Compumotor takes a system approach to solving your application and builds an integrated family of products to match your needs. Compumotor builds products in three categories: Motors, Drives and Controls. By taking a system approach Compumotor is able to design systems which work very well together and can offer cabling solutions to ease the installation process. In addition, by designing a family of products, you can be assured that there is the documentation you need to complete your installation correctly. Even though most of Compumotor OEMs and Users use the whole system, we also design our products using standard industry interfaces so that each component can be applied individually. Compumotor strives to offer the right combination of systems and components to provide solutions for every application need.

Compumotor's mission is to delight our customers with innovative and easy to use products and services for electronic motion control applications. Compumotor achieves this by:

• Continuous improvement of product quality
• Company wide commitment to customer service
• Individual growth and team involvement

While working in research and development at Hewlett Packard, Ross Welbourn invented a method to enhance the resolution of the standard hybrid step motor. The idea, not yet feasible for production, was rejected by HP management and the entrepreneurial engineer was allowed to take the idea and start his own company. He teamed up with Jack Blakemore in 1979 and the two men founded CompuMotion Corporation in Petaluma, California.

Shortly afterwards, the first microstepping systems began to ship and the CompuMotion name was changed to Compumotor Corporation. Quickly gaining experience and customer feedback, the M Drive was developed and solidified Compumotor's success as a start-up. During the M Drives 19 year life cycle, over 60,000 M Drives were manufactured and sold. In - 2001 Compumotor will release the 6th generation of microstepping drives, the all digital Gemini Family.

Since there was never a product with the resolution of a microstepper before (25,000 steps/rev) Compumotor was required to also develop a family of controls for the new motor drive technology. The new controllers were called indexers and were the first devices with a pulse train high enough to control the microstepper. After 5 generations of successful control products, Compumotor has the 6K family of controls for servo motor and step motor applications.

After rapid growth to $15M, Compumotor was acquired by the Parker Hannifin Corporation in 1986. Parker is a worldwide leader in hydraulic and pneumatic motion and anticipated the importance of electromechanical motion. Compumotor equipment has been used to automate Parker machinery for the production of valves and fittings for the instrumentation and hydraulics groups. Compumotor plays an important role in the Automation group which provides systems for Electromechanical and Pneumatic control.

Compumotor invested in the development of servo products, and in 1995 began to manufacture a line of brushless servo motors. Today Compumotor has a complete line of servo motor systems to compliment its step motor heritage.
