How to source core components from United States
Read the focus counts before the company names. Servo drives hold the largest counted focus on this page, with a count of 2, followed by encoders and position sensors at a count of 1 and servo motors, planetary gearheads and motion systems also at a count of 1. Behind those headings sit 36 profiles covering the full motion chain, from miniature stepper controllers to roller-screw actuators, so the practical question is rarely whether a part exists here but which tier of supplier, from a Fortune 250 group to a two-product specialist, fits your volumes and support needs.
The drive end of the chain is well covered: Copley Controls in Canton, Massachusetts has made servo drives since 1984 as a subsidiary of Analogic, and ADVANCED Motion Controls designs and builds its drives in Camarillo, California. For feedback, BEI Sensors supplies encoders and position sensors within Sensata's line, US Digital manufactures encoders in Vancouver, Washington, and Dynapar in Gurnee, Illinois adds resolvers and condition monitoring. On the motor side, Bodine Electric in Peosta, Iowa has built fractional-horsepower gearmotors since 1905, Groschopp designs and assembles its motors at a single plant in Sioux Center, Iowa, and Empire Magnetics in Rohnert Park, California builds stepper and servo motors for vacuum, cryogenic, radiation and other extreme environments where standard motors fail. Parker Hannifin's Parker Motion range, Kollmorgen in Radford, Virginia and Rockwell Automation in Milwaukee represent the large-group end of the same market, while mjbots and ODrive Robotics serve researchers and builders who buy controllers and actuators directly online.
A workable route through this page is to fix the interface first: torque, feedback type and controller protocol decide which of these suppliers can even quote. On GlobleMatch you can post a sourcing request free of charge with the motor, drive and encoder specifications stated together, matching suppliers answer against the whole motion chain rather than a single part number, and introductions are chosen by fit and never sold. That matters in a category where a drive from one maker, a motor from a second and an encoder from a third still have to work as one axis.
What to check before you contact
- Several profiles are brands or divisions of listed groups, including Parker Hannifin (NYSE: PH), Kollmorgen and Thomson within Regal Rexnord, and BEI Sensors within Sensata, so confirm which entity you would contract with.
- Founding years run from 1903 (Rockwell Automation) and 1905 (Bodine Electric) to 2011 (Helix Linear Technologies), a useful first check on how established a product line is.
- Scale figures are company-stated: Rockwell Automation states approximately 26,000 employees as of fiscal year end 2025, and Groschopp states approximately 200 employees, so check whether that scale matches your volume expectations.
- For harsh environments, Empire Magnetics specialises in motors for vacuum, cryogenic, radiation-hardened, waterproof and hazardous-area use, so verify the specific rating your application needs rather than assuming a standard motor can be adapted.
