Product Description:

The N41HRFL-LNK-NS-00 is a stepper motor manufactured by Pacific Scientific and assigned to the POWERPAC N Stepper Motors series. Designed for incremental motion tasks, it advances the shaft by fixed angles as its windings are sequentially energized, giving precise open-loop positioning for feeders, test fixtures, and light material-handling axes. A heavy-duty NEMA mounting flange lets the motor bolt directly to machinery, so it can drive loads without intermediate adapters or couplings.

The mechanical envelope starts with a NEMA 42 frame that measures a 4.325 in. square frame, while the stack depth is 99 mm, creating a compact but high-torque package. Its laminated rotor and single, straight-keyed shaft transmit up to 11.5 Nm of holding torque at standstill, supporting motion stages that must resist back-driving when power is off. Each electrical step rotates the shaft by 1.8°, and the ±3% step accuracy helps maintain repeatable indexing. The unit uses standard winding wire and has no shaft seal, so installation is intended for clean environments or enclosed housings. A regular lead-wire exit with durable insulation brings conductors out of the frame for connection to drives.

An integral four-phase winding produces 200 full steps per revolution, and the 8 lead configuration allows either series or parallel coil hookups to match different drive current capabilities. The insulation system withstands up to 340 Vdc between windings and frame, and an insulation resistance of 100 Megohms helps prevent leakage that could reduce torque at elevated humidity. Because no feedback device is fitted, the motor relies on commanded step counts for position reference, which is typical in open-loop motion systems. Standard construction materials, a single-stack lamination, and regular lead-wire routing support use in enclosed machinery and other clean operating environments.
