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!

I/O Board for the Proton 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 Proton 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 Proton I/O Boards are an optional circuit board that can be purchased along with the Proton or 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.
Key Features
| Facilitates fast initial integration and lab test | |
|---|---|
| Dual-axis (Motor A & Motor B) | |
| Standard connectors for: | VDC_IN |
| Motor A & B Power Outputs | |
| Motor A & B Feedback | |
| System (incl. Communications and 28VDC In) | |
| Brakes | |
| 5V and 3.3V Power LED Indicators | |
| Size: 2.2” L x 2.3” W x 0.5” D | |
| Brake drivers (it accepts TTL brake commands from the Atom and provides outputs to drive brakes) | |
