Product Description:
The K32HCHJ-LEK-M2-01 stepper motor is produced by Pacific Scientific for the K PowerPac Motors series. It employs a two-phase, standard-wound stator to translate pulse commands into incremental shaft rotation. Pulse-driven control lets the shaft advance in fixed increments, which is useful where the load must stop at known angular positions. This operating method supports repeatable stop positions on assembly stations, light conveyor sections, and other positioning axes in industrial automation.
Built on a NEMA 34 frame, the unit occupies a compact 3.38 in. square frame while mating to heavy-duty NEMA mounting flanges. The SIGMAX enhanced construction increases flux density in the laminated rotor, and the two-stack core delivers a holding torque of 10.8 Nm so loads remain secure when the drive is idle. Each commanded move advances the shaft by 1.8°, and cumulative position error stays within the ±1.5% step accuracy limit. Continuous service is permitted from -20 °C to +40 °C, allowing installation in unconditioned factory zones. Electrical connection uses a System MS circular connector for a compact single-plug interface, and the motor can be wired for low-inductance bipolar drive modes.
The windings carry an insulation rating of 340 Vdc. They exhibit a resistance of 100 Megohms when tested at ambient temperature, which reduces the risk of dielectric breakdown. Overall length is 133 mm, providing space for the encoder interface while keeping the package short for tight equipment frames. The motor uses a double-ended shaft machined for encoder attachment, so auxiliary feedback devices can be added when the axis requires position confirmation. Lead exits follow a 4-lead parallel arrangement, and a straight-key feature transmits torque while a shaft seal restricts dust and fluid ingress at the drive end.
