Product Description:

Pacific Scientific’s N34HRFL-LNK-NS-00 is a stepper motor in the POWERPAC N Stepper Motors series. The unit converts discrete drive pulses into controlled shaft rotation, making it suitable for material indexing, positioning tables, and other industrial automation tasks that require open-loop precision. Its NEMA 34 frame allows straightforward installation with standard mounting hardware, while the laminated rotor and straight-key shaft support repeatable torque transfer under cyclic loads. This format is commonly used with pulse-and-direction controls that drive frequent starts, stops, and short indexing moves.

The motor occupies a 3.38 in. square frame, matching NEMA 34 bolt patterns and simplifying mechanical integration. A holding torque of 15.3 Nm helps the shaft resist back-driving during standstill. Motion is resolved in 1.8° increments, giving 200 full steps per revolution, and the stated ±3% step accuracy supports predictable angular placement in open-loop systems. The lead wires can be connected in series or parallel to match drive current and voltage requirements, which gives flexibility when pairing the motor with different stepper drives. Overall length is 210 mm, providing room for a longer magnetic section that increases torque output without making the frame wider.

Electrical insulation is rated for 340 Vdc, and insulation resistance measures 100 Megohms or greater to ground, which helps limit leakage current in humid factory environments. The magnetic core uses 4 stacks, spreading heat through a longer body and supporting steady torque production during repeated indexing duty. A heavy-duty NEMA flange secures the housing against vibration transmitted by belts, couplings, or screw drives. Regular lead-wire construction keeps external wiring straightforward for common stepper drive connections. The motor operates without a shaft seal, so it is better suited to installations where dust and liquid exposure are controlled by the surrounding machine design.
