Product Description:

The K42HLLN-LNK-NS-01 is a stepper motor manufactured by Pacific Scientific for the K PowerPac Motors series. As a two-phase device, it advances in discrete increments, making it suitable for open-loop positioning tasks in automated conveyors, pick-and-place heads, and similar equipment where repeatable indexing is required. The large NEMA 42 frame helps dissipate heat, and its size also supports use in applications that require the standard 4.325-inch square mounting format. Because the motor operates without an integrated feedback option, position control depends on commanded step count and available torque margin during operation.

This model develops a holding torque of 28.2 Nm, allowing the shaft to resist load when the drive is energized but not moving. Each full step covers 1.8°, and the laminated rotor with a standard winding set produces this resolution without micro-stepping. Coil insulation tests to 340 Vdc and has an insulation resistance of 100 MΩ, so the motor is suited for typical industrial drive voltages. Continuous service is specified for ambient temperatures from -20°C to +40°C, matching common factory conditions. A heavy-duty NEMA face allows rigid mounting, and the square frame keeps the motor compatible with other size-42 packages.

Connection hardware is routed through a 1/2 in. NPSC conduit entry that feeds a splashproof leadway to the internal terminal board. Power is supplied through a 4-lead series harness, and the open-loop design keeps external wiring straightforward where encoder feedback is not required. Overall stack depth is 150 mm, giving the two magnetic stacks enough room to develop flux while keeping the motor length manageable for machine layouts. Step uniformity is held within ±1.5%, which helps keep angular displacement consistent throughout the speed range. A single shaft with a straight key is protected by a shaft seal, and the motor uses SIGMAX construction with a laminated rotor and splashproof conduit style.
