Product Description:

The K33HLHJ-LNK-NS-00 is a stepper motor produced by Pacific Scientific within the K PowerPac Motors series. Designed for industrial indexing tables, pick-and-place carriages, and other open-loop positioning systems, it converts pulse commands into precise angular movement. The unit follows a heavy-duty NEMA mounting pattern, so it can attach directly to standardized gearheads, machine brackets, or motion stages without custom adapters or modified mounting plates.

The motor has a basic step angle of 1.8°, yielding 200 full steps per revolution, while cumulative error is limited to ±1.5% for repeatable point-to-point moves in indexing applications. When the coils are energized, the shaft resists up to 15.6 Nm, providing substantial static load capacity at standstill. The frame follows the NEMA 34 envelope, and Pacific Scientific uses SIGMAX construction to shorten the magnetic path and increase torque density within the 171 mm body built from three magnetic stacks. The motor has standard windings with a 4-lead parallel connection that favors lower phase resistance and higher dynamic torque. A laminated rotor works with the single straight-key shaft, and the motor has no shaft seal. Termination is splash-proof through a 1/2 in. NPSC conduit to a protected terminal board, and the no-feedback option omits an encoder for open-loop drive operation.

Electrical insulation withstands up to 340 Vdc and maintains at least 100 Megohms of resistance, limiting leakage current and supporting long-term dielectric stability in industrial service. The ambient range of -20 °C to +40 °C permits operation in unheated enclosures or in machines located near room temperature. A compact 3.38 in. square frame keeps bolt centers consistent with the standard mounting pattern, and the motor should be operated within the stated voltage, insulation, and temperature limits.
