ELECTRODYNAMIC ACTUATORS WITH LINEAR MOTORS
STEP Lab is capitalizing on its specialization in the development of electrodynamic axes by producing a new series of machines for highly dynamic applications (e.g. car and motorbike shock absorbers). This new range of machines, all based on linear motors, is divided into two families: HUD and XUD. The former is also suitable for endurance tests due to its high continuous dynamic forces, the latter is dedicated to short-term tests with the achievement of higher accelerations.
These machines enjoy, in keeping with our tradition, the advantages inherent in electric machines.
