Electromechanical Servo Testing Actuators

These versatile electromechanical servo testing actuators are suitable for tensile and compression applications and can be integrated into testing devices with various configurations. Areas of use range from materials and component testing to the testing of finished end products. They also enable testing in stages of production (for example, assembling/joining, force fitting, and assembly) and are suitable for long-stroke cyclic fatigue strength tests.

  • Accessory cards and interfaces are available for easy integration in production lines.

Advantages & features

Advantages and features

  • Flexible usage:
  • Variable mounting via front or rear flange or via trunion mount
  • measurement and control electronics testControl II in seperate casing and therewith optional positionable (Optional in IP54 casing)
  • Flexible programming of test sequences due to versatile interfaces
  • Ideally usage for clean room areas
  • Easy to install and maintain:
  • Installation possible without additional infrastructure (like e.g. hydraulic pumps or pneumatic connections)
  • Low maintenance costs and long lifetime
  • Large variety of standard modules:
  • Easy mounting of Zwick load cells and tooling
  • Operation via standard PC and testXpert ® II software
  • Proven digital drive technology controlled by Zwick standard electronics

Applications for Electromechanical Servo Testing Actuators

Portal Solutions with Electromechanical Servo Testing Actuators

Testing situations involving large components such as car seats, furniture, wall panels, and vehicle bodywork parts require large, flexible test devices. The portal design of the load frame provides convenient operation and a wide range of adjustment options. The portals have a modular construction allowing them to be configured easily for testing requirements. The T-slotted basic platform, portal, and electromechanical servo testing actuator are all available in various sizes and shapes.

Zwick electromechanical servo testing actuators are available in six versions: 1, 2, 5, 10, 20 and 30 kN and 5kN or 30kN portals are selected as appropriate. For the T-slotted base platform there are various standard sizes; special sizes are available on request. The position of the testing actuator in the X, Y, and Z axes can be adjusted manually or via an electric motor.

Various safety cabins are available in accordance with overall size. Stiff, robust construction enables high measurement accuracy levels without additional measuring transducers in most cases.
