Product Description:

The K34HCHJ-LNK-NS-00 is a stepper motor produced by Pacific Scientific within the K PowerPac Motors series. It combines SIGMAX enhanced construction with a laminated rotor to increase torque density while keeping detent torque low. The motor mounts through a heavy-duty NEMA face, making it suitable for positioning axes on packaging machinery, pick-and-place gantries, and similar automation stations.

This model delivers a holding torque of 19.6 Nm and advances the shaft in 1.8° increments, so each full revolution is divided into 200 commanded steps. Step commands reach the windings through a four-lead parallel connection that terminates in an MS system connector, simplifying field wiring to bipolar drives. A 3.38-inch square frame encloses the stator, and the mounting pattern aligns with the NEMA 34 standard. Internally, four magnetic stacks and standard windings increase torque without lengthening the motor. Mechanical output passes through a straight-keyed single shaft for positive engagement with a coupling. No shaft seal is fitted, so the host machine must provide suitable protection against contaminants. The unit has no feedback device, allowing open-loop control when paired with a microstepping drive.

The case length is 210 mm, keeping the motor compact relative to its torque rating. Position repeatability remains within ±1.5%, meeting indexing requirements for medium-precision stages. Continuous operation is permitted from -20 °C to +40 °C, while Class F insulation withstands up to 340 VDC between the windings and frame. The insulation resistance is 100 megohms at ambient humidity, providing the dielectric separation needed between energized conductors and the motor housing. The standard winding arrangement supports straightforward connection to a compatible stepper drive. Its open-loop configuration avoids the additional wiring associated with encoder feedback while retaining commanded incremental motion.
