Product Description:
The N33HCHK-LNS-NS-02 is a stepper motor produced by Pacific Scientific within the POWERPAC N Stepper Motors series. This motor converts digital pulse trains from an indexer or drive into incremental rotary motion for positioning axes, feeders, and pick-and-place stations in industrial automation. It uses a laminated rotor design and a single shaft to deliver discrete movement without onboard feedback devices, allowing open-loop control in applications that require repeatable step accuracy rather than continuous velocity regulation.
The motor generates a holding torque of 12.4 Nm, giving the shaft strong static load capacity when the windings are energized. Each command pulse advances the shaft by 1.8°, so one full revolution equals 200 discrete steps and makes motion resolution easy to calculate in the drive. Electrical insulation is rated at 100 megohms, which helps limit leakage current between the windings and the case. The winding system withstands up to 340 Vdc without dielectric breakdown. Its step accuracy remains within ±3%, and three laminated rotor stacks raise magnetic flux to increase torque density without changing the frame width.
The motor has an overall length of 171 mm. Its square housing follows the NEMA 34 frame code with a 3.38-inch side dimension, so it fits standard heavy-duty mounting flanges used with this frame size. Power conductors use a 4-lead parallel configuration that helps reduce phase inductance for higher-speed operation. Electrical mating is provided through a System MS connector, which gives a secure connection point for the motor leads. The motor uses standard windings and standard construction, and the lack of an encoder means any feedback function must be handled by the external control system. A single shaft supports direct coupling to gearboxes or timing pulleys.
