Product Description:

The N42HCLM-LNK-NS-00 is a stepper motor manufactured by Pacific Scientific within the POWERPAC N Stepper Motors series. In industrial automation, it indexes conveyors, pick-and-place heads, and measurement tables by translating command pulses into repeatable mechanical steps. This operating method suits applications that need repeatable motion without a separate feedback device. Its detent and holding characteristics keep loads motionless when current is present, while the heavy-duty NEMA flange lets the motor bolt directly to structural machine frames for holding position when energized and for directly driving large belts or screws.

It uses the NEMA 42 mounting pattern and a 4.325 in. square frame, allowing it to fit equipment built for that motor envelope. Two laminated stacks and standard windings generate 200 full steps per revolution, so the drive can command consistent step movement in an open-loop system. A holding torque of 22.2 Nm maintains axial or radial loads when energized, and an insulation resistance of 100 Megohms supports isolation between the windings and the frame. Cabling enters through a System MS connector that terminates to a four-lead series arrangement, and the motor uses standard construction with a laminated rotor and no encoder.

An insulation test level of 340 Vdc supports operation with high-bus-voltage stepper drives while protecting coil dielectric strength. Overall length is 150 mm, which helps keep the motor compact for its torque class and leaves room for couplings and end hardware in dense machine layouts. The native step angle is 1.8°, and cumulative single-step error is limited to ± 3%, which meets general positioning requirements without microstepping. A single straight-key shaft simplifies coupling to gears or pulleys, and the heavy-duty face helps distribute mounting stress across the machine plate during repeated starts and stops. The motor is intended for clean, dry enclosures because no shaft seal is installed.
