Product Description:

The N43HCLL-LEK-M2-01 is a stepper motor produced by Pacific Scientific within the POWERPAC N Stepper Motors series. Built with standard construction, the unit delivers incremental position control for index tables, gantry axes, and pick-and-place actuators. Its heavy-duty NEMA mounting interface supports installation where a rugged flange is required, and the motor translates pulse commands from a drive into repeatable angular motion without closed-loop feedback.

Mechanically, the motor follows the NEMA 42 form factor and occupies a 4.325 in. square frame, enabling straightforward attachment to common fixture plates. A laminated rotor and standard windings develop a holding torque of 30.6 Nm, sustaining static loads when power is applied. The step angle is 1.8°, so the shaft advances in discrete increments, and with 200 full steps per revolution the cumulative position error stays within the stated ±3% step accuracy. The heavy-duty flange resists deflection, while a double-ended shaft with a straight key accepts couplings on one end and an encoder on the other for applications that need additional feedback hardware. A shaft seal is present to help deter coolant or dust ingress.

Electrical insulation withstands up to 340 Vdc, and insulation resistance measures 100 Megohms at ambient temperature. The housing length is 201 mm, achieved by stacking three rotor-stator sections, and these 3 stacks increase torque without enlarging the frame outline. A four-lead series winding simplifies connection to bipolar drives, and termination is through a system MS connector to reduce wiring time. Encoder mounting provision, a straight-through shaft design, and standard construction support use in conveyors, labeling heads, and other repetitive-motion devices.
