LINEAR MOTOR-BASED SYSTEMS

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

UD

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

HUD

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

KUD

The KUD Series has been designed for long-term durability testing and high loads.

XUD

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