Abstract: A general classification of Axial Flux Permanent Magnet (AFPM) synchronous machine topologies was described. The bad flux-weakening capability is a common shortage of different topologies. The flux-weakening methods for AFPM synchronous machine were summarized. The principles and effects of different methods were described. The reference for flux-weakening method choosing and new researching was provided.

Key words: axial flux; AFPM; permanent magnet synchronous machine; flux-weakening
