Product Description:
The N31HRHG-LNK-NS-00 is a stepper motor manufactured by Pacific Scientific for the POWERPAC N Stepper Motors series. In automated assembly lines and material-handling systems, this motor receives timed current pulses from a dedicated drive to deliver fixed-angle shaft increments without the need for position sensors. Its compact square housing fits mid-range machinery, and the unit is intended to translate digital motion commands into repeatable mechanical rotation for indexing tables, linear actuators, and conveyor positioning tasks.
The motor produces a holding torque of 4.6 Nm from a single electromagnetic stack energized by a standard winding set. Each electrical pulse advances the rotor by 1.8°, so one revolution is completed after 200 full steps, and positional deviation is limited to ± 3% under rated load. The square stator conforms to the NEMA 34 frame class and measures 3.38 inches on each side, while the overall length is only 94 mm, allowing easy integration into panels with limited depth. A laminated rotor core improves magnetic coupling, and the heavy-duty NEMA face mount uses four through holes to align the shaft to gears or couplings. The one-stack layout also helps keep inertia low so rapid start-stop cycles remain consistent.
Electrical insulation supports operation on drives that deliver up to 340 VDC, and resistance between the windings and frame is 100 megohms to limit leakage current during humid operation. Power reaches the coils through a four-lead parallel connection that exits as a regular leadwire bundle, which simplifies wiring to a compatible stepper drive. No feedback device is installed, so position tracking depends solely on commanded step counts. A single shaft with a straight key transmits torque, and the front end is supplied without a shaft seal, making the unit suitable for clean or sealed enclosures.
