When a reduction of vibration amplitude usually designers resort to dampers based either on dry friction, internal material damping or fluid viscosity, each one of these mechanisms having its peculiar field of application. To improve performance while at the same time reducing costs and environmental load, electromagnetic damping devices are finding new applications, beyond the fields where they have a long history. Moreover, electromagnetic dampers can be easily controlled, obtain active or even ‘intelligent’ vibration control. Three examples from the internal combustion engines, automotive and gas turbine fields are discussed in some detail to show the potential advantages of this technology.
