Abstract: This paper presents the integrated design, analysis and performance test of a 1.4 kW, radial-flux, permanent-magnet generator applied to small wind energy conversion system (WECS). In a small WECS, the three major components, i.e., turbine, generator and converter, need to be considered all together to gain a maximum overall efficiency, instead of only chasing high performance of individual components. Therefore, the integrated design approach developed for generators in this paper simultaneously considers the characteristics of turbine blades and power electronics for maximum electrical power generation. Finite element analysis (FEA) is employed to verify the design. The performance test shows that the generator prototype has an efficiency of 91% at the design operating condition and the output satisfies the requirement.
