英文摘要：

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.
