Product Description:

The Pacific Scientific K32HCHM-LNK-NS-00 belongs to the K PowerPac Motors series and functions as a hybrid stepper motor for incremental positioning tasks in industrial automation. By indexing the rotor in response to pulse trains from a micro-stepping drive, it offers economical motion control for feeders, light presses, and auxiliary axes where servo feedback is not required. The model uses Pacific Scientific’s magnetic design to deliver high torque output in a compact package and support repeatable open-loop motion.

Its rated holding torque reaches 10.8 Nm, allowing the shaft to resist external loads at standstill without supplemental brakes. Each full electrical step advances the rotor by 1.8°, and cumulative position error is limited to ±1.5%, so commanded motion remains within predictable mechanical tolerance. The motor windings are insulated to 100 Megohms at room temperature and have a dielectric withstand capability of 340 VDC, providing a safety margin for typical chopper drives. The motor uses a 4-lead parallel wiring arrangement to reduce phase resistance and maximize dynamic current, and the standard two-stack laminated rotor improves detent performance while keeping inertia low. Because the unit has no feedback option, encoder channels are not required in the control cabinet.

The housing occupies a 3.38 in. square frame that follows the NEMA 34 bolt pattern, and its overall length is 133 mm. Internal SIGMAX enhanced construction boosts flux density while preserving thermal paths, and the heavy-duty NEMA face permits rigid mounting to machinery plates. Operating limits span -20 °C to +40 °C, so the motor can be used in typical factory conditions without derating. Power connections terminate through a System MS connector. A single straight-key shaft transmits torque to couplings, and the lack of a shaft seal means the motor should be installed in relatively dry locations to help protect the bearings.
