Testing lab and innovation: the future is electric
STEP Lab

Back in 1955, mechanical testing labs saw the first testing revolution: hydraulic technology was applied for the first time on a testing machine. After six decades, we’re beginning the second testing revolution: electrical technology is ready to disrupt hydraulic in labs.

STEP Lab was born in 2009, and from the first day it began studying and developing dynamic and high-load testing systems based on electrical motions. STEP Lab is focused on technologies that could replace older oil-based ones. The product range is currently divided into two main groups. First, electrodynamic actuators, based on high dynamic linear motors. This technology is the best on the market for dynamic tests on position and force control loops, with test frequency greater than 200Hz and acceleration above 910m/s2 (93g); high strain rate tests; and in-lab reproduction of the acquisition of time history with high dynamics, for example the loads applied on a downhill’s fork or on a motorbike’s suspension. The maximum dynamic load reached by STEP Lab electrodynamic actuators is 40kN.

The second technology is electromechanical actuators, based on a special ball screw, specifically developed for testing applications. This technology is the best solution for dynamic tests on position and force control loops up to 35Hz, with acceleration up to 20m/s2; static tests on position control loops; and static tests on force control loops (creep tests). Currently, the electromechanical actuator’s product range covers a wide force range, from 1.5kN to 225kN of dynamic force and from 5kN to 195kN of static force.

Last but not least, STEP Lab is an important producer of drop weight towers for impact tests.
