Product Description:

The K32HCHK-LEK-M2-01 is a stepper motor built by Pacific Scientific for the K PowerPac Motors series. The unit uses incremental electromagnetic detents to convert command pulses into controlled shaft rotation, making it suitable for indexing conveyors, pick-and-place stages, and general positioning duties in automated machinery. It advances in discrete motion increments, so the control system can position loads through counted pulse trains rather than continuous feedback correction. This operating principle suits compact automation axes that need repeatable indexing, stable standstill behavior, and straightforward drive electronics.

It mounts on a NEMA 34 flange with a 3.38-inch square face, and the overall body length is 133 mm with two stator stacks that increase magnetic circuit density. The two-stack body also increases active magnetic length without changing the mounting face, which helps the motor fit established machine layouts. The laminated rotor and standard windings provide a holding torque of 10.8 Nm, allowing the axis to resist external loads when pulses are absent. Each full step of 1.8°, with an accuracy of ±1.5%, provides predictable resolution without microstepping. For power connection, a 4-lead parallel connection is supplied, which supports higher phase current at lower supply voltage. The insulation system withstands 340 VDC and provides 100 megohms of resistance to ground for safe isolation during high-potential testing.

A System MS connector provides detachable phase wiring, and the heavy-duty NEMA face permits direct mounting to gearboxes or index tables. Pacific Scientific's enhanced SIGMAX construction increases flux density by adding rare-earth inserts in the stator, which helps limit thermal losses within an ambient range of -20 °C to +40 °C. The motor has a double-ended shaft for encoder mounting and a straight key, and a shaft seal is fitted to help limit dust ingress when an encoder is installed. That arrangement allows the motor to drive the load from one end while reserving the second shaft extension for feedback hardware.
