Modeling and prototyping of axial flux permanent magnet machine for small wind turbine

The aim of this paper is to present the analysis and prototyping of an axial flux permanent magnet synchronous machine dedicated to a small wind turbine. The analysis of the generator was made with a quasi-3D analytical model based on a multi-slice 2D analytical solution of Maxwell equations coupled sequentially to a thermal model and a mechanical model. The designed generator is a 10 kW, 375 rpm, stator-rotor-stator structure with 20 poles, 24 slots, and modular windings. Results issued from measurements are satisfactory compared to those issued from analytical model.
