Product Description:

The K32HCHJ-LEK-M2-00 is a stepper motor manufactured by Pacific Scientific in the K PowerPac Motors series. In industrial automation, it serves as a torque-dense positioning element, taking digital step commands from a drive and converting them into discrete shaft movement for indexing tables, pick-and-place axes, or process valves where closed-loop feedback is unnecessary. Because motion is produced in fixed step increments, the motor is well suited to applications that use repeatable indexing and predictable loads.

The motor advances one increment every 1.8°, and its step positioning remains within a ±1.5% error band. A holding torque of 10.8 Nm resists back-driving when the controller is idle. It conforms to the NEMA 34 frame class and uses a compact 3.38 in. square frame, which helps it fit standard mounting layouts. Magnetic density is increased by enhanced SIGMAX construction, while the twin-stack layout adds flux without increasing the frame size. The phase coils use a 4-lead parallel connection, which lowers resistance so higher current can be applied during acceleration. System MS connectors simplify wiring, and the standard winding is compatible with most microstepping drives.

A body length of 133 mm helps the motor fit shallow control cabinets. Internal insulation supports operation in ambient temperatures from -20 °C to +40 °C. The motor has an insulation resistance of 100 megohms, and dielectric withstand is rated at 340 Vdc. The laminated rotor helps reduce eddy-current losses, and the double-ended shaft leaves room for an encoder because the flange includes mounting provision for one. A straight key transmits torque to pulleys, and the assembly is supplied without a shaft seal, so external protection is needed where fluids are present. The standard lead style supports straightforward cable routing.
