Product Description:

The H31NLLT-LNN-NS-01 is a hybrid stepper motor manufactured by Kollmorgen within the H Hybrid Motors series. It translates discrete control pulses into fixed rotational increments for controlled positioning. This operating method suits indexing, labeling, and other motion-position tasks in automated production lines. Its pulse-driven design supports repeatable step movement in basic automation systems that rely on accurate incremental travel.

Its mechanical envelope uses a body diameter of 3.38 in and a pilot diameter of 2.875 in, dimensions that match the NEMA 34 frame standard for installation. The motor provides 1.67 N·m of holding torque for low-speed positioning and static load retention. Each phase carries 2.7 A through a 4-lead series connection and has 1.12 Ω of resistance with 9.3 mH of inductance. Electrical insulation is rated at 340 Vdc and provides 100 MΩ of resistance. The single-stack, standard-construction rotor moves in 1.8-degree increments, giving 200 steps per revolution with a positional error of ±1.5%.

A splash-proof conduit connector routes the leads to an internal terminal board, and the cable entry uses a 1/2 in NPS pipe thread for strain relief and sealing. The motor mounts through a bolt circle of 3.875 in, and the smooth shaft has a diameter of 0.3750 in with a length of 1.25 in for pulleys or flexible couplings. This arrangement helps the motor fit equipment that needs direct shaft coupling and protected lead entry. Continuous service is supported from -20 °C to +40 °C. The winding insulation system is rated Class B, 130 °C during peak duty, which supports operation in washdown-splash areas and light-positioning stations.
