Electric servo-actuator NJ-SERVO

linearwith servo-motorservo-motor

Overview
The NJ-SERVO electric motor driven actuator uses an electric motor drive system with a dedicated servo motor and a stroke displacement measurement sensor to enable high-accuracy test control. Compared with hydraulic actuators, the system configuration is simpler, easing maintenance while reducing power consumption and footprint. The system supports a wide range of test types and offers high expandability, from endurance evaluations of vehicle and aircraft bodies and assemblies to endurance tests of standalone parts; from multi-axis configurations combining multiple actuators to uniaxial tests; and from sine wave excitation to working-waveform simulation tests.

Features

• Same test force capacity assured for static and dynamic tests
• Supports high-speed testing up to 72 cm/sec
• High peak reproducibility with high-accuracy measurement and control
• Approx. 75% power savings compared with hydraulic actuators of similar specifications; motor-driven operation supplies only the power required per test
• Simpler system configuration than hydraulic systems — easier maintenance and space savings
• High expandability for various test types (endurance of assemblies, parts testing, multi-axis and uniaxial tests)
• Supports waveform types from sine waves to working-waveform simulation
• Can be driven solely by a servo amplifier and a controller for simplified system integration
