Actuator
The electromagnetic actuator is coupled with low-friction bearings to achieve high waveform reproducibility.

Electric Crosshead Drive and Manual Clamp Levers
The crosshead can be raised or lowered using an electric switch. The crosshead can be immobilized easily
Load cell
using manual clamp levers. EHF Series Electric Hydraulic Dynamic and Fatigue Testing System
Emergency stop switch
Servo Controller 4830 and Control/Data Analysis Software
The controller allows high-performance and high-functionality dynamic and fatigue testing.

Power Amplifier Unit
Internal electronic power circuits are used to drive the electromagnetic actuator. The top surface can be used
as a table for the controller.

Dual-Stage Crosshead Drive Mechanism

Using two buttons to operate the crosshead and clamps helps prevent operating errors and accidents. Air-cooling unit (inside main unit)

The above characteristic curves indicate the relation between half-amplitude and cycle speed during sine wave motion.
The above characteristics do not include the frame, load cell, or sample characteristics. Compensate for the in uence of these factors
to determine actual amplitude characteristics.
