High accuracy test control is enabled by a special servo motor and stroke displacement measurement sensor. In addition, the system configuration is simpler in comparison to hydraulic actuators, so it is easy to maintain, and achieves power savings and space savings.
The same test force capacity is guaranteed in static tests and dynamic tests.
High speed tests at up to 72 cm/sec are supported.
The system achieves high peak reproducibility, and high accuracy measurement and control.
The electric motor driven actuator only uses the power output required for each test, so power consumption is substantially reduced in comparison to hydraulic actuators with similar specifications. If a 10 kN system is used, power consumption can be reduced approximately 75 %, and CO2 emissions can be reduced approximately 305 kg.
- When implementing 7 day testing with a displacement of ±40 mm and a test force of ±2.3 kN
- Power conversion factor: 0.378 kg-CO2/kWh
- During actual use, power consumption will differ depending on the installation conditions and the room temperature.
The electric motor driven actuator can be driven solely by a servo amplifier anda 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 simplifies 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.

Easier, More Convenient, and More Sophisticated
Thanks to highly responsive control and accurate waveform reproducibility, loads can be applied to products with high accuracy input waveforms.
Thanks to stable waveform input, the system is capable of endurance testing with high accuracy and high reproducibility, and the evaluation of slight differences in product performance.
