Why choose EA electromechanical systems over hydraulic machines
As the demand for more sustainable, efficient, and high-performance testing solutions grows, electromechanical systems are rapidly replacing traditional hydraulic machines. The EA Series by STEP Lab leads this evolution thanks to its cutting-edge control, high force capacity, and long-term reliability in a compact and clean package.
The limitations of hydraulic systems
Hydraulic testing machines have long been a standard in mechanical testing, but they come with significant limitations that no longer align with the priorities of modern labs and R&D environments:
- High maintenance: Regular servicing, oil changes, and component wear lead to increased downtime and costs.
- Energy inefficiency: Hydraulic pumps consume a constant amount of power (even when idle) driving up operational costs.
- Complex installation: Hydraulic systems require dedicated infrastructure, including cooling units and fluid management.
- Safety and environmental concerns: Leaks and high-pressure components can pose hazards, while hydraulic fluids require special disposal.
In applications where precision, uptime, and flexibility are critical, these systems can become more of a burden than a benefit.
Why EA electromechanical systems are the smarter choice
Designed with modern testing needs in mind, the EA Series from STEP Lab utilizes screw-driven actuators to deliver precise, clean, and efficient force. These systems are ideal for both static and dynamic applications and represent a long-term investment in productivity and reliability.
Key advantages of EA Series
Reduced operating costs
No fluids to replace, less frequent maintenance, and up to 70% lower energy consumption compared to hydraulic machines.
High dynamic performance
Test frequencies up to 30 Hz and force capacities from 2 to 200 kN, ideal for a wide range of mechanical tests.
Compact and clean design
EA machines occupy less space and integrate easily into any lab or production line. Moreover, they are without the mess of oil or external hydraulic units.
Maximum reliability
Electromechanical components are durable and stable over time, reducing the risk of unexpected failures.
Versatile testing capabilities
Perform tensile, compression, fatigue, cyclic, and custom testing with a single system.
Advanced control software
The integrated Test Center platform enables complete test customization, data acquisition, and real-time monitoring for any type of material or component.
