Roadwind Series Drives

High Speed & High Current Servo Solution

High-speed servo applications often require a unique set of capabilities that are beyond what’s available in most of today’s drives. Fortunately, ESI’s Roadwind line of drives is designed for exactly this area, offering unmatched power density, speed ratings, and packaged in ESI Motion’s ruggedized casing.

An Integrated Drive System For Demanding Conditions


The Roadwind line is suitable for a wide variety of applications including ground defense, automotive, and specialized industrial projects. As with other ESI Motion drives, the Roadwind is a plug-and-play controller with a simple but powerful interface, and is built to survive extreme conditions. Unlike other drives, this power-dense controller functions at speeds of up to 300,000 RPM and currents of 300 Amps.

Ideal for both military and civilian use, the Roadwind line opens the door to large, high-velocity systems including hybrid and hybrid-electric vehicles, aeronautics, and industrial machinery and manufacturing. Prior to the Roadwind, the power and speed demands often drastically exceeded the abilities of today’s servo controllers.
