Abstract

In this paper, the design and analysis of an axial flux permanent magnet generator is presented. Different types of structures with 3, 5, and 9 phases and different pole numbers are evaluated to get optimum performance for automotive applications. The winding structure is of concentrated type to get a compact structure. The structure is of a special design that is suitable for flux weakening in variable speeds. Flux weakening is done by a mechanical actuator to change the position of windings relative to each other. To confirm the machine performance and the design, analytical and three-dimensional finite-element numerical methods are implemented.
