The Modal Shop 2075E electrodynamic exciter is a small and lightweight, yet powerful permanent magnet shaker, providing up to 75 pounds (334N) pk sine force. A large armature (3.25 inch [8.3 cm] diameter platform table supporting payloads up to 7 lbs [3.2 kg]) makes the shaker ideal for traditional vibration control testing of components and subassemblies. The unit is also designed with a through-hole armature and includes a chuck and collet attachment, providing simple set-up with stingers for experimental modal analysis applications. When used in this configuration, these stingers greatly simplify test setup with an easy connection to the force sensor and test structure, and help decouple crossaxis force inputs, minimizing force measurement errors.
The shaker is supplied in a standard trunnion mounting base with EasyTurn™ handles, allowing operation through a large rotation for easy setup. Its armature suspension design provides excellent axial compliance with high lateral stiffness. There are no rolling or sliding components to wear out or produce unwanted noise and distortion. Its 1 inch (25.4 mm) stroke, wide frequency range (useable to 6500 Hz), and innovative dual-purpose platform table design support a very broad range of applications.
