Passive electromagnetic damping device for motion control of building structures
… control of motion in building structures: an electromagnetic damper. The electromagnetic damper is a self-excited device that provides a reaction force to an applied motion. We chose a tubular permanent-magnet linear machine as this new structural damper, and we derive its mathematical model …

A study on energy harvesting through the use of electromagnetic dampers in motion control schemes
… concepts. This study investigates the use of the electromagnetic damper as an energy harvesting device in multiple damping schemes. It is shown that the use of the electromagnetic damper in a tuned mass damper scheme produces the most available energy to be harvested.

Investigation into low power active electromagnetic damping for automotive applications
… and passenger comfort. Hydraulic passive dampers are the most common system employed on vehicles, yet it is well known that passive suspension systems are less effective on lightweight vehicles. Modern damper technologies such as semi-active and active dampers, offer potential benefits …

Development of Novel Eddy Current Dampers for the Suppression of Structural Vibrations
… structure is to use magnetic damping. Magnetic dampers function through the eddy currents that are generated in a conductive material that experiences a time varying magnetic field. However, following the generation of these currents, the internal resistance of the conductor causes them to …
