This paper presents the design, construction, and experimental performance evaluation of an axial flux magnetically geared permanent magnet (MGPM) machine for wind power application. The optimum electromagnetic design for both magnetically coupled and decoupled configurations is described. Considering the complex structure of the axial flux MGPM machine, special attention is also paid to the mechanical design aspects. The optimized results show that a torque density in excess of 100 kNm/m(3) could be achieved for the active gear part. The inherent overload protection of the MGPM machine has also been demonstrated. Furthermore, the design-related aspects and issues are analyzed and discussed in detail in an attempt to outline problem areas in the design process. Relevant discussions are given and conclusions are drawn.
