performance analysis of a novel threephase axial flux switching permanent magnet generator with overlapping concentrated winding

This paper proposes a novel axial flux switching permanent magnet generator for small wind turbine applications. surface mounted axial flux switching permanent magnet (smafspm) machine is a new type of these machines that is introduced in this paper. one of the most important challenges in optimal designing of this kind of machines, is ease of construction and maintenance. one of the main features of this machine is putting the magnets on the surface, which makes the construction of the machine easier. the overlapped threephase winding improves the quality of voltages and power of the machine.to reach the optimum dimensions of machine, centeral composite design (ccd) and response surface methodology (rsm) combined with 3d finite element methods have been used.
