Product Description:
The N42HCHK-LNK-NS-01 is a stepper motor produced by Pacific Scientific as part of the POWERPAC N Stepper Motors series. Designed for incremental motion tasks in conveyors, pick-and-place stages, and indexing tables, the unit turns command pulses into repeatable rotary steps without the need for an encoder. It features standard construction, a laminated rotor, and a single keyed shaft sealed against contaminants. A heavy-duty NEMA mounting flange and a system MS connector simplify installation inside industrial enclosures.
The motor delivers a holding torque of 22.2 Nm, providing high load-holding capability when the stator windings are energized and the shaft is at rest. Each revolution is divided into 200 full steps per revolution, so one input pulse advances the shaft by a fixed 1.8°. Position repeatability is maintained within ± 3% of a step, supporting open-loop control in applications that cannot accommodate feedback devices. The square housing measures 4.325 inches on each side, matching the dimensional envelope of a NEMA 42 frame motor. Power is routed through a 4-lead parallel winding scheme that lowers phase inductance for higher acceleration. Two rotor stacks increase torque density, and a shaft seal helps prevent grease migration into the bearing cavity.
Electrical integrity is reinforced by an insulation resistance of 100 megohms and an insulation system rated for 340 VDC, reducing leakage current when the drive operates from high-voltage micro-stepping amplifiers. The overall unit length is 150 mm, which helps keep cabinet depth modest even with the system MS connector attached. Its frame follows the NEMA 42 standard, allowing the use of couplings, gearboxes, and flange adapters intended for motors in the same size class. Standard windings, a system MS connector, and a straight-key shaft make wiring and mechanical linkage straightforward, while the heavy-duty NEMA face absorbs radial loads from belt tensioners without additional support.
