LINEAR MOTOR-BASED SYSTEMS

Our electrodynamic systems based on linear motors are the best solution for advanced dynamic and fatigue testing. We have divided our systems into the UD, HUD and XUD families, each designed with distinctive characteristics in terms of durability, dynamics and acceleration, making it suitable for performing a specific range of tests depending on the application.

UD

The UD Series is designed to perform continuous dynamic tests for millions of
cycles.

Technical Data
Sistemi di test dinamici e a fatica

HUD

The HUD Series has been designed for high dynamic and endurance tests due to the high continuous forces.

Technical Data

XUD

The XUD Series is designed for short duration tests with the achievement of high accelerations.
