Flux Switching Permanent Magnet machines have attracted considerable attention due to their simple and robust structure, easy heat dissipation, high torque densities and suitability for high-speed operations. To enhance these proprieties, we present in this paper an analytical model for prediction of the magnetic field for a 3 phase, 12 stator slots and 10 rotor tooth (12/10) flux switching permanent...
This paper presents a detailed study of the impact of the airgap magnetic field harmonics on some performances of a disc-type switching flux permanent magnet generator. More precisely, the presented study concerns the cogging torque, the total torque as well as the torque ripple, the eddy currents in the permanent magnets and finally the vibro-acoustic emissions due to electromagnetic origins. First,...
This paper focuses on some aspects of the mechanical behaviour of a discoidal switching flux permanent magnet generator in three sections. The first one deals with torque ripple reduction by the identification of the optimal rotor tooth size. The second one focus on the common problem of the rotor's mechanical strength in axial flux machines studying their deflection and optimal design for mass reduction...
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,...
