Product Description:

The H32NRFA-LNN-NS-00 is a two-stack hybrid stepper motor in the H Hybrid Motors series manufactured by Kollmorgen. It translates command pulses into incremental rotation, making it suitable for timing screws, labeling tables, and other stations that demand repeatable angular indexing in industrial automation. Because it moves in fixed step increments, it works well in applications where predictable position changes are more important than continuous closed-loop servo correction. The NEMA mounting pattern fits standard gearheads and brackets, and the regular lead-wire interface connects directly to typical bipolar or unipolar stepper drives.

With a frame size of NEMA 34, the front flange uses a 3.875-inch bolt circle and 0.218-inch through-holes that match common NEMA adapters. The motor supplies 445 oz-in of holding torque, which helps restrain the load while the shaft is stopped and the coils remain energized. Each full step advances by 1.8 degrees, so one revolution is divided into 200 discrete positions before microstepping is applied. Insulation rated at 340 Vdc supports use with high-voltage chopper drives, while Class B insulation materials and 100 Megohms of insulation resistance help the motor withstand normal thermal stress. An eight-lead winding supports series or parallel connection, and the smooth 0.375-inch shaft extends 1.25 inches beyond the 2.875-inch pilot diameter.

Overall length is 3.76 in, which helps the motor fit into compact equipment frames and tightly spaced axis layouts. Factory-attached leads use 22 AWG conductors and extend at least 12.0 inches, giving enough reach for routing inside control enclosures without requiring an immediate connector transition. The step positioning error stays within +/- 1.5 %, which is suitable for open-loop feeders that are later referenced by sensors. Ambient service is allowed from -20°C to +40°C, and the 130 °C winding limit provides thermal margin during continuous duty. The two-stack rotor arrangement increases torque density without changing the NEMA mount, and the smooth shaft avoids keyway-related stress in clamp-style couplings.
