Electrodynamic shaker TV 69440/AIT series

Induction ring shakers operate with an all-metal moving coil with a single winding, in which an alternating voltage is induced by surrounding static coils, thus setting the moving coil in motion. Cooling is provided by a combined water/air cooler. The external cooling unit also provides the lubricant for the hydrostatic bearings, which enable friction-free mounting of the vibration armature. Advantages of induction ring shakers: • No power connection to the vibration armature necessary -> Less failure susceptibility • High mechanical strength of the moving coil -> Greatly reduced maintenance requirements • High acceleration values • High resonance frequency of the vibrating armature
