Abstract

Soft Magnetic Composites (SMC) allow the construction of electrical machines with three dimensional flux paths with maintainable effort, yielding high efficiency and outstanding power density. These are the typical requirements of automotive companies. The benefits of SMC-materials meet the demands of axial flux machines (AFM) very well, which offer a high power to weight ratio. This paper deals with the analysis and optimization of the AFM geometry. An analytical model defines the initial design parameters. Furthermore, the details of the magnetic circuit are optimized using 3D finite element (FE) simulations. Finally, the analytical model and the FE calculation are compared.
