Product Description:

The N32HRFK-LNS-NS-04 is a stepper motor manufactured by Pacific Scientific as part of the POWERPAC N Stepper Motors series. Designed for open-loop motion in automated pick-and-place systems, indexing tables, and conveyor zones, it converts digital pulse trains into incremental shaft movement without requiring feedback devices. The model belongs to the N-frame family, which emphasizes high torque per frame size while maintaining compatibility with standardized industrial mounts.

Its NEMA 34 housing forms a 3.38-inch square envelope that bolts directly to heavy-duty NEMA flanges, simplifying retrofit work on existing machines. The rotor couples to a single output shaft and advances by a 1.8° electrical step; exactly 200 full steps equal one mechanical revolution. Because of the two-stack magnetic circuit, the motor delivers 8.6 Nm of detent-free holding torque when the phases are fully excited. Overall length is 133 mm, allowing compact installation behind gearheads or timing pulleys. An eight-lead, regular lead-wire exit supports series or parallel coil hookups, so the motor can be wired for either higher torque or higher speed to match drive capability. Step accuracy remains within ±3 percent across the stated load range.

In electrically harsh cabinets, coil isolation is important; this unit exhibits 100 Megohms of insulation resistance under a 500 V test and withstands surge levels to 340 Vdc. Its Laminated rotor core reduces eddy-current heating during rapid starts, and the motor uses Standard construction with a standard winding type used in the POWERPAC N line. The absence of internal encoder feedback simplifies wiring but shifts any required position verification to external sensors. The eight-lead arrangement and 2-stack architecture support unipolar or bipolar-series drive modes without mechanical modification, which helps maintain stable performance in moderate-speed positioning cycles.
