Product Description:

The K32HCHK-LEK-M2-00 is a stepper motor manufactured by Pacific Scientific and listed in the K PowerPac Motors series. As a two-phase actuator, it receives timed current pulses from an indexer or micro-stepping drive and converts them into incremental shaft rotation for positioning tasks in automated machinery. In assembly cells and small conveyors, its discrete step motion provides repeatable positioning without closed-loop feedback. This operating principle makes it suitable for equipment that uses predictable, repeatable travel over short stroke lengths.

The motor uses a NEMA 34 heavy-duty mounting face and fits a 3.38 in. square frame, allowing direct installation in standard brackets. The overall body length is 133 mm, and a 2-stack lamination core increases magnetic output while keeping the package compact. Rated static torque reaches 10.8 Nm, giving the axis holding force when the motor is energized at standstill. Each 200-step revolution is based on a full-step angle of 1.8°, so a basic controller can produce small incremental moves without interpolation. Heat dissipation is aided by SIGMAX enhanced construction, and the laminated rotor works with a standard winding set to reduce detent ripple. Electrical connections exit through a System MS connector, and the shaft is double-ended with a straight key so an encoder can be added at the rear. The motor has no shaft seal and is rated for operation from -20°C to +40°C in enclosed machinery.

Electrical insulation includes a surge withstand of 340 Vdc and an insulation resistance of 100 Megohms, which helps protect the coils when the motor is driven by high-energy bipolar amplifiers. The insulation system also supports reliable operation where drive switching places repeated electrical stress on the windings. The motor uses four-lead wiring for straightforward connection to a compatible drive. Positional accuracy is maintained within ±1.5% per step, limiting cumulative error during long indexing sequences. Consistent step accuracy is useful in indexing tables, feed mechanisms, and other stop-to-stop motion applications.
