Study of stator core-end packets under the action of two incident fluxes — Real scale model

This paper describes an experimental procedure for characterization of electromagnetic phenomena that occur in the end regions of large turbo-generators. The test bench contains a stack of steel laminations from a 900MW turbo-generator stator and two exciting circuits in order to combine a transverse magnetic flux with the in-plane flux. The theoretical and experimental results will be analyzed with a view to examine the influence of transverse flux on losses.
