ELECTRODYNAMIC ACTUATORS WITH LINEAR MOTORS

STEP Lab takes advantage of its specialization in the development of electrodynamic axes by realizing a new series of machines for very high dynamic applications (e.g. shock absorbers for cars and motorcycles). This new range of machines, all based on linear motors, is divided into two families: HUD and XUD. The first one is also suitable for endurance tests thanks to the high continuous dynamic forces, the second one dedicated to short duration tests with the achievement of higher accelerations.
These machines enjoy, as per our tradition, the advantages inherent in electric machines.

No maintenance
