Product Description:
The N31HRLG-LEK-M2-00 is a hybrid stepper motor produced by Pacific Scientific for the POWERPAC N Stepper Motors series. As a stepper motor, it converts discrete electrical pulses into controlled shaft rotation, allowing open-loop positioning in pick-and-place heads, index tables, and similar automation axes. The unit is supplied with a double-ended keyed shaft so an incremental encoder can be added for optional feedback.
This motor generates a holding torque of 4.6 Nm, providing enough static force to keep loads in position while the windings remain energized. Motion resolution is set at 200 full steps per revolution, so the rotor advances one two-hundredth of a turn with each input pulse; in angular terms, each step equals 1.8°. Position repeatability is maintained within ± 3% of a step, which is suitable for most open-loop motion sequences. The frame follows the NEMA 34 standard, so its mounting flange and pilot dimensions match a wide range of gearboxes, linear actuators, and brackets built for that pattern. Regular lead wires are brought out in a 4-lead configuration for connection to a compatible controller.
The housing uses a 3.38 in. square frame and has a total stack length of 94 mm, giving the motor a compact but heavy-duty form. Electrical insulation withstands up to 340 Vdc, while resistance between the windings and ground remains at least 100 Megohms. These values support installation on high-bus-voltage microstepping drives without additional isolation hardware. A laminated rotor helps limit eddy-current losses and improves detent smoothness, and the absence of a shaft seal reduces friction for higher low-speed torque. The motor also includes encoder mounting provision, heavy-duty NEMA mounting, and one-stack construction for use in industrial indexers and material-handling stages.
