Product Description:

The H41HCFB-LNK-NS-00 hybrid stepper motor is manufactured by Kollmorgen as part of the H Hybrid Motors series. It turns incoming step pulses into incremental rotation for indexing tables, pick-and-place arms, and other motion stages that use open-loop positioning. This layout suits motion stages that need repeatable positioning without a separate feedback device. A permanent-magnet rotor and toothed stator produce discrete movement while simplifying control wiring.

Mechanically, the motor is built on a NEMA 42 frame and uses a heavy-duty NEMA face with a 3.000 in mounting bolt circle for direct mounting on compatible equipment. Standard construction and an overall length of 5.61 in keep the package compact, and the shaft can sustain an axial thrust of 400 lb because of its oversized bearings. Dynamic performance is shown by the holding torque of 839 oz-in and a rotor inertia of 0.080 oz-in-s², which supports rapid settling without excessive overshoot. Eight leads exit through a System MS connector, so the single-stack winding may be wired in parallel for higher speed; in that mode, the phase draws 5.3 A, has 0.64 Ω of resistance, and has 12.4 mH of inductance. Parallel wiring is useful when the application needs higher speed from the same motor frame.

In series connection, the motor suits low-speed, high-torque tasks; it draws 2.7 A per phase, has 2.54 Ω of resistance, and has 49.4 mH of inductance. This wiring favors lower-speed output and steady torque production. The winding uses a 1.8 °C/W thermal path, while Class B insulation rated to 130 °C, a dielectric withstand of 340 Vdc, and 100 megohms of insulation resistance support operation from -20 °C to +40 °C. The smooth shaft has a diameter of 0.6250 in and handles a radial load of 140 lb. Step advancement is fixed at 1.8 degrees, which yields 200 increments per revolution with ±1.5% accuracy, and the motor has a mass of 10.9 lb. The shaft dimensions and radial load capacity support couplings and pulleys used on compact motion axes.
