Damper testing machines
ECONOMICAL, PORTABLE, LINEAR MOTOR BASED SYSTEM FOR CARS, MOTORCYCLES AND TRUCKS
STEP Lab, responding to the request of cheaper, easy to use, high performance and green products, presents a new products line, for the characterization and high dynamic testing of shock absorbers. This new line is based on linear motors and its high performance Test Center software platform. The machines are suitable to test damper for cars, motorcycles and trucks. This new family of machines was born to overcome the limitations of hydraulic systems by effectively responding to the demand for high performance, ease of installation and low energy consumption. STEP Lab offers the widest range of electrodynamic systems on the market with peak dynamic loads up to 80 kN and continuous dynamic loads up to 40 kN. STEP Lab is also close to its customers giving the possibility of a wide customization both hardware and software.
Application areas
Exceptional dynamic performance and simple installation thanks to the request of only one electric socket and compressed air
Possibility to manage N machines in a synchronized way in order to realize multi-axis systems
Very low electrical consumption due to the high efficiency of the electric motor and absence of mechanical transmission
Zero maintenance due to the absence of a mechanical transmission
Flexible geometric configuration: machine can be purchased as linear actuator without structure
STEP Lab is proud to offer the widest range of linear motor based test systems. Our electrodynamic systems are divided into two families: one suitable for flexible use and one dedicated to the field where exceptional dynamics (up to 100G) are required. Both product families are managed by the same controller, scalable to the required performance and have the same software packages available. The HUD / XUD systems, developed for flexible use, have an exceptional price/performance ratio.
