The Performance Required for Endurance Tests
                      —High Accuracy, High Speed, and Stable Control—



               The same test force capacity is guaranteed in static tests and dynamic tests.                        EHF Series  Electric Hydraulic Dynamic and Fatigue Testing System
               The system accommodates everything from static to dynamic tests across the full actuator capacity range.
               The test conditions can be set as you wish.

               High speed tests at up to 72 cm/sec are supported.
               High speed control is achieved at 72 cm/sec in single wave tests and 50
               m/sec in continuous endurance tests.
               It can be applied to a variety of tests at low to high speeds.

               The system achieves high peak reproducibility,
               and high accuracy measurement and control.
               High accuracy measurements are achieved thanks to the built in stroke
               sensor and a special load cell for dynamic testing.
               High stability test peaks are achieved thanks to the high response control of
               the 4830 controller.                                                                                 EMT/NJ-SERVO/MMT Series  Electric Fatigue and Endurance Test System

                               Labor-Saving System Changes
                               —Space Savings and Minimum Maintenance Required—


            The electric motor driven actuator can be driven solely by a servo ampli er and a controller.
            In contrast to a hydraulic type testing system, thick hydraulic hoses and a hydraulic power
            supply are not necessary. This saves on space, makes the system easy to move, and simpli es
            testing system changes.
            Naturally, it is motor driven, so there is no need for periodic replacement of hydraulic oil, and
            hydraulic servo valve overhauls are not required.                                                        Various Dynamic Testing Systems
