Product Description:

The K32HCHM-LEK-M2-00 is a stepper motor manufactured by Pacific Scientific and supplied within the K PowerPac Motors series. This motor provides incremental motion control for positioning tables, indexers, and other industrial automation stages that require repeatable open-loop moves without feedback from an encoder. Its SIGMAX enhanced construction concentrates magnetic flux so higher torque can be delivered from a compact 3.38-inch square frame, making the unit suitable for tight machine envelopes and space-limited machine assemblies.

The motor is built on a NEMA 34 frame that measures 3.38 inches on each side and mounts with a heavy-duty NEMA flange. A laminated rotor in a two-stack arrangement, together with standard windings driven through a 4-lead parallel connection, produces a holding torque of 10.8 Nm. Each full step covers 1.8°, and average trajectory error stays within ±1.5%, supporting moderate precision without a closed-loop encoder. Overall length is 133 mm, and the double-ended shaft uses a straight key for positive torque transfer while also providing a mounting provision for a customer-supplied position transducer. The motor has no shaft seal, so installations should protect the bearings from splash zones and similar contamination.

Electrically, the stator insulation withstands up to 340 Vdc and offers an insulation resistance of 100 Megohms at ambient temperature to help guard against leakage currents. Power and sensor conductors terminate on a System MS connector, which keeps the electrical interface compact and helps reduce wiring errors during installation. Continuous operation is specified between -20 °C to +40 °C, and operation outside this range can reduce torque output or shorten insulation life during extended duty. This temperature window suits typical indoor industrial equipment that remains within normal ambient conditions.
