Product Description:
The H42RLFC-LSS-NS-02 is a hybrid stepper motor manufactured by Kollmorgen as part of the H Hybrid Motors series. It converts discrete pulse trains from a stepper drive into incremental shaft movement, enabling controlled indexing in feeders, pick-and-place axes, and light conveyor stations across industrial automation lines. By combining permanent-magnet and variable-reluctance structures, the motor provides the detent torque and positional repeatability expected from hybrid technology. This operating principle allows the shaft to move in predictable increments without requiring a servo-style feedback loop for basic positioning duties.
The motor follows the NEMA 42 frame code, yielding a square housing with a circular frame diameter of 4.28 in. A mounting face diameter of 4.25 in aligns the body to gearboxes, while a bolt circle of 3.000 in positions the four mounting screws. The 2.186 in pilot diameter centers the load and helps maintain alignment between the motor and the driven assembly. Wiring enters a splash-proof terminal board through a 1/2 in NPS pipe-thread conduit connector, and eight leads accommodate full, half, or series configurations across the motor’s two laminated stacks. Insulation is rated Class B, 130 °C with an initial resistance of 100 Megohms, providing suitable dielectric protection for typical drive operation.
The permissible ambient range of -20 °C to +40 °C supports operation on most factory floors without special cooling hardware. A laminated rotor and two-stack magnetic circuit generate the fundamental step angle of 1.8 degrees, and each revolution is divided into 200 discrete positions with a step accuracy of ±1.5%. The insulation system withstands up to 340 Vdc during hipot testing, helping protect the windings from electrical stress. Because no feedback device is fitted, cabling is simpler and the motor can be connected with fewer auxiliary components than an encoder-equipped unit. A smooth shaft also mates easily with clamp-type couplings or pulleys, which suits straightforward power transmission in indexing and conveying systems.
