Product Description:

The K34HRHJ-LNK-NS-00 is a stepper motor from Pacific Scientific in the K PowerPac Motors series. It converts command pulses from an indexer or compatible drive into incremental shaft movement for positioning and feed-control duties in packaging, indexing, and conveyor equipment. Its laminated rotor and SIGMAX magnetic construction support high torque density, and the motor is built for heavy-duty industrial service. The design uses an external drive for pulse generation and current control rather than an integrated feedback package. This arrangement is common on feed axes, metering systems, and index tables that need repeatable motion.

The motor uses a NEMA 34 mounting interface with a 3.38 in. square frame, so it fits machine layouts built around that standard size. Rated torque reaches 19.6 Nm, delivered through a straight-key shaft that supports positive coupling to pulleys, gear inputs, or similar drive elements. The body length is 210 mm, and the four-stack rotor increases magnetic interaction without increasing frame width. Power exits through a 4-lead parallel winding arrangement, which helps the drive reach rated current quickly during high step-rate operation. This layout supports strong acceleration response while keeping the motor within a familiar mounting envelope.

Electrical insulation is rated for 340 Vdc, and insulation resistance remains at 100 megohms to limit leakage in humid factory environments. The operating range of -20 °C to +40 °C supports typical indoor industrial conditions, and the basic step angle is 1.8° with cumulative error held within ±1.5%. No feedback device is fitted, so applications that require closed-loop position verification must use an external encoder or another external feedback method. The motor also has no shaft seal, which may require added protection where coolant, dust, or washdown exposure is present. Leadwire routing remains simple because the motor does not include extra feedback cabling or sealing hardware.
