Product Description:
The K32HCHK-LNK-NS-01 is a stepper motor produced by Pacific Scientific and supplied within the K PowerPac Motors series. As a two-stack unit, it converts discrete drive pulses into exact shaft rotation for position or speed control in automated indexing tables, pick-and-place heads, and metering pumps. SIGMAX enhanced construction raises magnetic flux for higher torque density, while a laminated rotor helps keep detent torque consistent. Heavy-duty NEMA mounting and a system MS connector make integration straightforward on machine frames that require a 3.38-inch-class motor. The product is supplied with a straight-key single shaft and an internal shaft seal, which helps protect the front bearings from fine particulates or splash during continuous operation.
The motor delivers a holding torque of 10.8 Nm, allowing mechanical loads to remain stationary when the coils are energized and the shaft is not moving. Each full step advances the shaft by 1.8°, and cumulative position error is limited to ±1.5%, which supports open-loop applications that rely on predictable displacement without encoders. The operating temperature range is -20 °C to +40 °C, so standard factory environments generally do not require special enclosure cooling. Electrical safety is reinforced by an insulation resistance of 100 Megohms, which helps minimize leakage current when the stator is exposed to elevated humidity. Four parallel leads provide low phase resistance for higher-current drive amplifiers, and the windings use the standard temperature class for this series.
The insulation voltage rating is 340 Vdc, which is the maximum conductor potential relative to the laminated core and supports use with high-bus micro-stepping drives. The motor has a 3.38 in. square frame and a NEMA 34 mounting face, giving it a common footprint for couplings and gearboxes. Overall motor length is 133 mm, which helps balance torque output with cabinet depth in compact machinery. The system MS connector routes each phase through tinned contacts, and the 4-lead parallel arrangement helps keep coil inductance low for fast current rise during rapid acceleration.
