Product Description:

Pacific Scientific manufactures the K32HCHL-LEK-M2-01 in its K PowerPac Motors series. This model is a hybrid stepper motor intended for indexers, pick-and-place axes, and other open-loop motion stages where repeatable incremental rotation is required without closed-loop feedback. Its hybrid design supports precise incremental motion in compact automation assemblies where stable positioning is important.

The motor is wired through a System MS connector and fastens to machinery with a heavy-duty NEMA mounting flange that matches its NEMA 34 frame code. A rigid 3.38 in. square frame houses the SIGMAX enhanced construction and a laminated rotor that boosts flux density while keeping detent torque low. Each full step corresponds to 1.8°. The double-ended shaft accepts an encoder on the rear, while a straight key handles torque transfer at the drive end and a factory-installed shaft seal helps prevent lubricant migration. Internally, the windings follow a standard pattern and terminate in a 4-lead parallel configuration so phase current can be optimized for low-voltage drives. Two rotor stacks raise static torque to 10.8 Nm, allowing the motor to hold heavy loads when power is applied. The insulation system withstands up to 340 VDC between the windings and frame, and the construction supports encoder mounting without additional brackets.

The overall length is 133 mm, offering a compact package for cabinets with limited depth. Insulation resistance measures 100 Megohms at room temperature, which helps limit leakage current during high-potential testing. Operation is specified from -20°C to +40°C, allowing use in unconditioned factory areas. Step accuracy remains within ±1.5%, so commanded index distances stay consistent after long dwell periods. A standard winding type manages thermal rise within this temperature range.
