Product Description:

The N31HRFL-LNK-NS-00 stepper motor is manufactured by Pacific Scientific as part of the POWERPAC N Stepper Motors series. It is intended for indexers, pick-and-place actuators, and other open-loop positioning axes where repeatable incremental motion is required in industrial automation. The unit follows the NEMA 34 dimensional envelope and converts drive pulses into controlled shaft rotation through a simple, rugged motor design. This makes it suitable for applications that need dependable step-by-step movement without adding onboard feedback hardware.

The motor uses a 1.8° step angle, which yields 200 full steps per revolution for consistent angular increments. The shaft provides 4.6 Nm of holding torque, helping resist back-driving while the phase currents remain energized. Electrical insulation is rated at 100 megohms and withstands up to 340 VDC, which helps protect the windings against leakage current and electrical stress in typical control cabinets. Standard windings, a laminated rotor, and a single-stack magnetic circuit support stable detent behavior while keeping the motor responsive. Connection is made through regular leadwires, which allows the motor to be wired directly to a compatible stepper drive.

Mechanical integration uses a 3.38 in. square frame with heavy-duty NEMA mounting, and the body length is 94 mm, so the motor fits compact machine layouts without giving up mounting rigidity. The wiring exits as an 8-lead bundle, enabling either series or parallel phase connections to suit available supply voltage and load characteristics. Position repeatability stays within ± 3% of commanded travel, which is suitable for many conveyors and indexing tables that do not require closed-loop correction. The motor has a single shaft with a straight key and is supplied without a shaft seal, so it should be installed away from direct fluid exposure.
