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
