Design and Performance Analysis of a Transverse-Flux PMSG for Applications in Small Wind Turbines

Abstract

In this paper are presented the main steps for developing an analytical design methodology of Transverse Flux Permanent Magnet Synchronous Generators for its use in direct-drive small wind turbines. First, to attain this aim, it is proposed the full magnetic circuit representation of the TF-PMSG. Next, the nodal analysis technique is used to find an algebraic expression for solving the airgap flux. The proposed analytical methodology has been coded in Matlab for analyzing the performance of the TF-PMSG’s over a full range of operation speeds and load conditions. Finally, the performance analysis of the TF-PMSG has been exhaustively validated through 3D Finite Element Analysis (FEA).
