Product Description:

The N33HLLM-LNK-NS-00 is a stepper motor produced by Pacific Scientific within the POWERPAC N Stepper Motors series. As a hybrid motor, it translates pulse trains from an indexer or drive into incremental rotary motion. In that role, it turns electrical step commands into repeatable angular increments for controlled positioning. This makes it suitable for positioning tables, pick-and-place heads, and other automated axes used in discrete manufacturing cells.

This unit is built on a NEMA 34 frame with a 3.38 in. square face, providing a standard mechanical envelope for heavy-duty brackets. Each full electrical cycle moves the rotor 1.8°, so one revolution equals 200 discrete steps for straightforward open-loop speed control. A laminated rotor and standard winding support smooth microstepping, and step accuracy is held within ±3%. Static loads can be supported by a holding torque of 12.4 Nm, helping the shaft resist back-driving when power is removed. Standard construction materials insulate the stator, and a 4-lead series connection supports half-coil or full-coil energizing schemes with common bipolar drives. The mounting face follows a heavy-duty NEMA pattern, enabling direct replacement of legacy motors without adapter plates.

Total housing depth is 171 mm, obtained by stacking three rotor-stator sections in line, and the 3-stack layout increases torque without increasing frame width. Power conductors enter through a 1/2 in. NPSC pipe thread conduit and terminate on a splash-proof terminal board. Internal insulation has a resistance of 100 Megohms at ambient moisture levels and is rated for 340 Vdc during high-voltage testing. The motor uses a single straight-key shaft and is supplied without a shaft seal, which reduces friction in dry environments. A no-feedback design eliminates encoders and keeps wiring simpler when open-loop accuracy is sufficient for the machine.
