Product Description:
The K32HCHM-LEK-M2-01 is a stepper motor manufactured by Pacific Scientific for the K PowerPac Motors series. Designed for incremental motion in equipment such as indexers, small conveyors, or pick-and-place stations, it converts pulse trains into discrete shaft positions without closed-loop feedback. Its heavy-duty NEMA mounting face speeds installation on machine frames or gear reducers, making the unit a straightforward drive element within industrial automation. Because it operates as an open-loop motor, command pulses from the controller establish position and speed directly, which helps keep the drive arrangement simple in indexing and feed applications.
Mechanically, the motor occupies a NEMA 34 footprint with a 3.38 in. square frame. Within this envelope, two rotor stacks and SIGMAX-enhanced construction generate a holding torque of 10.8 Nm. Each input pulse advances the shaft by 1.8°, and accumulated positioning error is limited to ±1.5 %, enabling predictable indexing. A double-ended, straight-keyed shaft supports load coupling at one end and rear-mounted accessories at the other, while a laminated rotor helps reduce detent torque and promote smoother step response during motion.
Electrical integrity is rated for 340 Vdc insulation withstand with an insulation resistance of 100 megohms. The standard winding design, combined with a 2-stack core, balances current demand against dynamic torque, and four parallel lead wires support flexible phase connection. Overall motor length is only 133 mm, which helps in space-critical retrofits, and a shaft seal helps protect the bearings when washdown conditions are present. Continuous service is approved from -20 °C to +40 °C. The motor also includes an encoder mounting provision, a system MS connector for field termination, a laminated rotor core, a SIGMAX magnetic path, and a heavy-duty NEMA flange for secure installation in automated machinery.
