Pacific Scientific developed motion-control products for industrial machinery, including stepper motors, servo motors, and drives. Its product portfolio expanded through internal development and acquisitions, including Sigma Instruments in 1987. Pacific Scientific later became part of Danaher, and its industrial motion products were incorporated into Kollmorgen. The Pacific Scientific brand remained in use for these products until November 2011. Many of its drives and motors remain installed in operating equipment today.
Pacific Scientific drives and motors remain essential components in many industrial automation systems. Although numerous Pacific Scientific product lines are now obsolete, replacing an entire machine may be unnecessary. Wake Industrial supplies new surplus and reconditioned Pacific Scientific automation parts and offers repair services for eligible units.

Supporting Legacy Pacific Scientific Automation Systems
Pacific Scientific produced motion-control products for packaging machines, material-handling systems, CNC equipment, robotics, and other automated machinery. Many of these components continue to operate reliably, but sourcing replacements has become more difficult as older product families have been discontinued.
A failed drive or motor does not always require a complete controls upgrade. Replacing the defective component with a matching unit can reduce installation time, limit programming changes, and avoid the expense of redesigning a working system.
Wake Industrial carries a variety of Pacific Scientific drives and motors for legacy applications. Repair services are also available for many units.
Common Pacific Scientific Product Families
Pacific Scientific’s legacy automation catalog includes SC750 and SC900 servo drives, SCE900 drives, 6410 stepper drives, POWERMAX II M stepper motors, POWERPAC N stepper motors, and S Series brushless servo motors. These components were designed for demanding industrial motion-control applications.

Repairing Pacific Scientific Drives and Motors
Industrial automation parts can fail because of heat, contamination, unstable power, damaged cooling systems, worn components, or prolonged operation. Common warning signs include intermittent faults, unexpected shutdowns, positioning errors, excessive motor heat, and failure to power up.
Repair may be a practical option when a matching replacement is unavailable or when the existing component must be retained for compatibility.
Wake Industrial can help you replace or repair obsolete Pacific Scientific drives and motors used in legacy automation equipment.
