Product Description:

The H33HRFB-LNK-NS-00 is a hybrid stepper motor built by Kollmorgen for the H Hybrid Motors series. It delivers incremental rotary motion for indexing tables, labeling heads, and other position-controlled axes in automated systems. Standard construction with a smooth shaft supports direct coupling, and the heavy-duty mounting style matches the NEMA 34 bolt pattern commonly used on packaging and pick-and-place frames. Its hybrid stepper design also suits machines that use pulse-driven positioning and require consistent response during repetitive indexing moves.

An end-of-shaft holding torque of 666 oz-in (4.70 Nm) helps the motor resist back-driving under static load, while the rotor's 0.025 oz-in-s² inertia helps limit overshoot during rapid starts. The shaft can tolerate up to 180 lb (801 N) of axial force and 35 lb (156 N) of radial load, so belt tension or end thrust from lead screws will not damage the bearings. Insulated windings are rated to Class B, 130 °C, with 100 MΩ of resistance at room temperature and a 340 Vdc withstand voltage. Eight individual leads exit the housing through a standard lead-wire connection, allowing series or parallel wiring options, and each conductor is 22 AWG with a minimum length of 12 in. The body length is 5.33 in., and the motor weighs 7.6 lb.

Positioning resolution comes from a 1.8-degree step angle, which produces 200 discrete steps per revolution with a step accuracy of ±1.5%. This performance remains stable across an ambient range of -20 °C to +40 °C, allowing the unit to start in cold facilities or run continuously in warm enclosures. The motor uses three internal stator stacks to increase magnetic flux without extending the outer frame. Lead-wire routing keeps connectors out of the work envelope, which is useful where surrounding machine space is limited.
