid stepper motor produced by Kollmorgen within the H Hybrid Motors series. As a closed-loop positioning component, the motor converts discrete drive pulses into controlled rotation for machine axes, dispensers, or indexing tables in industrial automation. Its NEMA mounting interface aligns with common brackets, allowing quick replacement or integration into existing motion stages. Closed-loop stepper operation also helps reduce missed-step risk in applications that cycle through repeated indexing patterns.

This model uses a three-stack rotor for high detent energy, delivering a holding torque of 698 oz-in while maintaining a fundamental step angle of 1.8 degrees. Together with 200 full steps per revolution and ±1.5% step accuracy, this supports repeatable positioning without an external encoder. The frame follows the NEMA 34 standard, so the 0.500-inch pilot and bolt circle match many gearheads. The motor supports an axial load of 180 lb and a radial load of 35 lb, allowing moderate belt tension or thrust loads on the smooth shaft. Its smooth shaft can be coupled to pulleys, couplings, or gear reducers in standard NEMA 34 assemblies. It is wound for maximum torque at higher speeds, and the eight-lead connection permits series or parallel coil wiring to suit different drive voltages.

The motor body measures 5.06 in long and weighs 7.6 lb, resulting in a rotor inertia of 0.025 oz-in-s² that balances acceleration with stable mid-range damping. Heat dissipates at 2.0 °C/Watt, and Class B insulation rated to 130 °C works with 340 Vdc dielectric strength and 100 megohm resistance to protect the windings. This thermal design supports continuous operation when the motor has adequate heat dissipation around the housing. Operation is permitted from -20 °C to +40 °C, and eight 22 AWG conductors exit the regular leadwire connection for series, half-coil, or parallel drive configurations.
