OPEN ACCESS
An Axial Flux Permanent Magnet synchronous (AFPM) generator dedicated to small wind turbine is presented. Hence, the investigation of electromagnetic performance is done using quasi-3D analytical model based on multi-slice 2D analytical solution of Maxwell equations coupled sequentially to thermal model and mechanical model for rotor thickness study and vibration behaviour. The manufactured prototype has 10 kW rated power and operates at 375 rpm. This three-phase direct drive generator has double-stator-single-rotor configuration with 20 poles, 24 slots and modular windings. Experimental results such as Electromotive Forces (EMF) and inductances are agreed with those obtained from analytical simulation; both of them have been satisfying the desired technical specifications.
