Product Description:

The H41RCFA-LNK-NS-00 is a stepper unit produced by Kollmorgen in the H Hybrid Motors series. It uses a standard construction layout with a single-stack rotor, which keeps the motor compact while supporting precise incremental motion. Wiring is routed through a System MS connector that mates with an eight-lead harness, allowing series or parallel phase connections. A Class B insulation system rated for 130 °C protects the windings, and the motor maintains step accuracy within ±1.5%. Operation is permitted from -20 °C to +40 °C, making it suitable for typical indoor industrial environments.

Built on the NEMA 42 frame, the motor has a 4.25-inch flange, a 3.000-inch bolt circle, and a 2.186-inch pilot with 10-32 UNC-2B mounting holes for direct installation on compatible machine interfaces. Overall length is 5.61 in, and the smooth shaft measures 0.6250 in in diameter with a 1.75 in projection beyond the mounting face for direct coupling. Static torque reaches 5.92 Nm, while rotor inertia of 0.080 oz-in-s² helps moderate resonance at common operating speeds. The full-step angle is 1.8 degrees, and heat is transferred through a thermal path rated at 1.8 °C/W. Electrical insulation resistance is 100 megohms, and the winding insulation withstands 340 Vdc.

For load support, the motor-end bearing tolerates axial force up to 400 lb and side load up to 140 lb, which supports direct belt, pulley, or gear connections without added external supports in many layouts. The motion system is divided into 200 full steps per revolution, providing angular resolution suited to indexing duties and coordinated linear positioning. This combination of bearing capacity and frame size supports applications that place moderate radial and axial demands on the shaft. The assembly weighs 10.9 lb and uses steel laminations that give the motor a rigid large-frame structure for stable installation on gantries, indexers, and other heavy-duty positioning equipment.
