Product Description:

The H43HCFC-LNK-NS-00 hybrid stepper motor is manufactured by Kollmorgen and belongs to the H Hybrid Motors series. It provides open-loop positioning for indexing tables, conveyors, and pick-and-place axes by translating command pulses into incremental rotation without closed-loop feedback. Its standard construction and heavy-duty mounting pattern support reliable installation on equipment that operates in demanding industrial environments and frequent start-stop cycles. Because the motor is intended for pulse-driven motion systems, it suits applications where position is controlled by commanded step counts rather than encoder signals.

Each revolution is divided into 200 full steps, giving a fundamental step angle of 1.8 degrees; combined with a step accuracy of ±1.5%, this resolution supports repeatable index moves. This step format works well with standard stepper drives and controllers that generate fixed pulse trains. Static holding performance is aided by a detent torque of 70 oz-in, while dynamic inertia remains low at 0.2400 oz-in-s² so acceleration is not limited. The motor uses the NEMA 42 frame, providing a 4.28 in face and a bolt circle of 4.950 in for interchange with existing brackets. A pilot diameter of 2.186 in ± 0.002 in centers the housing, and the 3-stack lamination increases overall length to 10.56 in while maintaining a 0.9 °C/W thermal path.

Class B, 130 °C insulation supports a 340 Vdc rating and maintains 100 MΩ resistance to ground. Eight leads exit through a System MS connector, so series or parallel wiring is possible, and the design omits feedback to keep the connection layout simple. A single smooth shaft with a diameter of 0.7500 in and a length of 2.19 in pairs with couplings or pulleys, and this geometry matches the heavy-duty NEMA face for direct load attachment. Total mass is 25.7 lb, and the motor operates across an ambient range of -20 °C to +40 °C.
