Vibration Research VR4022 Permanent Magnet Shaker

The Vibration Research VR4022 Permanent Magnet Shaker is used for both modal and general-purpose testing. The compact size and light weight of the Vibration Research VR4022 make it a very portable package suitable for desktop applications. The VR4022 lightweight armature shaker runs higher test levels without forced air cooling. It’s perfectly suited for testing of small transducers as well as electrical and mechanical assemblies. High lateral and axial stiffness reduce problems caused by off-center loads. Unsupported horizontal operation is possible on many loads. The frequency limit of 7000Hz satisfies high frequency test requirements.
