The Electromagnetic Damper - Towards a First Large-Scale Industrial Application

Studies concerning the magnetic bearing were begun at the Research and Development Department when the first industrial applications on large machines appeared. Our work concerned, in particular, the modelling of this device and the construction of models used in performing validation tests. Furthermore these studies involved the search for new applications. Thus a largesized electromagnetic damper was constructed and tested on a second test bench to demonstrate that this solution may be applied to a large 900 MWe turbo-generator in operation.
