Design and build-up of a high performance six-phase machine for an automotive application

In this paper the design and build-up of a high performance PM-machine is presented. The machine comprises a special six-phase winding which exhibits a very low harmonic content. The winding properties are discussed in detail. The design process of the machine is shown. 3D-FEM is used to accurately compute eddy current effects in the permanent magnets. The building process is shown with respect to special challenges. Finally computed results are provided.
