Servo Drives

Find The Perfect Servo Drive For Every Application

ESI Motion’s rugged servo drives lines are designed to improve delivery time and reduce costs without sacrificing quality. Ideal for ground defense, aerospace, naval and specialized industrial applications, each line can be further customized based on your specific needs, or used as a turnkey solution. Our integrated modular systems combine all critical functions into a single unit that is lightweight and rugged. We offer multiple configurations for each line that can be suited to various environmental conditions including high temperature, high voltage and high-speed applications.

Fully Integrated Ruggedized Servo Drives

Designed for defense and specialized industrial applications, our fully integrated servo drive lines offer the most robust configurations. Available with military grade connectors and submersible cases, the Dragon, Vulcan and Roadwind lines offer lightweight, versatile plug and play capabilities for rapid deployment and integration. For systems that demand adaptable, lower-cost drives that can still function in high speed and high temperature environments, our Wolverine Line drives achieve the perfect balance of efficiency and reliability. These plug-and-play servo drives offer a wide range of configurations, shock and vibration resistance, and incredible speed and temperature tolerance. When projects have specific needs in terms of high speed and high power, our Hyperion Line really excels above the rest! Used on Formula One and other high power applications, these drives are a true achievement in engineering and provide incredible power and compact size and weight. It is the only ruggedized high power drive you can lift with one hand available on the market today.

Compact Servo Drive Modules

The Mite family of servo drive modules really shine! Our famous Dual Axis Mite servo drive matches the abilities of larger, more expensive servos in a package no bigger than your wallet. These drives are generally for high performing companies looking to package their own electronics or develop their own control systems. Available in single and dual axis, they are smaller, more lightweight and higher power density than any drives on the market.
