Product Description:

The N43HRFN-LNK-NS-00 is a stepper motor from the POWERPAC N Stepper Motors series manufactured by Pacific Scientific. This eight-lead, single-shaft unit converts indexer or drive pulses into precise mechanical rotation for industrial positioning tasks such as conveyors, pick-and-place heads, or small machine axes. By combining a laminated rotor with standard windings and a heavy-duty NEMA mounting pattern, the motor supplies open-loop motion without requiring encoder feedback or complex servo tuning. That arrangement makes it suitable for applications where repeatable incremental movement is needed from a simple pulse-driven control system.

Its square housing follows the NEMA 42 frame designation and uses a 4.325-inch square frame, allowing it to fit large legacy mounts. With a three-lamination stack, the motor develops a holding torque of 30.6 Nm, which helps it resist motion at standstill. Each revolution is divided into 200 full steps, which corresponds to a basic step angle of 1.8°. Regular lead wires exit the case in a standard construction format, and the eight-lead layout supports series or parallel phase wiring to match available drive current and voltage. The shaft is single-ended with a straight key to transmit torque to couplings, and the motor is supplied without a shaft seal for clean, dry installations.

Electrical insulation is sized for industrial bus voltages, and the windings are rated to 340 Vdc. Leakage resistance reaches 100 Megohms, which helps limit unwanted current flow through the insulation system during extended service. The motor body length of 201 mm provides substantial mass for heat absorption during continuous phase energization, while step accuracy remains within ± 3% of the nominal angle. The motor is intended for open-loop axes in clean, dry mounting locations and for use with appropriately matched stepper drives.
