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!

I/O Board for the Atom Servo Drive Modules
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 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.
The Atom I/O Boards are an optional circuit board that can be purchased along with the Atom Servo Modules.
The I/O Board provides the user with a platform that can be used for system development, prior to the design of a user-defined board that will mate with the Atom Servo Drive Module.
The I/O Board provides all the connections necessary for motor control. Signals are arranged by connector into three groups:
J3 Motor A Feedback, J4 System, and J6 Motor B Feedback. Voltages are: VBUS Input Power on J8, 28VDC IN on J4, and Motor A & B Power Outputs on J2 and J5, respectively.
Refer to Atom Datasheet for the electrical characteristics of signals and voltages.
A 5V regulator on the I/O Board is used to power both the Atom Servo Module controller (VLOGIC) and external motor feedback devices (up to 0.5A). The I/O Board is designed to work with Main Power (VDC_IN) from 10V to 90V.
