eMpulse Test Systems

Servoelectric Load Frames

At eMpulse Test Systems, our servoelectric load frames provide precise force and displacement control for single-axis durability, fatigue, and structural testing. Engineered for high dynamic performance and superior reliability, these systems support a range of testing applications, including damper characterization, elastomer testing, and structural component evaluation. Unlike traditional hydraulic load frames, eMpulse systems utilize servoelectric actuators (SEA), delivering higher accuracy, reduced maintenance, and up to 80% energy savings.

With full digital control, integrated diagnostics, and high-bandwidth operation, our load frames enable real-time force, velocity, and displacement feedback, ensuring repeatable and precise test execution. Available in various force capacities, they are adaptable to automotive, aerospace, and industrial applications, meeting SAE, ISO, and industry standards for rigorous material and component testing.

Advantages of Servoelectric Load Frames

Pedestal Style

Pedestal style servo electric linear motors form the base of the standard two column load frames.

Thermal Management for Extended Testing

Increased efficiency in converting electrical to mechanical energy, results in significantly lower heat generation. This improved efficiency reduces the size of the active cooling infrastructure, minimizes thermal loading on components, and contributes to lower overall operational costs.

High-Frequency Capability

Motor coherence up to 400 Hz enables test profiles that demand high dynamic response, exceeding the capabilities of servo-hydraulic actuators.

Solid Welded Construction

Precision CNC machined and ground surfaces to 0.0001” tolerances to ensure perfect alignment for system longevity. Nickel plating surfaces resist long-term corrosion better than zinc, powder-coating or paint.

Force Range and Modular Design

Modular motor configurations deliver peak dynamic forces from 1 kN to 108 kN, independent of static load.

Nanometer-Level Accuracy

Integrated displacement feedback systems offer <10 nm resolution, supporting high-precision test requirements.

Sideload Capacity

Outboard bearings significantly improve sideload tolerance, outperforming comparable servohydraulic systems in lateral stability and reliability.

Pneumatic Support

Patented Integrated high volume Air-bag pneumatic support system for no maintenance and long-term durability.

Internal Motor Cooling

Internal motor cooling allows higher continuous force capacity to run extended or durability test profiles.

High Fidelity

High fidelity 32-bit closed-loop control ensures smooth, accurate motion across all test speeds, without switching valve types or control strategies.

Application-Specific Software

Integrated with eMpulse controls that feature application-specific software, seaPLUS Load Frames are ideal for field data reproduction, sine sweep, or Power Spectral Density (PSD) profile replication.

Efficient, Clean Operation

Direct-drive electric motion is up to 80% more efficient than hydraulics, with no fluid handling, reduced maintenance, and a cleaner test environment.

Integrated Safety Features

These features are built into the control architecture to ensure operator safety and specimen integrity during every test cycle. Every system includes comprehensive safety monitoring:

  • Safe Limited Speed (SLS)
  • Safe Limited Acceleration (SLA)
  • Absolute encoder fault detection
  • Safe Torque Off (STO)
  • Internal motor/drive temperature monitoring
  • Customizable specimen-specific protection limits
