Product Description:

The H42RCFT-LNK-NS-00 is a hybrid stepper motor produced by Kollmorgen and positioned within the H Hybrid Motors series for precise indexing and speed control in automated equipment. With a 1.8-degree step angle that yields 200 discrete positions per revolution, the unit converts drive pulses into repeatable motion without external feedback. Its standard construction, NEMA 42 frame, and smooth shaft format let machine builders integrate the motor directly into packaging lines, gantry stages, or material-handling axes where deterministic positioning is required.

This motor delivers 11.2 N-m of holding torque, allowing it to maintain position against static process forces when current is applied. The shaft can accept an axial thrust of 400 lb and a radial side load of 140 lb, so couplings, lead screws, or timing pulleys can be mounted without overloading the bearings. A 0.6250 in diameter stainless-steel shaft is supplied in a smooth configuration for press-fit or clamp-type hubs, and the maximum housing length is 8.04 in, allowing the 18.2 lb assembly to fit within deep but narrow machine bays. Two rotor stacks and a winding optimized for maximum torque at low speed raise breakaway force while keeping rotor inertia at 0.16 oz-in-s², which helps limit settling time during index moves.

The stator winding is insulated to Class B, 130 °C, rated for up to 340 Vdc, and verified at 100 megohms of insulation resistance, so drive electronics can energize the phases without breakdown. Heat generated in the copper follows a thermal path of 1.3 °C/W and is dissipated through the frame, supporting ambient service from -20 °C to +40 °C without derating. An eight-lead configuration brought out through a System MS connector simplifies series or parallel phase wiring, while step accuracy of ± 1.5 % keeps accumulated positioning error within tight tolerances.
