Motion Control Systems, Inc. was founded in 1985 to Design and Manufacture High Performance Drive Systems for both industry and government applications.

M.C.S. is located in Southwest Virginia in a 26,000 square foot facility near the Virginia Tech campus.

The Design focus has been on the development of extremely efficient  and reliable brushless DC motors and controllers having low torque ripple and cogging characteristics with systems ranging from under 1 HP to over 200 HP. These developments were critical to the computer industry in the development and manufacture of high density magnetic and optical disk storage. The same technology and techniques are applicable in other areas requiring high efficiency and low structure borne noise such as precision optical machining and underwater drive systems.

Standard Products Include:

Controllers - 4 basic product lines. All amplifiers feature sinusoidal motor commutation from a variety of feedback devices. Additional power ratings available.

• LA Series linear amplifiers up to 700VA
• SA Series PWM amplifiers up to 100 KVA
• AX Series PWM analog servo drives up to 200KVA

Brushless Servo Motors

• 16 basic motor frame sizes from 1.25 inch OD to 39 inches OD (32 - 990mm OD)
• Torques from a few oz-ins to over 660,000 lb-in (74,570 Nm)
• Custom sizes and housings available.

Application Areas Include:

• Machine tool drive systems for grinding and milling systems which produce up to 70HP at 25,000 RPM and can go as high as 150HP or 50,000 RPM
• Development, manufacture, and test of high-density magnetic and optical storage devices. Precision spindles equipped and driven with MCS controllers provide an ultra-stable rotational reference with speed control accuracy approaching one part per billion
• Low speed, high torque actuators
• Automotive power steering assist actuators
• High reliability motor systems used for machining in harsh hazardous environments
• Single point diamond turning lathes for precision machining
• In the optical industry our drives power high-speed grinding spindles used to manufacture lenses and molds, with precision drives that perform within dimensional tolerances of 20 angstroms
• Critical positioning applications for the automotive, aeronautical and automation industry
• Airborne main antenna drive system for early warning radar (speed control to better than 100ppm relative to the earth's surface)
• Many manned and unmanned underwater vehicles are powered by MCS submersible motors and controls. Our designs combine high performance with an ability to withstand the rigors of a corrosive underwater environment
• Gyro stabilized platform drive system
• Aircraft flight simulators
• Other MCS products include helicopter mounted drive systems used to deploy and retrieve mine detection systems, high-speed knitting machines and high-frequency, high-power position systems used in wind tunnel testing of helicopter blades
