Abstract
A three-dimensional finite-element analysis is employed to investigate the losses of hydrogenerator stator end regions by using surface-impe dance boundary conditions. The three-dimensional complexity of the end -winding geometry is fully taken into account by the model. The purpos e of this work is also to evaluate the eddy-current paths allowing for slits in the stator teeth and their effectiveness in reducing stator core-end losses.
