Abstract

This paper presents the potential application of soft magnetic composite (SMC) material in low speed, directly driven, axial-flux permanent magnet (PM) wind generators. Comparative design studies are conducted on PM wind generators of different configurations with both lamination cores and SMC core. Finite element analysis is used to enhance the design precision, from which analytical formulas are modified. Through careful design an axial-flux PM wind generator with slotted SMC core is built and tested, demonstrating the advantages of better performance, reduced size and weight, low part count and low cost.
