Product Description:
Pacific Scientific manufactures the N32HCHJ-LEK-PF-00 for its POWERPAC N Stepper Motors series. The motor converts timed pulse sequences from a controller into discrete angular movement, enabling repeatable indexing, feeding, and pick-and-place duties in automated machinery. This model provides a strong frame and a straightforward mounting interface while retaining simple electronic commutation. Its stepper design supports controlled incremental motion without requiring the commutation system used by a conventional servo motor.
The rotor is built from laminated steel to minimize eddy-current losses, and the stator carries windings matched to a two-stack magnetic circuit. With a holding torque of 8.6 Nm, the energized motor can keep loads stationary, making it suitable for medium-inertia motion axes. Each revolution is divided into 200 full steps based on a precise 1.8° step angle, so each full-step position command corresponds to approximately 0.0314 radians without microstepping. Installation clearance is based on a 3.38 in. square frame, and the housing has a compact length of 133 mm. Heavy-duty face mounting gives the shaft stable support during cyclic indexing on conveyors and small gantries. Step accuracy remains within ±3%, while the straight-through magnetic path helps preserve repeatability as the motor temperature changes during operation.
The coils withstand up to 340 VDC, providing insulation suitable for industrial drive systems. Insulation resistance is rated at 100 megohms when measured under ambient humidity conditions, helping limit current leakage through the winding insulation. The frame follows the NEMA 34 outline, allowing compatible couplings and gearheads to attach without additional adapters. A rear-mounted 1000 LPR incremental encoder shares the double-ended shaft and supplies feedback for applications that require greater positioning accuracy or drive diagnostics. Power enters through a four-lead parallel harness terminated in a System MS circular connector. The straight-key output shaft is supplied without a shaft seal, allowing direct attachment to a clutch or pulley where a sealed interface is unnecessary.
