Ultra-Low Weight & Compact Single-Axis Sized Servo Drive System

ESI Motion’s servo drive systems are designed for precision military, aviation, automotive, robotics, and specialized industrial applications where size and weight are critical. ESI Motion’s Single-Axis Proton leads the industry with its extremely small size and low weight. The Proton is a high-performance digital servo controller that can source 50 Amps with an 80 VDC bus to drive the most demanding applications. These tiny drives have a high-power density and proven field reliability.

If you need a dual axis drive which isn’t much larger, check out the (up to) 100A Atom!

Both drives are now available in EtherCAT!
