Product Description:

The H33HRFP-LNK-NS-00 is a hybrid stepper motor manufactured by Kollmorgen within the H Hybrid Motors series. It converts indexed pulse commands from a drive into discrete shaft positions, supplying accurate open-loop motion for automated pick-and-place units, small gantries, and labeling stations in industrial automation. By combining permanent-magnet and variable-reluctance principles, the motor provides high torque density while eliminating the need for an external feedback device in applications that accept positional control through step counting.

Mechanical capability starts with a NEMA 34 frame that is 5.33 in long and built in standard construction for heavy-duty NEMA mounts. Three rotor stacks and windings optimized for maximum torque at high speed generate 698 oz-in of holding torque. Each full step advances the smooth shaft by 1.8 degrees, giving 200 steps per revolution with ±1.5% accuracy. A rotor inertia of 0.025 oz-in-s² balances rapid acceleration with position stability, while overall mass is held to 7.6 lb. Eight 22 AWG leads exit through a regular lead-wire connection style, and the minimum lead length is 12 in for straightforward cabinet routing. Additional mechanical features include a smooth shaft to ease coupling, standard heavy-duty mounting flanges, and a winding design aimed at maintaining maximum torque at elevated speeds.

Thermal and electrical limits are set by a winding system rated to Class B, 130 °C, with 100 megohms of insulation resistance and a 340 VDC insulation voltage rating. Overall thermal resistance is 2.0 °C/Watt. The motor operates from -20 °C to +40 °C ambient and supports up to 180 lb of axial thrust plus 35 lb of overhung radial load through its heavy-duty bearing set. An 8-lead configuration allows series or parallel phase wiring.
