Product Description:

The H42RCFA-LNK-NS-00 is a hybrid stepper motor built by Kollmorgen within the H Hybrid Motors series. The unit combines the discrete motion of a stepper with torque characteristics suited for moderate-inertia loads, giving straightforward position control for indexing stations, pick-and-place axes, and compact conveyors. By executing incremental motion on command, the motor integrates easily into automation cells that rely on open-loop pulse trains for rotary positioning. Its hybrid construction also helps the rotor move in repeatable increments while maintaining useful low-speed torque during starts, stops, and short indexing moves.

The motor uses a NEMA 42 frame, so its front face and pilot diameter align with standardized 4.2-inch hardware common on larger positioning tables. A holding torque of 11.7 N-m secures the shaft when the coils are energized, helping resist back-driving on vertical or suspended loads. Each electrical step advances the rotor by 1.8 degrees, and with full-step drive logic this yields 200 discrete positions per mechanical revolution, which simplifies conversion between commanded pulses and angular displacement. The motor uses a Class B, 130 °C insulation system, so the coil wiring can reach this temperature without losing dielectric strength during continuous duty within the published ambient range.

Physical dimensions support straightforward integration. The laminated stack measures 8.04 in long, providing additional magnet volume for higher torque without changing the mounting bolt circle. A smooth shaft ground to 0.6250 in diameter mates with keyed or clamped couplings, and its 2.19-inch extension leaves room for encoders or timing pulleys. The motor operates reliably from −20 °C to +40 °C, which suits most factory environments without auxiliary heaters. Shipping mass is 18.2 lb, so the motor should be properly supported during mounting onto housings or linear stages. This combination of size, shaft geometry, and temperature tolerance fits larger stepper applications that need direct mechanical integration and predictable open-loop motion.
