Motor Driven Actuator

The Performance Required for Endurance Tests

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

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.

Power Savings of Approximately 75%

Power Savings of Approximately 75 % —Power Savings and Eco-Friendly Operation—
Power Savings of Approximately 75 %

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.

Labor-Saving System Changes

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

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.

Basic System
Electric jack unit (Option: Bracket mount and frame)
+ Servo amplifier
+ 4830 controller (Option: Software)

High Reliability and Ease of Use. Supporting Multi ple and Synchronized Tests —Expanded Testing via a High Performance Controller—

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.
