Ultra-Low Weight & Compact Sized Atom Dual-Axis Servo Drive Module
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 dual-axis Atom incorporates field proven rugged controller and high efficiency wide-bandgap semiconductor-based power driver modules and offers multiple configurations. It is designed and manufactured in ESI Motion’s USA facility and complies with a wide range of military and industry standards. Options include a selection of input voltages, output current amplitudes, and feedback devices. It comes with an industry benchmark user interface allowing the most flexible and precise system integration and control. With 100A packed into a very small package, the Atom is a powerful solution for your application. If you need a 50A single-axis version, check out the Proton!
