Product Description:

Kollmorgen’s H41HCFT-LNK-NS-00 is a hybrid stepper motor in the H Hybrid Motors series. The unit converts pulse commands from an indexer or drive into precise angular motion for machine tools, pick-and-place heads, and other positioning axes on factory floors. By combining permanent-magnet and variable-reluctance features, it delivers repeatable step increments that support open-loop positioning tasks in industrial automation.

Its frame size of NEMA 42 sets the bolt circle and shaft dimensions used by heavy-duty NEMA flanges, and the single-stack lamination supports a holding torque of 828 oz-in. Each electrical step corresponds to 1.8 degrees, giving a base resolution consistent with the stated step accuracy. The shaft tolerates up to 400 lb of axial thrust, and its smooth surface eases coupling. A 130 °C Class B insulation system, together with 100 megohms of insulation resistance and a 340 VDC dielectric limit, protects the eight-lead winding. Conductors exit through a system MS connector and mate with an MS3116F14-12S plug. Thermal resistance of 1.8 °C/W helps limit temperature rise during low-speed, high-torque operation.

Side-loading capacity reaches 140 lb at the shaft journal, allowing belt tensions or chain forces to be supported without premature bearing wear. Dynamic behavior is influenced by a rotor inertia of 0.080 oz-in-s², so acceleration profiles remain responsive when combined with microstepping drives. With 200 full-step positions per revolution, the motor produces a coarse resolution that can be electronically subdivided for finer positioning. The assembly weighs 10.9 lb, a mass compatible with gantry axes that must minimize moving loads. Operation is permitted from -20 °C to +40 °C. Continuous service is aided by a winding designed for maximum torque at low speed, which helps maintain torque density across the permitted temperature range.
