Abstract :
Roebel bars utilized in slots of synchronous machines consist of a large number of different anisotropic or isotropic materials combined in a complex production process. With the respect of industrial usage, the transmission of mechanical stress through the structure inside the slot is analyzed for three different kinds of material compositions.
