Product Description:

The K32HCHM-LNK-NS-01 is a stepper motor produced by Pacific Scientific as part of the K PowerPac Motors series. Designed for general automation, it converts digital pulse commands from a drive into incremental shaft rotation for machinery that indexes, advances, or controls web tension without closed-loop feedback. This operating method supports repeatable motion from commanded step counts and keeps the motor-and-drive arrangement simple for straightforward positioning tasks.

The motor uses a 3.38 in. square frame and a body length of 133 mm, giving it a compact mounting face with additional depth behind the machine plate. Pacific Scientific SIGMAX construction and a 2-stack lamination produce a holding torque of 10.8 Nm, which helps the shaft resist static load when the phases are energized. Motion is delivered in discrete 1.8° steps, so each command pulse advances the shaft by a fixed angular increment. A laminated rotor, a single output shaft with a straight key, and a shaft seal support direct coupling while helping keep contaminants away from internal parts. The motor uses a 4-lead parallel winding pattern with a System MS connector, and insulation is rated at 100 Megohms to limit leakage in humid conditions. A heavy-duty NEMA mounting face also supports installation with common motor brackets.

The windings are rated for 340 Vdc insulation voltage and can operate in ambient temperatures from -20 °C to +40 °C. Positioning repeatability is held to ±1.5 %, supporting indexing duties even when the motor is supplied without encoder feedback. Compliance with the NEMA 34 frame code gives it mounting geometry that matches many standard drives, gearheads, and machine interfaces. The standard winding arrangement also keeps phase characteristics within the range supported by ordinary stepper drives, which helps simplify electrical matching.
