Product Description:
The N42HLEM-LNK-NS-01 is a stepper motor produced by Pacific Scientific for the POWERPAC N Stepper Motors series. Within an automation cell, it indexes mechanical loads in fixed increments, translating drive pulses directly into angular displacement without requiring position feedback. This open-loop operation simplifies wiring and control when moderate speeds and high holding torque are needed on packaging, semiconductor, or material-handling axes.
The motor develops a holding torque of 22.2 Nm, giving fixtures the ability to resist static loads while energized. Each complete revolution is divided into 200 full steps, so the individual step angle is 1.8°, supporting repeatable positioning through microstepping drives. A 4.325 in. square frame fits the NEMA 42 mounting footprint, and heavy-duty bolt patterns let the housing seat firmly against machine plates. Internally, the rotor is laminated and coupled to a single, straight-key shaft to maximize torque transfer. Two stator stacks provide the required magnetic path length, resulting in an overall motor length of 150 mm. Six lead wires arranged in a 6 lead configuration let a drive use series or parallel winding connections.
The electrical insulation system provides an insulation resistance of 100 Megohms and has a dielectric strength of 340 Vdc, allowing the windings to tolerate typical drive bus voltages. Cabling enters through a 1/2 in. NPSC pipe thread conduit port and terminates on a splash-proof board, helping the enclosure stay dry during washdowns. A molded shaft seal blocks coolant or dust from migrating along the journal, and the splash-proof conduit complements the motor’s standard construction code. No encoder is fitted, so position verification must be handled at the system level, but winding balance keeps step error within ±3% of the commanded angle.
