ESI Motion's New Proton 4kW Servo Drive Module

POSTED 09/09/2021

New Proton Single-Axis Servo Drive Module with CAN, CANOpen, EtherCAT, and RS422

At ESI Motion, we understand the importance of precision. Whether using a servo drive for military, robotics, automotive, aviation, or other specialized applications, our servo drives are made and designed to perform! 

As a world leader in small efficient servo drives, ESI Motion’s Proton is our newest, single-axis module, designed to operate in small applications without sacrificing any power.

Features include: 8V- 80V Bus DC Voltage, Continuous Output Current of 50A, 50A Peak Motor Current and a Output Power of 4kW. 

The single-axis Proton is ultra-lightweight and compact (not much bigger than a quarter) and weighing it at just 0.59 oz (16.72 g) allowing it to be configured for a variety of applications where size and weight is critical.

With options to include input voltages, output current amplitudes, as well as feedback devices, a wide temperature range, among many more, the applications that this  servo drive can be used in is seemingly endless.

Our servo drive modules are designed and manufactured in our industry-leading facility in California, USA and are in compliance with a wide range of military as well as industry standards. With its rugged, field tested controller and it’s high-efficiency wide-bandgap semiconductor-based power driver, the Proton can be incorporated into just about any project – from an AGV, Medical Application, Robotic Suit, EV, Mobile Devices, or robotic arm positioner to radar systems and airborne antenna stabilizers.

Communications interface include:  RS422, CAN, CANOpen, EtherCAT
