Product Description:

The N31HRFG-LSS-M2-02 is a stepping motor produced by Pacific Scientific within the POWERPAC N Stepper Motors series. Supplied as a self-contained electromechanical actuator, the unit converts sequential current pulses from an external drive into controlled angular displacement, making it suitable for indexing tables, winding machines, and other positioning tasks in industrial automation cells. Its pulse-driven operation makes it well suited for applications that require repeatable point-to-point movement rather than continuous speed regulation.

This model completes a full revolution in 200 discrete increments, with each increment equal to a 1.8° step. The fixed geometry between the stator teeth and rotor poles creates this relationship and simplifies open-loop positioning. A laminated rotor core, combined with the magnetic circuit and winding pattern, produces a holding torque of 4.6 Nm, so the shaft can resist mechanical load when power is applied but no motion command is present. Mechanical interfacing follows a 3.38 in. square frame that matches the dimensional envelope of a NEMA 34 mounting face, allowing direct installation in machines already configured for that frame size. Standard construction materials and an integral heavy-duty NEMA flange provide structural rigidity under radial or axial forces that arise during belt or gear coupling.

Electrical insulation is rated at 100 Megohms to limit leakage current between the windings and the motor case, while the system withstands a hipot test potential of 340 Vdc without dielectric breakdown. Connections are brought out through an 8-lead configuration, allowing the windings to be wired in series or parallel for voltage and current matching. Step position repeatability stays within ± 3% of the commanded angle, which helps maintain accuracy during bidirectional moves. Additional features include regular leadwire exits for straightforward cabinet routing, an encoder mounting provision for closed-loop upgrades, and a 94 mm housing length that fits within most motion axes without extending past adjacent hardware.
