Product Description:

The N31HCLK-LNK-NS-00 is a hybrid stepper motor engineered by Pacific Scientific as part of the POWERPAC N Stepper Motors series. As an incremental positioning device, it converts digital pulse trains from an indexer or drive into fixed angular movements, enabling open-loop control of machine axes, labeling heads, or small pick-and-place gantries. The motor follows the NEMA mounting convention, uses laminated rotor construction for higher flux density, and carries a single straight-key shaft so torque can be transmitted directly to couplings or pulleys without additional adapters.

The square frame adheres to the NEMA 34 outline, giving consistent pilot diameters and bolt patterns for heavy-duty brackets. Its holding capability reaches 4.6 Nm, allowing the shaft to maintain position when energized against a static load or gravity. Rotor energization is divided into 200 full steps per revolution, so each step advances the shaft by exactly 1.8°. This discrete angle is the base resolution before microstepping. Mechanical repeatability is controlled within ±3% of a step, limiting cumulative position error in multi-turn moves and removing the need for closed-loop feedback in many indexing applications.

Electrical insulation withstands up to 340 Vdc and leakage remains below 100 Megohms at ambient humidity, helping prevent breakdown when high-voltage drivers are used. Overall body length is 94 mm, so the motor fits compact enclosures while still offering adequate rotor inertia for speed stability. Power and phase conductors terminate through a System MS connector, which simplifies quick exchange on production lines. Internally, the windings are brought out in a 4-lead series arrangement compatible with bipolar constant-current drives. Standard construction, a one-stack lamination design, and the absence of a shaft seal suit the motor to repeatable indoor duty where contamination levels are controlled, while the heavy-duty NEMA face provides rigid alignment to linear stages or belt drives.
