Product Description:

The K32HCHL-LEK-M2-00 is a stepper motor built by Pacific Scientific within the K PowerPac Motors series. As a two-phase hybrid stepper, it converts pulse commands from an indexer or motion controller into discrete angular movement for position control in pick-and-place axes, small conveyors, and similar automated stations. The SIGMAX enhanced construction and heavy-duty mounting let the motor fit directly onto standard gearboxes or brackets without custom adapters, making it a practical drive element for repeatable motion tasks in automated equipment.

Its mechanical envelope follows the NEMA 34 standard and uses a 3.38 in. square frame, so couplings and flanges sized for this pattern line up without modification. Each full step rotates the shaft by 1.8°, which matches indexers that divide the incoming pulse train into 200 steps per revolution. The laminated rotor and two-stack magnetic circuit generate a holding torque of 10.8 Nm, helping the motor resist back-driving when power is applied. Overall body length is 133 mm, giving space for the dual-ended shaft that accepts an encoder on the load side while keeping the opposite straight-key end available for drive components.

The windings use a standard pattern with a 4-lead parallel configuration, so current ratings remain compatible with common microstepping drives while minimizing copper loss. Electrical insulation withstands up to 340 Vdc and has a resistance of 100 megohms to ground, which helps reduce leakage risk in humid environments. Thermal suitability spans -20 °C to +40 °C, allowing continuous duty in unconditioned factory spaces. Position repeatability benefits from a step accuracy of ±1.5%, and the absence of a shaft seal suits applications where washdown is not required. The motor also comes with a System MS connector, encoder mounting provision, and standard winding for closed-loop upgrades when tighter velocity or error detection is needed.
