Product Description:

The K32HRHK-LNK-NS-00 is a stepper motor built by Pacific Scientific and supplied under the K PowerPac Motors series. Designed for incremental positioning in industrial automation, the unit converts discrete command pulses from microstepping drives into precise shaft rotation. Its square frame and heavy-duty mounting pattern allow integration in conveyors, index tables, and material-handling axes where open-loop motion control is suitable. Because it is a stepper motor, shaft position follows the commanded pulse count as long as the applied load remains within the motor's available torque.

The motor uses a NEMA 34 frame whose 3.38-inch square geometry matches standard saddles and couplings. Within the housing's 133 mm length, the windings are arranged in a 4-lead parallel circuit so low supply voltage can deliver high phase current. This configuration produces a holding torque of 10.8 Nm, allowing the shaft to resist load torque at standstill without active feedback. Each full step advances the rotor by 1.8°, and compatible microstepping drives can subdivide that increment for smoother motion. The compact body also helps the motor accelerate quickly and maintain stable operation through the mid-speed range.

Enhanced SIGMAX construction uses high-flux laminations to increase torque density while keeping losses low. Electrical integrity is supported by an insulation resistance of 100 megohms at ambient temperature and a dielectric withstand capacity of 340 Vdc, so the windings tolerate typical drive bus voltages. The motor maintains position accuracy within ±1.5% of a commanded step, and that repeatability is preserved across an operating range of -20 °C to +40 °C. It uses regular leadwire connections, a heavy-duty NEMA face mount, a single straight-keyed shaft without a shaft seal, standard windings, a two-stack laminated rotor, and no internal encoder.
