500 lbf Electrodynamic Exciter

Versatile Vibration Testing

The Modal Shop’s Electrodynamic Shaker Model 2500E is a 500 lbf pk sine force shaker designed for general-purpose vibration testing of small components, as well as stress screening of electronic and mechanical sub-assemblies. It is designed to re-create field vibration in a controlled laboratory setting and can be used in a variety of R&D, reliability, and quality assurance applications within the automotive, aerospace & defense, and consumer electronics sectors.

Model 2500E offers a large 6 in (152 mm) diameter specimen mounting table, making it easy to adapt to almost any test requirement with a minimum of fixturing. The table provides multiple internally threaded attachment points, making the shaker assembly ideally suited for applications such as production screening, reliability acceptance testing, and product engineering evaluation. The composite materials used for the armature suspension and guidance system provide a high degree of lateral and rotational restraint while maintaining maximum compliance in the axis of motion to permit full 1.0 in (25 mm) peak to peak stroke. The shaker and trunnion base assembly allow a variety of operating positions ranging from a standard vertical orientation to a rotation of 90° to interface with horizontal tables.

Model 2500E has an inherently low stray magnetic field, which is minimized even further by the use of a built-in degauss coil. Safety features include over travel switch protection, air-cooling flow interlocks, and safe start in mute mode associated with the Model 2050E12‑7 Digital Power Amplifier. Optional accessories are available such as special vibration isolation mounts, metric inserts for specimen mounting, and a magnesium head expander.
