Product Description:

The K33HLFM-LNK-NS-00 is a stepper motor produced by Pacific Scientific within the K PowerPac Motors series. It provides indexed rotary motion for conveyors, pick-and-place heads, and other positioning axes in industrial automation cells. By advancing in fixed angular increments, the motor enables precise open-loop control without requiring encoder feedback. That operating method suits machines that synchronize motion with digital pulse patterns from a step drive and need repeatable start-stop positioning. This makes the unit suitable for compact automation stations with repetitive indexing cycles.

Mechanical configuration centers on a 3.38-inch square frame that follows the NEMA 34 standard and uses a heavy-duty NEMA mounting face. The SIGMAX enhanced construction, laminated rotor, and three-stack stator raise pull-out torque to 15.6 Nm for demanding indexing duties. Overall body length is 171 mm, and the single shaft with a straight key leaves full coupling length outside the housing. There is no shaft seal, so added protection may be needed in washdown areas. The motor uses a 1.8° full-step angle, and positional deviation stays within ±1.5% across the standard ambient range of -20°C to +40°C.

Electrical connection is routed through a 1/2 in. NPSC conduit thread that mates with a splash-proof channel leading to the internal terminal board, helping keep field wiring protected from moisture and debris. The motor is supplied without an encoder, and its phase coils terminate as an 8 lead set that supports both series and parallel drive configurations. Insulation integrity is supported by a value of 100 megohms after high-potential testing, and the windings carry a rating of 340 Vdc for impulse endurance. The motor can be used with standard bipolar step drives, and the conduit connection allows grounding through the frame.
