Product Description:

The K32HRLM-LNK-NS-00 is a stepper motor produced by Pacific Scientific within the K PowerPac Motors series. Designed for incremental motion tasks, the unit converts programmable pulse trains from a drive into discrete rotor positions, enabling accurate indexing of conveyors, pick-and-place slides, and metering valves in automated equipment. It uses stepper motor electromagnetics to deliver bidirectional torque without a closed-loop feedback device, which suits applications that rely on open-loop positioning. This operating method works well on axes where pulse commands control motion directly and the load remains within the available torque margin.

The motor uses a NEMA 34 frame, which corresponds to a 3.38-inch square housing that fits standard heavy-duty NEMA mounting patterns. The square mounting face helps it fit common machine brackets and coupling layouts without unusual adapters. Its overall length of 133 mm and two-stack lamination set provide the active magnetic path for this package size. With 10.8 Nm of holding torque, the shaft can hold a load at standstill without a separate brake. Each full step rotates 1.8°, and the ±1.5% step accuracy supports repeatable positioning by limiting angular deviation from the commanded step. The laminated rotor, SIGMAX construction, and standard windings improve flux density and thermal balance during repeated indexing cycles.

The windings are insulated for 340 Vdc, and the insulation resistance is rated at 100 Megohms to limit leakage during high-potential testing. Continuous operation is permitted from -20 °C to +40 °C, allowing installation in unconditioned enclosures within that ambient range. Power conductors exit through a regular/leadwire harness arranged as a 4 lead series connection. This lead arrangement provides a straightforward electrical interface for compatible stepper drives. The motor is built without a shaft seal and uses a single straight-key shaft for positive coupling. Because it has no feedback device, position verification must be handled externally when the application requires confirmation of actual shaft position.
