OMS Motion Inc. Product
Member Since 2008
OMS Motion, located in Beaverton, Oregon, has been successfully producing motion controllers for more than 35 years. OMS Motion was founded as Oregon Micro Systems (OMS) and evolved from patented motion control technology that provide superior advantages in the industry. OMS built a strong reputation in the market for reliable and quality motion control products backed by superior customer service and technical support. These motion controllers can control 10 axes of motion on a single controller for servo and/or stepper motor control. OMS also produces integrated controller & drive in small compact sizes for deployment near or on the motor. Applications of OMS products include semiconductor and medical equipment, life sciences and factory automation markets, as well as research facilities around the world. In addition to creating multi-axis motion controllers, OMS offers motors, drives and accessories that are often tailor-made to support specific applications.

OMA-21 is a small formfactor servo amplifier and controller capable of Sensorless, Hall sensors, Incremental or Absolute Encoders (SSI or BiSS).
The OMA-21 is a small formfactor servo amplifier and controller capable of Sensorless, Hall sensors, Incremental or
Absolute Encoders (SSI or BiSS). Ideal for managing motors of 140W or less in a tightly controlled feedback loop for
superior performance. The OMA-21 communication is through USB 2.0 and offers more than 170 motion commands for
a variety of application requirements. The OMA operates from a single power supply of 15 to 50 VDC and is internally
monitored for overcurrent and overvoltage. Overtravel limit and home inputs are included as well as up to 8 general
purpose I/O. The small size outline matches the NEMA23 frame motor dimensions for flexible mounting options.
