Product Description:

The H41HCFA-LNK-NS-00 is a hybrid stepper motor produced by Kollmorgen within the H Hybrid Motors series. It combines a laminated rotor with standard construction to generate incremental motion for indexing tables, pick-and-place axes, and other position-based tasks in industrial automation. The unit follows NEMA 42 mounting conventions and is supplied without feedback, so position is inferred from commanded step counts rather than from an encoder. This open-loop arrangement is well suited to systems that rely on repeatable step commands for short, accurate indexing moves. Because the motor does not use built-in feedback, the drive system depends on commanded pulses and proper load sizing to maintain expected position.

The motor advances in discrete increments of 1.8 degrees, giving 200 full steps per shaft revolution for predictable positioning. Its NEMA 42 frame pairs with a 4.28 in outside diameter to provide higher torque than smaller motor sizes while remaining compatible with standard heavy-duty NEMA mounts. That combination makes the motor suitable for applications that need substantial holding and running torque in a standardized mount. Electrical protection is supported by a Class B, 130 °C insulation system that withstands winding temperatures reached during extended duty cycles. Step accuracy remains within ±1.5% because the single-stack rotor is precisely machined and centered, and the eight-lead design supports unipolar or bipolar phase wiring for use with different compatible drive circuits.

The motor is rated for ambient operation from -20 °C to +40 °C. It also has an insulation resistance of 100 Megohms and a dielectric withstand capability of 340 Vdc, which support reliable electrical separation during normal use. Power and phase conductors terminate through a System MS Connector, and the mating plug is MS3116F14-12S for standard MIL-spec connection hardware. The connectorized termination keeps the phase wiring organized at the motor body. Heavy-duty NEMA mounting holes and a smooth single shaft simplify coupling to gears or pulleys, while the laminated rotor helps reduce detent torque for finer microstepping. One mechanical stack keeps the axial length short, and the eight discrete leads support flexible motor wiring through the connector.
